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

Define the term: Filial progeny / $F_{1}$ generation.

In a cross between homozygous tall and dwarf pea plant,$F_2$ generation will show . . . . . . phenotypes.

In a cross,$45$ tall and $15$ dwarf plants are produced. The genotype of the parents is .....

From a cross $Aa BB \times aa BB$,what genotypic ratio will be obtained in the $F_1$ generation?

If two pea plants with red flowers,whose genotypes are unknown,are crossed,$75\%$ of the offspring have red flowers and $25\%$ have white flowers. The genotypes of the red-flowered parent plants must be:
