When an individual has both alleles of a contrasting character,it is said to be:

Two pea plants were subjected to cross-pollination. Of the $183$ plants produced in the next generation,$94$ plants were found to be tall and $89$ plants were found to be dwarf. The genotypes of the two parental plants are likely to be

$A$ pure tall garden pea plant is crossed with a pure dwarf garden pea plant. When the $F_1$ generation plants are self-pollinated,the resulting genotypic ratio is:

In a monohybrid cross,if you get a $3:1$ ratio,it denotes that:

$A$ cross was made between a pure tall and a pure dwarf pea plant to produce progeny. The progeny was self-pollinated. Find the ratio of the resulting true-breeding tall and dwarf plants.

When different alleles of the same gene are present in an individual,the individual is a
