Vedclass · Answer

(A) Let the allele for red flowers be $R$ (dominant) and white flowers be $r$ (recessive).The heterozygous red-flowered plant has the genotype $Rr$.The pure-breeding red-flowered parent has the genotype $RR$.When these are crossed $(Rr 	imes RR)$:Gametes from $Rr$ are $R$ and $r$.Gametes from $RR$ are $R$ and $R$.The resulting genotypes in the offspring are $RR$ and $Rr$.Both $RR$ (homozygous dominant) and $Rr$ (heterozygous) express the red phenotype.Therefore,$100\%$ of the offspring will be red-flowered plants.

If a heterozygous red-flowered plant is crossed with its pure-breeding red-flowered parent,the offspring will show:
