Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d). A pigment-eyed, dimple-chinned man marries a blue-eyed woman without a dimpled chin. Their firstborn child is blue-eyed and has a dimpled chin. What are the possible genotypes of the father
Answers
Answer:
PpDD and PpDd
Explanation:
Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).
The possible genotypes of a pigment-eyed, dimple-chinned person would be PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.
The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.
In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).
Hence, the genotype of the father is now limited to PpDD and PpDd.

B.CFCs
C. oil spill
D.runoff
Quick this is a timed exam
Answers
Answer:
B) CFCs
Explanation:
chlorine in the CFC is very harmful to the ozone layer
Air pollution is the contamination of the air and its surroundings due to air pollutants. Chlorofluorocarbons (CFCs) are most likely a source of air pollution. Thus, option B is correct.
What are Chlorofluorocarbons?Chlorofluorocarbons (CFCs) are nontoxic chemicals that contain chlorine, fluorine, and carbon. They are largely used in the manufacturing of refrigerants, foams, sprays, etc.
Chlorofluorocarbons destroy the protective ozone layer of the earth and affect its ability to shield the harmful UV rays from the sun. Due to their dangerous effect on the ozone, they are banned.
They are emitted and get deposited in the earth's atmosphere causing the greenhouse effect that causes the melting of the ice and increases in the sea level to rise in temperature.
Therefore, chlorofluorocarbons are the source of air pollution.

Road construction has isolated a small population of a beetle population from the main population. This newly isolated population has very different allele frequencies than the main population, most probably because
Answers
Answer:
genetic drift
Explanation:
The newly isolated population of beetle would have very different allele frequencies than the main population because of genetic drift.
Genetic drift refers to a change in the frequencies of alleles in a population over generations brought about by pure chance. Genetic drift can cause a bottleneck or founder effect. A bottleneck effect is a temporary decrease in the genetic diversity of a population while the founder effect refers to a decrease in the genetic variability of a new population formed from a small number of individuals that get separated from a larger population.
Hence, the newly formed population of beetles would have lower allele frequencies than the main population due to the founder effect brought about by genetic drift.

What change is most likely
responsible for the trout decline? *
Answers
Answer:
Rise in temperature.
Explanation:
Increase in temperature is responsible for the decline in the population of trout because trout needs low temperature for better growth and survival. Due to more consumption of fossil fuels in vehicles and industries, more carbondioxide gas is released which causes air pollution. This air pollution increases the temperature of the earth surface known as global warming due to which the cold areas become warm and as a result the trout population decreases.
Sierra is asked to demonstrate how carbon travels from the atmosphere to living organisms, then back to the atmosphere.

Answer: An animal then consumes the carbon dioxide in the plant, uses it as a source of energy, then exhales, returning the carbon dioxide to the atmosphere.
Explanation: This is incorrect, because animals consume oxygen released by plants, then exhale the carbon dioxide into the atmosphere.
Answer:
B
Explanation:
Animals do not use carbon dioxide as an energy source; they use sugars or starches.

In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is:
X----------------Y-------------------------Z
20 m.u. 30 m.u.
You cross an individual with genotype XXYYZZ to an individual with genotype xxyyzz, and F1 progeny are collected. Assume interference between regions (X-Y and Y-Z) is 100%. When an F1 individual produces gametes, what proportion of its gametes would have xyz genotype?
a. 10%
b. 20%
c. 25%
d. 30%
e. 40%
f. 50%
g. 0%
h. None of these above
Answers
In F1 we will get 100% XxYyZz
each of these organism has two chromosomes that look like this
X..........20..........Y...............30...............Z
x..........20..........y...............30...............z
Those two chromosomes are homologous
we want a gamete that contains the second chromosome where crossing-over didn't occur. The distance between the genes of the chromosomes in map units is equal to the frequency of recombination in percentage. Therefore there is a 20% that x and y will recombine and a 30% chance that y and z will recombine. We want a chromosome that is not recombined.
The possible gametes are
XYZ XYz XyZ Xyz xYZ xYz xyZ xyz if the genes were on different chromosomes xyz would be 1/8 or 12,5%
Since there is a 20% that the genes x and y will recombine that means there is a 80% chance that they won't and since there is a 30% chance that the genes y and z will recombine that means there is a 70% chance that they won't.
80%*70%=56% chances that the genes won't recombine. But, there are two non-recombinant gametes:XYZ and xyz therefore the chances for xyz is 56/2=28%
In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is: X----------------Y-------------------------Z, When an F1 individual produces gametes, we will get 100% gametes would have xyz genotype that is XxYyZz, it can be represented as
X..........20..........Y...............30...............Z
x..........20..........y...............30...............z
What is chromosome ?A chromosome can be observed as a thread-like structure present in the nucleus of cells such as plant, animal and human cells, composed of DNA (Deoxyribonucleic acid) molecule and histone proteins.
The three major components, DNA, proteins and RNA, the content of the DNA ranges from 30 to 40 % whereas proteins from 50 to 65%, and small amount of RNA ranges from 1 to 10%.
Two types of protein present such as histone and non-histones proteins, histone content is more (90% of total protein), whereas non-histone is content is less (around 10% of total protein).
The histone protein is basic, the DNA is acidic which can be neutralized; DNA is present in two forms such as Euchromatin and Heterochromatin.
20% that x and y will recombine and a 30% chance that y and z will recombine. We want a chromosome that is not recombined.
The possible gametes are XYZ XYz XyZ Xyz xYZ xYz xyZ xyz if the genes were on different chromosomes xyz would be 1/8 or 12,5%

Directions: Select the correct term or terms from the table. Different organisms have different traits, or characteristics. Some of an organism's traits are inherited from the organism's parents, while other traits are more strongly influenced by the organism's environment. Among most animals, which of the following traits are usually directly determined by genes inherited from the organism's parents? sex body weight knowledge blood type
Answers
Answer:
The correct answer is - sex and blood type.
Explanation:
Different organisms have different traits some are passed from the parents and other traits are developed by environmental influences. The traits that are passed from parents to the offspring are determined by the genes they inherited from the parents. In humans, sex is determined by the genes that present on the chromosomes and make the chromosome X chromosome or Y chromosome. The presence of the Y chromosome determines maleness.
Similarly, the blood group is determined by the genes, there are three alleles of the ABO gene present on chromosome 9; A. B. and O each allele code for a different antigen which helps them categorizing in blood groups.
