R = red flowers r = white flowers According to Mendel's law of dominance, which statement best describes the result of a cross between parents with genotypes Rr and Rr? A) Only RR offspring will have red flowers. B) Only Rr offspring will have red flowers. C) All offspring with at least one R will have red flowers. D) Because of the law of dominance, all offspring will have red flowers.

Hello!

I believe your answer is C. All offspring with at least one R will have red flowers.

Explanation: The capital letter means it will dominate. So if there is a R, then there will be a red flower.

Have a nice day.

The correct answer would be C) All offspring with at least one R will have red flowers.

The law of dominance states that the offsprings with heterozygous genotype will have the dominant trait in their phenotype, that is, only one copy of dominant allele is enough to produce the dominant trait in the phenotype.

Similarly, the offspring with at least one R (dominant allele) will have red flowers (dominant trait).

For example, the offspring produced by the cross of Rr and Rr would have three possible types of genotype; RR, Rr, and rr.

The offspring with RR and Rr will have red flowers due to the law of dominance while those with rr will have white flowers (recessive trait).
