- 1. Certain flowers are either red (dominant) or white (rr). 91% of the flowers are red. Using the equations, calculate the frequency of the R allele. First you replace R and r for p and q. Thus we know that q2 = .09, because only the homozygous recessives will be white. *changed away from percentages to work the math more easily* What is the frequency of the R allele in this population? 2. In a coastal city in Nigeria, the incidence of Sickle-Cell disease is 4% of the population. Based on this information, what is the frequency of this allele in the population of that city? 3. In a given human population, only the "A" and "B" alleles are present in the ABO system; there are no individuals with type "O" blood or with O alleles in this particular population. If 200 people have type A blood, 75 have type AB blood, and 25 have type B blood, what are the alleleic frequencies of this population (i.e., what are p and q)? 4. An allele W, for white wool, is dominant over allele w, for…1. Calculate the genotype frequencies of a population of flowers where the frequency of the CR allele is 0.8 and the CW is 0.2.

In a population of mice, coat color is controlled by a single additive locus. BB mice are black, bb mice are white, and Bb mice are grey. The population is currently in HWE, with 1% of the mice having the white phenotype. Grey mice have twice as many offspring as black or white mice. What will be the frequency of the b allele in the next generation? The answer is supposed to be 0.16, can you explain how to get to this?

- 26. Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). What is the actual frequency of allele D? 0.819 0.181 0.435 0.3472. In humans, MN blood group is determined by a single gene with two codominant alleles, LM and LN. (This is a different blood group system from ABO). In a sample of 1000 Germans, there were 297 type MM 506 type MN 197 type NN A. Determine the frequencies of the LM allele and the LN allele in this population. B. Determine how many people there would be of each genotype if the population were in Hardy- Weinberg equilibrium and use the Chi-squared test to evaluate how well observed data fit expectations.1.) Consider flower color in a hypothetical population of 7,000 flowers, red flowers (4,000), blueflowers (2,000) are dominant over pink flowers. If there are 1,000 pink flowers, find thefollowing:a. Frequency of dominant (red flower) alleleb. Frequency of recessive (pink flower) allelec. Frequency of each genotype (homozygous dominant, homozygous recessive,heterozygous)d. Make a Punnett square and use the rule of multiplication.
