Question
When a homozygote for one allele is crossed with a homozygote for another allele, all the progeny in the F1 generation are
Correct Answer
Option D is the correct answer.
Detailed Explanation
A cross between two homozygotes (e.g., AA x aa) will produce offspring that all have the same heterozygous genotype (Aa). They will all have the same genotype, and if one allele shows complete dominance, they will also share the same phenotype. The question asks for the genotype description, so 'heterozygote with the same genotypes' is most accurate.
Hint
What is the result of crossing a purebred dominant with a purebred recessive?
