haploid genotypes of all the gametes produced by a diploid individual | |
ABO blood type conferred by an individual gamete |
genotype of either the paternal or maternal chromosomal complement |
multilocus genotype of a chromosome or gamete |
2.) Which of the following statements regarding linkage disequilibrium is true?
Exists when D is less than zero, but not when it is greater than zero. |
Is reduced by sexual reproduction. |
Is increased by crossing-over during meiosis. |
Is increased by any random sampling error that happens to create or destroy certain chromosome genotypes but not others. |
Is reduced by selection that favors certain combinations of genotypes. 3.) Selection on multilocus genotypes in random-mating populations leads to linkage disequilibrium when _______________.

1) Which of these probabilities are NOT independent of eachother?
The probability that a student is a sophomore and has brownhair |
The probability that when you roll two dice, you will roll a 6before a 2 |
The probability that it will rain and the probability ofneeding an umbrella |
The probability that there will be heavy traffic on BaltimoreAve and the probability you will lose your cell phone 2) We are defining evolution as a "change in allele frequenciesover time". Ironically, the focus of this lab is the Hardy-Weinbergequilibrium - conditions that, if all met, will result in NOevolution occurring. Which of the following are among theconditions that must be met for the Hardy-Weinberg equilibrium toapply perfectly to a population?
