Vedclass · Answer

(A) Let the dominant allele for red flowers be represented by $R$ and the recessive allele for white flowers be represented by $r$.Since the red-flowered plant is homozygous,its genotype is $RR$.The white-flowered plant is recessive,so its genotype must be $rr$.When these two plants are crossed $(RR 	imes rr)$,the gametes produced by the red plant are $R$ and the gametes produced by the white plant are $r$.The resulting $F_1$ generation genotype is $Rr$.Since $R$ is dominant over $r$,all $F_1$ offspring will have the phenotype of red flowers.

If a homozygous red-flowered plant (dominant) is crossed with a white-flowered plant (recessive),the offspring will be:
