Option D

Solution

Hence, in plants the pair of alleles for height would be $TT$ , $Tt$ or $tt$ . Mendel also proposed that in a true breeding, tall or dwarf pea variety the allelic pair of genes for height are identical or homozygous, $TT$ and $tt$, respectively.

In other words the hybrids have $Tt$. Since these hybrids contain alleles which express contrasting traits, the plants are heterozygous.

When a true breeding pea plant that has yellow seeds is pollinated by a plant that has green seeds, all the $F_1$ plants have yellow seeds. This means that the allele for yellow is
