What does this diagram indicate?

Describe one gene inheritance.

If a homozygous red-flowered plant (dominant) is crossed with a white-flowered plant (recessive),the offspring will 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

In garden pea,round shape of seeds is dominant over wrinkled shape. $A$ pea plant heterozygous for round shape of seed is selfed and $1600$ seeds produced during the cross are subsequently germinated. How many seedlings would have the parental phenotype?

$A$ heterozygous tall pea plant was crossed with a dwarf pea plant. The progeny of the cross shows . . . . . . .
