Question
A heterozygous tall plant of pea is crossed with a dwarf plant of pea.
Calculate the phenotypic ratio of the progeny.
Solution
When a heterozygous tall plant of pea (Tt) is crossed with a dwarf plant of pea (tt), it can be represented as follows;
In this cross, 50% of offspring are tall and 50% are dwarf.
Thus, the phenotypic ratio of the progeny = 1 (Tall) : 1 (Dwarf)
