2. A true-breeding line peas with purple flowers, yellow pods, and green seeds (line A), is crossed to a true-breeding line with white flowers, green pods, and yellow seeds. The F1 all have purple flowers, green pods, and yellow seeds.

A typical line A individual would exhibit how many different pollen genotypes?____________
How many types of gametes can the F1 plants make?________________
How many of the F2 are expected to exhibit all three recessive traits? ________

Biology Problems: statistics (mean, variance, standard deviation, standard error), sequence of genes
47. Corn plants from a test plot are measured, and the distribution of heights at 10-cm intervals is recorded below.
(see chart in attached file)
Calculate (a) the mean height, (b) the variance (c) the standard deviation, and (d) standard error of the mean.
48. The genes dumpy wing (dp), clot eye (cl), and apterous wing (ap) are linked on chromosome 2 of Drosophila. In a series of two-point mapping crosses, the following genetic distance were determined:
