Pure homozygous offspring in a dihybrid cross in the ${F_2}$ generation will be:

In Mendel's experiments with garden pea,round seed shape $(RR)$ was dominant over wrinkled seeds $(rr)$,and yellow cotyledon $(YY)$ was dominant over green cotyledon $(yy)$. What are the expected phenotypes of the $F_1$ generation when a homozygous round yellow plant $(RRYY)$ is crosseded with a homozygous wrinkled green plant $(rryy)$?

State the Law of Independent Assortment and explain how it is derived.

The following experiment is a dihybrid cross performed by Mendel. In which of the following are the green and wrinkled traits observed in the pea plants?

If the cells of an organism heterozygous for two pairs of characters,$Aa$ and $Bb$,undergo meiosis,what will be the genotypes of the gametes produced?

When a tall and red-flowered individual is crossed with a dwarf and white-flowered individual,the phenotype in the progeny is dwarf and white. What will be the genotype of the tall and red-flowered individual?
