Dihybrid Cross Problem 1: Predicting combinations of alleles in gametes of plants heterozygous for two traits. A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. What will be the distribution of these two alleles in this plant's gametes? A. 50% of gametes are Sy: 50% of gametes are sY B. 25% of gametes are SY; 25% of gametes are Sy: 25% of gametes are sY; 25% of gametes are sy. C. 50% of gametes are sy: 50% of gametes are SY D. 100% of the gametes are SsYy E. 50% of gametes are SsYy: 50% of gametes are SSYY.

Dihybrid Cross
Problem 1: Predicting combinations of alleles in gametes of
plants heterozygous for two traits.
A pea plant is heterozygous for both seed shape and seed color. S is the allele
for the dominant, spherical shape characteristic; s is the allele for the
recessive, dented shape characteristic. Y is the allele for the dominant, yellow
color characteristic; y is the allele for the recessive, green color characteristic.
What will be the distribution of these two alleles in this plant's gametes?
A. 50% of gametes are Sy: 50% of gametes are sY
B. 25% of gametes are SY; 25% of gametes are Sy:
25% of gametes are sY; 25% of gametes are sy.
C. 50% of gametes are sy: 50% of gametes are SY
D. 100% of the gametes are SsYy
E. 50% of gametes are SsYy: 50% of gametes are SSYY.
