Q: In a certain species of plants, violet flower color (V) is dominant over white flower color (v). If p = 0.4 and q = 0.6 in a population of 500 plants,I want you to explain why red is wrong and highlighted is right. ii. heterozygous (Vv):To calculate the number of individuals expected to be heterozygous (V), you would usethe equation: 2pqX N, where p is the frequency of the dominate allele (in this case, 0.4),q Is the frequency of the recessive allele (in this case, u.b), and N is the total populationsize (in this case, 500). So: 2 x 0.4 X 0.6 x 500 =12(individual expected to beheterozygous (VV)The number of heterozygous (Vv) plants in a population of 500 with p=0.4 and q = 0.6 can be calculatedusing the formula 2pq X 500. P and q are the frequencies of the dominate and recessive alleles in thepopulation. In this case, =2 X 0.4 X 0.6 = 0.48. so, the number of heterozygous plants would be,= 0.48 X 500 = 240.

3. a. Why are most populations not in Hardy Weinberg Equilibrium? b. There is an ancient village population of humans. We know very little about this population. How can we use genetics to determine if the societal system of the village was matrilocal or patrilocal? c. There was variation in a rat phenotype (coat color.) The coat colors ranged from dark color coats to light color coats. As the rats migrated into the basements of campus, the light color rats were more likely to be caught by the campus cat. Over time, the basement rat population shifted to entirely dark color coats. This is an example of what kind of selection? d. Explain how a genetic bottleneck could lead to higher susceptibility of a disease, such cancer, in that population.
The MN blood group is of interest to population geneticists because (a) people with genotype MN cannot receive blood transfusions from either MM or NN people (b) the MM, MN, and NN genotype frequencies can be observed directly and compared with calculated expected frequencies (c) the M allele is dominant to the N allele (d) people with the MN genotype exhibit frequency-dependent selection (e) people with the MN genotype exhibit heterozygote advantage

A researcher examines a locus, or marker, in which there is a particular C/T polymorphism in a population of interest. Let’s call this Locus 1. They obtain the following genotype counts in a sample of the population: CC:42, CT:16, TT:32. a) Calculate the genotype frequencies and the allele frequencies for Locus 1 in the sample.b) Calculate the observed heterozygosity (the frequency of heterozygotes) and the observed homozygosity (the total frequency of all homozygotes) in the sample. Ensure that these two frequencies add up to 1.

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.
