These genes are 30 units apart on chromosome III. In this problem, you will calculate what crossing over in the female contributes to the phenotypic results. Part A Which combination(s) of alleles does the male parent contribute to the offspring?

This exercise is incomplete. The response options are as follows:

a) e+ ca+

b) e ca

c) e ca+

d) e+ ca

The answer is c) e ca+ and d) e+ ca

Explanation:

The Punnett square is a diagram used by biologists to calculate the probability that an individual has a particular genotype. In the Punnett square, each of the possible combinations for the expression of the dominant and recessive alleles can be observed. In the case of exercise, since a crossing is not possible in men, these will only help later during the combination of the alleles.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
