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?

$A, B, D$ are three independently assorting genes with their recessive alleles $a, b, d$,respectively. $A$ cross was made between individuals of $Aa bb DD$ genotype with $aa bb dd$. Find out the types of genotypes of the offspring produced.

In Mendel's dihybrid cross experiment,when $F_1$ generation plants are self-pollinated,what is the proportion of each type of gamete produced (in $\%$)?

What will be the phenotypic ratio of the offspring obtained from a cross between $Aabb$ and $Ccdd$?

From a mating of two dihybrid individuals $(AaBb \times AaBb)$,how many of the $16$ possible zygote combinations would be expected to contain only two dominant genes?

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 in the $F_{2}$-generation of the cross $RRYY \times rryy$?
