Question

2. Now imagine a woman who is genotype Ee for ear wax and TT for tongue rolling mates a man whose is ee for earwax and Tt for tongue rolling (2 points) a. What possible gametes can the woman produce? b. What possible gametes can the man produce? REMEMBER: you are working with TWO traits now, and each gamete must contain one allele for both traits. OVER →

Answer 1

2.

Genotype of the woman is TTEe

Genotype of the Man is Ttee

a.

The woman can produce two types of gametes i. e. TE , Te

b. The man can produce two types of gametes I.e. Te , te

c.

d.

"T" is the dominant allele for tongue rolling. "t" is recessive allele. So if one copy of the "T" allele present then the offspring will be able to role their tongue.

"E" is the allele for sticky earwax. This is a dominant allele. "e" is the recessive allele for this trait.

So,

The Probability that they will have a child that can roll their tongue and has sticky earwax is 8/16 = 1/2 = 0.5

So the Probability is 50%.

e.

All offsprings possess at least 1 "T" allele. So the Probability of a child that can't roll their tongue is 0 .
