Question

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.

Answer 1

C is definitely the answer

Answer 2

Answer:

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

Mendel's law of dominance states that the phenotype which is expressed in the heterozygous condition is the dominant trait and the allele responsible for that trait is a dominant allele. The other allele is termed as a recessive allele.

In addition, the dominant allele expresses itself over the recessive allele.

Thus, the individual with at least one dominant allele, that is, R in this case, will have the dominant trait, that is, red flowers.

So, the offsprings with RR and Rr genotype will have red flower phenotype.
