In humans, dimples (D) are dominant over no dimples (d). Curly hair (A) is dominant over

straight hair (a). Paul, who is heterozygous for dimples and curly hair, marries Jane, who

has curly hair but does not have dimples. Jane's mother had straight hair, but her father had

curly hair. Paul and Jane had a child named Peter, who had curly hair but did not have

dimples.

Sagot :

Answer:

1. ddaa

2. DdAa

3. One from each parent

4. False

5. 0.25

6. 0.25

7. 0.25

8. 0.5

Explanation:

The remaining part of the question is  

1. What is Jane's genotype?  

2. What is Paul’s genotype?  

3. Where did Jane get her gene for curly hair? From her mother or father?  

4. True or False: Jane's mother was heterozygous for curly hair?

5. What fraction of Paul and Jane's children should have curly hair and dimples?  

6. What fraction of their children would have straight hair and no dimples?  

7. What fraction should have dimples but not curly hair?  

8. What is the probability of getting any offspring with dimples

Solution

1. Genotype of Jane's mother -ddaa

2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa

3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was  Aa)

4. False.  She was having straight hair

5. Offspring of  Paul and Jane  

DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)

4 out of 16 offspring will have curly hair and dimples = 0.25

6. ddaa, 4/16 = 0.25

7. Ddaa , 4/16 = 0.25

8. Ddaa, DdAa, 8/16 = 0.5
