Provide all the possible gametes for the plant ttyyrr

The total number of possible combination of gametes formed through a particular genotype can be found by using the formula 2ⁿ, where n is the number of dissimilar or heterozygous allele pairs present in the given genotype.

For example, if the given genotype TtYyRR there are 2 allele pairs which are present in heterozygous condition.

So, possible combination of gametes would be 2² = 4.

All the possible combinations would be:
