Which of the following statements is true of the Hardy-Weinberg equation (p² + 2pq + q² = 1)? a. The "p" represents the frequency of the recessive allele for a specific trait in a population. b. In order to use the equation, you have to know all of the genotype frequencies first. c. The equation allows you to discover the genotype frequencies if you know the phenotype frequencies. d. The equation can only tell you if the population is in equilibrium.

Step 1
The Hardy-Weinberg equation is p² + 2pq + q² = 1. Here, "p" represents the frequency of the dominant allele, and "q" represents the frequency of the recessive allele in a population. The terms p², 2pq, and q² represent the frequencies of the homozygous dominant, Show more…

This Hardy-Weinberg equation, p + q = 1, means ___________________. A. The sum of genotype frequencies equals to 1. B. The sum of allele frequencies equals to 1. C. A population is under genetic equilibrium. D. Population size of the population remains constant over generations. 2. A locus has two alleles with allele frequencies p and q. If a population is not under Hardy-Weinberg equilibrium, p + q may not equal to 1. True or False?

Which statement about allele frequencies is not true? a. The sum of all allele frequencies at a locus is always 1 b. If there are two alleles at a locus and we know the frequency of one of them, we can obtain the frequency of the other by subtraction. c. If an allele is missing from a population, its frequency in that population is 0 . d. If two populations have the same allele frequencies at a locus, they must have the same proportion of homozygotes at that locus. e. If there is only one allele at a locus, its frequency is 1
Which of the following definitions is FALSE? (A) $\quad$ Penetrance-the percentage of individuals in the population carrying the allele who actually express the phenotype associated with it (B) $\quad$ Expressivity-the percentage of individuals in the population carrying the allele who do not express the phenotype associated with it (C) $\quad$ Incomplete dominance-occurs when the phenotype of the heterozygote is an intermediate of the phenotypes of the homozygotes (D) $\quad$ Codominance-occurs when multiple alleles exist for a given gene and more than one of them is dominant
