In $F_2$ generation,a phenotypic ratio of $1:1:1:1$ exhibits

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

In a plant,red fruit $(R)$ is dominant over yellow fruit $(r)$ and tallness $(T)$ is dominant over shortness $(t)$. If a plant with $RRTt$ genotype is crossed with a plant that is $rrtt$,what will be the phenotypic ratio of the offspring?

Define/Explain: Dihybrid cross.

If two pairs of genes are represented by $AA, Bb$,what are the possible gametic combinations after meiosis?

In Mendel's dihybrid cross,what is the probability of obtaining a plant that is heterozygous for both traits (in $/16$)?
