In tomatoes, the red fruit color is completely dominant to yellow. Suppose a tomato plant homozygous for red is crossed with one homozygous for yellow and the progeny are allowed to self pollinate. What phenotypes do you predict in the F2 generation?
a) 3 red: 1 yellow
b) 9 red : 3 orange : 1 yellow
c) 1 red : 2 orange : 1 yellow
d) 1 red : 1 yellow
For each of the following statements, indicate whether the statement describes the P generation, F1 generation, or F2 generation.
The plants in the P generationF1 generationF2 generation were allowed to self-pollinate.
The plants in the P generationF1 generationF2 generation are true breeding.
After a cross, there are three times as many tall plants as there are short plants in the P generationF1 generationF2 generation.
. Flower color in lilies is controlled by an incomplete dominance pattern. Suppose you have two lily plants, both with orange flowers. You cross the two plants and are surprised to find that, half the offspring are orange, but ~25% are red and ~25% are yellow. You decide that you like the red flowers and would like to make more.
a) What cross would you perform to produce the most red flowered plants?
b) Your mother decides she would like some of the orange flowered lilies. Which cross would give you the most orange flowered plants?

G = yellow; g = green; R = round; r = wrinkled G Four different types of gametes are produced by a heterozygous individual when crossing over occurs, and two different types of gametes are produced when crossing over does not occur. What does this information reveal about crossng over? O Crossing over introduces variety by producing different combinations of alleles. O Crossing over reduces the incidence of DNA and chromosomal mutations. O Crossing over introduces variety in by creating types of genes. O Crossing over maintains the count of genes and the original alleles in both chromosomes.
