Question

Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?
The green trait is the dominant trait.
The offspring will inherit one allele from each parent.
The offspring will have both green and yellow seeds.
Each offspring will have a unique set of alleles.

Answer 1

"The offspring will inherit one allele from each parent."

Explanation: A true-breeding green (GG) crossed with true-breeding yellow (gg) gives F1 genotype Gg (heterozygous). Each offspring gets one allele from each parent and will show the dominant green phenotype; all F1s have the same genotype, not a mix of seed colors or unique allelic sets.
