- A refers to ”two or more alternative forms of a gene,” which are called alleles (III).
- B refers to ”cross of F1 progeny with homozygous recessive parent,” which is known as a test cross (IV).
- C refers to ”cross of F1 progeny with any of the parents,” typically called a back cross (I).
- D refers to ”number of chromosome sets in plant,” which is ploidy (II).
