Lesson 3 Assignment

L. R. Schaeffer, March 1999

**Parameters:**

p = .34 |
for | |

q = .66 |
for | |

a = 1 |
||

d = .5, |

**Requirements:**

- 1.
- Calculate the expected values (using the above parameters) for
the population for the following items:
- (a)
- Genotypic frequencies.

- (b)
- Genotypic mean and variance.

- (c)
- Additive deviations and variance.

- (d)
- Dominance deviations and variance.

- 2.
- Sample 50 males and 50 females to produce 50 offspring from
a population with the above parameters. Each male and female are
mated once each to produce one offspring.
- (a)
- Calculate
*p*and*q*for the sample of 50 offspring.

- (b)
- Repeat requirement 1) using the sample estimates.

- (c)
- How well do the results compare to the expected values?

- 3.
- Suppose a locus has three (3) possible alleles with frequencies,
*p*,*q*, and*u*. Assume Hardy-Weinberg equilibrium and determine the formulas for genotypic frequencies, mean, and variance.
