Question

Which of the following genotype pair given below
do not show same expression w.r.t. seed shape
and seed colour?

(2) RRYY ; RrYY ✔✔✔✔

Answer 2

The correct answer is (4)  rrYy : Rryy.

Explanation:

• This is because :

1. rr is homozygous recessive genotype and so it will show the recessive phenotype.
2. Rr is heterozygous dominant genotype and so it will show the dominant phenotype.
3. Yy is heterozygous dominant genotype and so it will show the dominant phenotype.
4. yy is homozygous recessive genotype and so it will show the recessive phenotype.
5. rrYy will show recessive phenotype for 'R' trait and dominant phenotype for 'Y' trait.
6. Rryy will show dominant phenotype for 'R' trait and recessive phenotype for 'Y' trait.
