Question

1. 3
2. 6
3. 8
4. 32
5. 64

Answer 1

Answer The different types of gaemetes that can be produced by a tall plant, with purple flowers, smooth pod shape, and Yellow, round peas that has a genotype (YyRtTTPPSs) are

C) 8

The number of gametes that will be formed will solely depend upon the heterozygous allele present .The gametes that will be formed will be determined by the 2^n(n raised to the power of 2), where n=heterozygous alleles present in the genotype. so here the heterozygous alleles are 3. so answer is 2^3=8.
