In Mendel's dihybrid cross,what is the proportion of the dominant homozygous plants in the $F_2$ generation (in $/16$)?

What type of gametes will be formed by the genotype $RrYy$?

The genotypes of a plant variety were $TtHh, Tthh, ttHh$ and $tthh$,where $T =$ tallness and $H =$ hairy stem. Which one of the following crosses would produce progeny giving a phenotypic ratio approximately $1 : 1 : 1 : 1$?

When a tall plant with round seeds $(TTRR)$ is crossed with a dwarf plant with wrinkled seeds $(ttrr)$,the $F_1$ generation consists of tall plants with round seeds. How many types of gametes will the $F_1$ generation plant produce?

In a plant, tallness is dominant over dwarfness and red flower is dominant over white. Starting with the parents, work out a dihybrid cross. What is the standard dihybrid ratio? Do you think the values would deviate if the two genes in question are interacting with each other?

In Mendel's dihybrid cross,how many types of offspring were obtained in the $F_2$ generation that were different from the parental types?
