Giant plant growth is a recessive trait, normal-dominant. what plants should be spliced in order

Giant plant growth is a recessive trait, normal-dominant. what plants should be spliced in order to get offspring of uniform growth?

Let’s designate the gene that causes giant growth in oats as k, then the gene that causes normal growth of this plant will be K.

To obtain phenotypically homogeneous offspring, the following types of oats can be crossed:

Plants with gigantic growth. All of them will have the kk genotype and produce only one type of germ cells – k. Consequently, all offspring will be represented by giant oats with genotype kk homozygous for the recessive gene;

Plants of “clean lines” with normal growth, that is, oats homozygous for the dominant trait. It has the KK genotype and produces the same type of germ cells – K. All offspring have normal growth and a genotype similar to that of the parent plants – KK;

One is a plant with normal growth and a homozygous KK genotype, the other is a heterozygous hybrid oat with a normal growth and a Kk genotype. Despite the fact that hybrid oats produces two types of germ cells – K and k, all offspring will be phenotypically uniform: all plants will have normal growth. However, this phenotypically uniform offspring will be represented by two variants of genotypes: homozygous KK oats (50%) and heterozygous Kk oats (50%).
