Give differences : Homozygous and Heterozygous
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.
Mating of an organism to a double recessive in order to determine whether it is homozygous or heterozygous for a character under consideration, is called
Definitions / Explanation : Factors
When two individuals are similar in external appearance but differ in their genetic make up, they are called as
If two opposite alleles come together, one finding morphological expression masking the other, the fact is described as law of
Self pollination between $Tt$ and $Tt$ plants results into genotype ratio of
