Your research work reveals that the genes for skin color and teeth shape in grindylows are both located in chromosome 12A. A bright green skin, sharp teeth grindylow (BBHH) was mated with a pale skin, round teeth(bbhh) grindylow.. An individual of the F1 is mated with a pale skin, round teeth individual and you observe that the frequency of grindylows with bright skin and rounded teeth is 20%. If two heterozygous grindilows are crossed together, what is the frequency in which bright green skin and rounded teeth grindilows vould be observed? Select one: a. 10% b.4% c. 16% d. 12% e. 6%

Respuesta :

Answer:

g

Explanation:

The frequency in which bright green skin and rounded teeth grindilows would be observed is 4%.

Probability of obtaining bright green skin and rounded teeth

The frequency in which bright green skin and rounded teeth grindilows would be observed will be determined from the probability of the individual grindilows.

P(1 bright green skin and rounded teeth grindilows)  = 20 % = 0.2

When 2 heterozygous grindilows are crossed, the probability is calculated as

P = P(1) and P(2)

P = 0.2 x 0.2 = 0.04 = 0.04(100%) = 4%

Thus, the frequency in which bright green skin and rounded teeth grindilows would be observed is 4%.
