Identify the correct statement

Easy

A

Mendel’s simplest crosses involved only two pairs of contrasting traits.
B

During a cross of tall (true breeding variety) and dwarf pea plant, the dwarf trait that disappeared in the $F_{1}$ generation, never reappeared in the $F_{2}$ generation.
C

Pea plant shows natural cross pollination and self-pollination is very rare.
D

The results of Mendel’s monohybrid crosses were not sex dependent.

Solution

The results of Mendel’s monohybrid crosses were not sex dependent. In each cross, the $F_{1}$ and $F_{2}$ patterns of inheritance was similar regardless of which parental plant served as the source of pollen (sperm) and which served as the source of the ovum (egg). The crosses could be made either way—pollination of dwarf plants by tall plants, or vice versa. Crosses made in both these ways are called reciprocal crosses. Therefore, the results of Mendel’s monohybrid crosses were not sex dependent.
Mendel’s simplest crosses involved only one pair of contrasting traits.
During cross of tall (true breeding variety) and dwarf pea plant, the dwarf trait that disappeared in the $F_{1}$ generation, reappears in the $F_{2}$ generation.
Naturally flowers of pea plant undergo self-pollination.
