In a monohybrid cross,$120$ plants are obtained. The ratio of homozygous and heterozygous individuals shall be:

Normal maize has starchy seeds which remain smooth when dry. $A$ mutant form has sugary seeds which go crinkled when dry. When a mutant was crossed with a normal plant,an $F_1$ was produced which had smooth seeds. What would be the relative ratios of the different seed types,if the $F_1$ was allowed to self-pollinate?

Determine the number of possible types of gametes produced by an organism with the genotype $AABBCC$.

How many types of gametes can be produced by an individual with the genotype $AAbb$?

If in a garden pea plant,a cross is made between red flowered and white flowered plants,what will be the phenotypic ratio in the $F_2$ generation?

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?
