Write your answer as a fraction or a decimal, rounded to four decimal places. Gene Dominant Recessive Gene Dominant Recessive (a) What is the probability that in a randomly sampled individual, gene is recessive

Answers

Complete question:

A geneticist is studying two genes. each gene can be either dominant or recessive. a sample of 100 individuals is categorized as follows.

                                         gene 2

                            dominant     recessive

gene 1

dominant                    56                24

recessive                   14                  6

(a) what is the probability that a random sampled individual, gene 1 is dominant

(b) what is the probability that a random sampled individual, gene 2 is dominant

(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant

Answer:

(a) what is the probability that a randomly sampled individual, gene 1 is dominant ---> 80%

(b) what is the probability that a randomly sampled individual, gene 2 is dominant ----> 70%

(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant ----> 70%

Due to technical problems, you will find the complete question, the answer, and the explanation in the attached files.

In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve. Determine the F1 results of a cross between true-breeding red and true-breeding mauve flowered plants.

Answers

Answer:

F1) 100% bbRr, red flowered plants.

Explanation:

Available data:

flowers may be yellow, blue, red, or mauvecolors may be true-breedingthe cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowersF2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.

Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).

According to the first cross, we might establish the following genotypes:

1st Cross: blue-flowered plant     x     red-flowered plant

Parentals)         BBrr                     x                bbRR

Gametes)     Br, Br, Br, Br                         bR, bR, bR, bR

F1) 100% BbRr, yellow plants

Parentals)   BbRr     x     BbRr

Gametes) BR, Br, bR, br

                BR, Br, bR, br

Punnett square)     BR       Br        bR          br

                  BR     BBRR    BBRr   BbRR     BbRr

                  Br      BBRr     BBrr     BbRr      Bbrr

                  bR     BbRR    BbRr    bbRR      bbRr                    

                  br      BbRr     Bbrr      bbRr      bbrr

F2)  9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR  

       3/16 blue ------> 1/16 BBrr + 2/16 Bbrr

       3/16 red---------> 1/16 bbRR + 2/16 bbRr

       1/16 mauve ----> 1/16 bbrr    

So,

Yellow-flowered plants: BBRR, BBRr, BbRR, BbRrRed-flowered plants: bbRR, bbRrBlue-flowered plants: BBrr, BbrrMauve-flowered plants: bbrr

According to these genotypes, the second cross would be like following,

2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.                

Parentals)          bbRR       x        bbrr

Phenotype)       Red                   Mauve

Gametes)   bR, bR, bR, bR      br, br, br, br

Punnett square)    bR       bR        bR        bR                    

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

F1) 100% bbRr, red flowered plants.

In addition to lipids, membranes are loaded with proteins. In fact, proteins account for roughly half the mass of most cellular membranes. Many of these proteins are embedded into the membrane and stick out on both sides; these are called transmembrane proteins.The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable.In addition to the phospholipids, the plasma membranes of animal cells contain glycolipids and cholesterol. ... Because the interior of the phospholipid bilayer is occupied by

Which scientific area has the most influence in shaping modern classification methods?

Answers

Answer: The answer is " evolution". Evolution is a major force in shaping modern classification methods. Evolution is the adjustment in the qualities of an animal categories more than a few ages and depends on the procedure of common determination.

The scientific field which has had the greatest influence on shaping modern classification methods is Evolution.

What is Evolution?

Evolution is concerned with the sequence of changes which occur in organisms as they transform from their ancient forms to their modern forms.

It is the change in the genetic characteristics of a biological population over successive generations. These characteristics are manifestations of genes passed from parents to offspring during reproduction.

The three main types of Evolution are:

1. Divergent Evolution

2. Convergent Evolution

3. Parallel Evolution

Thus, the scientific field which has had the greatest influence on shaping modern classification methods is Evolution.
