Which genotypes complete the following Punnett square?

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
