In a pea plant, the yellow seed colour (Y) is dominant over the green seed colour (y) and smooth texture of seed (S) is dominant over wrinkled seed (s). The gametes produced by a heterozygous pea plant with yellow seed colour and smooth texture would be:
Correct answer: C. YS, Ys, yS, ys
- A. Yy, Ss
- B. Y, y, S, s
- C. YS, Ys, yS, ys
- D. Yy, YY, SS, ss
Explanation
C is the correct option. A gamete carries one allele from each gene.From a YySs plant:Seed color → Y or ySeed texture → S or sCombine one from each gene → YS, Ys, yS, ys

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
