To complete a Punnett square for the given genotypes, we need to identify which combinations of alleles can be produced from the parent genotypes.
Let’s break down the combinations:
1. For RrYy x RRyy:
– Possible gametes from RrYy: RY, Ry, rY, ry
– Possible gametes from RRyy: Ry (only)
– Results: RY, Ry, rY, ry x Ry, this creates offspring possibilities: RRYy, Rryy, RrYy, and Rryy.
2. For RrYY x Rryy:
– Possible gametes from RrYY: RY, Ry
– Possible gametes from Rryy: Ry, ry
– Results create combinations like RRYy, Rryy, and RrYy.
3. For RRYy x rrYY:
– Possible gametes from RRYy: RY, Ry
– Possible gametes from rrYY: rY
– Results would include RrYy.
4. For RRYy x rryy:
– Possible gametes from RRYy: RY, Ry
– Possible gametes from rryy: ry
– This would yield combinations like RrYy and Rry
