प्रश्न
In Mendel’s experiments, tall pea plants (T) are dominant over dwarf pea plants (t).
State Mendel’s Law of Dominance.
उत्तर
It states that recessive allele will always be masked by dominant aleles. Therefore cross between a homozygous dominant and homozygous recessive will always express the dominant phenotype, while still having a heterozygous genotype.
