What color are the flowers of the offspring shown in the Punnett Square?
Question 6 is based on the passage below
Hereditary traits are encoded in genes, which in turn are located on chromosomes Chromosomes come in pairs, and the pair of genes associated with a particular feature determines the characteristics of that trait. Often, there are several varieties of genes associated with a given trait. A gene is expressed when it is pure, meaning that it is expressed when both genes in a pair are alike A hybrid pattern occurs when two genes in a pair are different, and in cases of incomplete dominance the two traits will blend together to make a new trait.
Flower color in carnations follows an incomplete dominance pattern. When both genes in a pair are associated with the color red, then the plant produces red flowers. When both genes in a pair are associated with the color yellow, the plant produces yellow flowers. When a plant is hybrid and has one gene associated with the color red and another associated with the color yellow, then the two traits blend to produce orange flowers
Below is a Punnett Square showing the results when a carnation with yellow flowers and a carnation with red flowers are crossed to produce offspring. Punnett Squares predict the likelihood of specific gene combinations occurring.
- egg cell of female parent
\( \int \) sperm cell of male parent
CA gene for red color
Cr gene for yellow color
a. All are orange
b. All are red
c. Half are red and half are yellow.
d. All are yellow
