The correct answer is 4.
Here’s a step-by-step explanation:
1. The genotype RRYy consists of two alleles for the R locus (RR) and two alleles for the Y locus (Yy).
2. The R locus can only produce one type of gamete (R) since both alleles are identical (RR).
3. The Y locus can produce two types of gametes (Y and y) because it has one dominant allele (Y) and one recessive allele (y).
4. When we combine these, the total number of different gametes can be calculated as follows:
– From RR, we can get 1 type (R).
– From Yy, we can get 2 types (Y and y).
5. Therefore, the total number of different gametes is: 1 (from R) × 2 (from Yy) = 2.
However, I made a mistake in the initial calculation. The possible combinations of gametes are:
– RY
– Ry
This means that the total distinct combinations equals 2.
So the correct answer is actually 2.
