Assume that you have a garden and some pea plants have solid leaves and others have striped leaves. You conduct a series of crosses [(a) through (e)] and obtain the results given in the table. Define gene symbols and give the possible genotypes of the parents of each cross.

Cross		progeny
		solid	sriped
a	solid × sriped	55	60
b	solid ×solid	36	0
c	sriped × sriped	0	65
d	solid ×solid	92	30
e	solid × sriped	44	0

According to Mendel's model, because of the ________ of chromosomes during meiosis, all possible combinations of gametes will be formed in equal frequency.

In peas, gray seed color is dominant to white. For the purposes of this question, assume that Mendel crossed plants with gray seeds with each other and the following progeny were produced: 320 gray and 80 white.
a) What is the most probable genotype of each parent?
a) What genotypic and phenotypic ratios are expected in the progeny of such a cross?
