Choose the best answer.

A woman with dark brown eyes (BB) and a green-eyed man (GG) give birth to a child whose eye color is brown with green tints because of ____________.

polyploidy

pleiotropy

triploidy

codominance

Answer 1

1. recombinant DNA — combining foreign DNA with host DNA produces recombinant DNA.
2. translation — tRNA anticodons match mRNA codons and bring amino acids during translation.
3. zygote — the fertilized egg formed when sperm and egg unite is a zygote.
4. codominance — both parental alleles are expressed, producing features of both (brown with green tints).
