Answer:

C) All offspring with at least one R will have red flowers.

Explanation:

All offspring with at least one R will have red flowers. R for red flowers represents the dominant trait. According to the law of dominance, if an offspring has Rr, the R, or red flower trait, masks the r, or white flower trait.

Answer:

Explanation: My first question is: what traits are these genotypes for? I was not 100% clear on that. Anyway, by performing a monohybrid cross with genotypes Rr and Rr, your resulting genotypes would be RR, Rr, Rr, and rr.

Basically, three offspring will be dominant in whatever the trait is and one will be recessive in that trait. So, approx. 75% of the offspring will express the dominant trait, while approx. 25% will express the recessive ( since there is no dominant allele present in the last genotype)
