which of the following is true about a plant with the genotype aabbcc?

A plant with the genotype aabbcc is homozygous recessive at all three loci and will produce only one type of gamete: abc.

What aabbcc means

• Each gene pair (A/a, B/b, C/c) is homozygous recessive : aa, bb, and cc.

• Being homozygous at every locus means there is no heterozygosity anywhere in the genotype.

Gametes produced

• At the A locus, only allele a can go into gametes; at B, only b ; at C, only c.

• Therefore, this plant can produce only one kind of gamete: abc (not multiple combinations, because there is no heterozygous pair to segregate into different alleles).

Phenotypic implication

• If A, B, and C are dominant alleles and a, b, c are recessive, then a plant with aabbcc will show the triple recessive phenotype for all three traits.

• Crossing this plant with a fully dominant plant (AABBCC) produces F₁ offspring that are all AaBbCc and phenotypically dominant for all three traits.
