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.
If at a tall plant is crossed with a dwarf plant and obtained progeny is half tall and half dwarf plants. Then the genotype of progeny will be
Which of the following terms represent a pair of contrasting characters?
The alleles are
A test cross is carried out to
If two opposite alleles come together, one finding morphological expression masking the other, the fact is described as law of
