Red is dominant to white for flower color in a particular plant. If a red flowered plant (RR) is crossed with a white flowered plant (rr), what color will the offspring be?

Answer:

The offspring will all have red-colored flowers

Step-by-step explanation:

A dominant character is one that is always expressed when it is present.

A recessive character or trait is one that is only expressed in the absence of the dominant character. Thus, when the dominant and recessive character are both present in an organism, the recessive character will be hidden while the dominant character will be expressed.

According to Menedel's laws of inheritance, in the cross between the dominant (RR) red-flowered plant and the recessive (rr) white-flowered plant, the genotype of the offspring will be as follows:

RR x rr = Rr, Rr, Rr,Rr

The offspring are all heterozygous for flower color. However, since red flower color is dominant over white flower color, all the offspring produced will have red-colored flowers.
