For these experiment assume allele A = red, allele a = white . There are three flower colors (phenotypes and genotypes) for this species where AA=red, Aa = pink, aa = white. • A population of Four O-Clocks is in Hardy-Weinberg equilibrium and no evolutionary forces are acting on the population. Bees are introduced into the population. Individual bees only visit a single color of flower so that red flowers only mate with red flowers, pink with pink, and white with white. The simulator we have been using doesn't have "positive assortative mating" as an option, but if it did (in addition to the other parameters) which parameters should be changed to model this problem? Select all that need to be changed. O Selection O Migration O Mutation O Finite Population (i.e. population size) O Assortative Mating

Bees are introduced into the population. Individual bees only visit a single color of flower so that red flowers only mate with red flowers, pink with pink, and white with white. What will happen to the genotype frequencies in the next generation? O The proportion of reds and whites will increase over pinks. O The population will remain in Hardy-Weinberg equilibrium. O The proportion of pinks will increase over reds and whites. The proportion of reds will increase over pinks and whites.
Tongue rolling ability is conferred by the presence of a dominant R allele. Nonrollers are genotype rr. A class of GN 311 students consists of 289 rollers and 29 nonrollers. Assume that this population is at Hardy-Weinberg equilibrium for this locus. P What is the frequency of the R allele? What is the frequency of the r allele? • How many people in the class are expected to be heterozygous for this locus?
Among a particular population of 100 plants, red flowers are dominant and yellow flowers are recessive. F is the dominant allele and f is the recessive allele. 40 plants are homozygous dominant • 44 plants are heterozygous 16 plants are homozygous recessive Use the Hardy-Weinberg equation to calculate the equilibrium frequencies of each genotype
In this version of the simulation (500 population size; 500 carrying capacity), all fish are equally likely (though not 100% likely) to survive and reproduce. There are no mutations, nor are there any entering or leaving the population. When they reproduce, they choose a mate from the pool at random and produce ten offspring by chance with the probability of the offspring’s genotypes determined by the punnett square. What caused the allele frequencies to change and vary in the trials? (ex attached).
Hardy-Weinberg Calculations Australian blood bankers said they calculated the gene frequency of the new antigen found in a native Australian as being 0.22. This antigen is co-dominant and is called Gia. What is the frequency of homozygous Gia? What is the frequency of heterozygous people? When the allele Gib is found, what would the frequency be for those that are homozygous for Gib? please explain step by step, thank you

Recall that the Hardy-Weinberg model makes the following assumptions: No mutations Extremely large population No gene flow No selection You score flower colour in a very large natural population where flower colour is a co-dominant trait where white and red are homozygotes (CWCW and CRCR) and pink are heterozygotes (CWCR). Taking your observed phenotypes and genotypes, you apply the Hardy-Weinberg principle and find an excess of homozygous individuals (that is, individuals with either white or red flowers). Give two plausible explanations for this excess of homozygotes in the natural population.
> Within a certain population, there are exactly 2 alleles at the T locus: T and t. Among the entire population, 30% of the alleles are T. If this population is in Hardy Weinberg equilibrium, what proportions (or percentages, however, you want to express it) will be TT, Tt, and tt? Show work. In a population, there are 75 TT individuals, 25 Tt individuals, and 250 tt individuals. What are the frequencies of T and t? Show work. What are the "expected" numbers of each genotype? Show work. Ís this population in Hardy Weinberg equilibrium? (don't do Chi², just compare your answer in a) b) c) part b io actual and it should be obvious.) ) Assume that, in a population of deer, two alleles exist for eye color. BB deer have blue eyes, Bb deer have purple eyes, and bb deer have red eyes. Out of a population of 1000 deer, 490 have blue eyes. You took notes on the amount of red and purple eyed deer, but your notebook fell in the mud and those numbers are obscured. However, if the population is in…

A population of wild flowers was scored for flower color. There were 493 blue (BB) plants, 1633 violet (BR) plants, and 859 red (RR) plants. Remember to keep 4 decimal digits on all frequencies. • What is the frequency of the blue (B) allele? • What is the frequency of the red (R) allele? What is the expected number of blue (BB) plants? • What is the expected number of violet (BR) plants? • What is the expected number of red(RR) plants? Keeping all decimal digits during your calculations and rounding your answer to 3 decimal digits, what is the calculated chi-square value? What is the number for the degrees of freedom? What is the critical value? Round to two decimal places. What is your conclusion from the chi-square test?
According to Hamilton's Rule, in which scenario is selection for cooperative breeding expected to be the strongest? but lose the chance to have Helpers raise and increase the survival and reproduction of of their own offspring. O 100 additional 2nd cousins twice removed to whom they are 0.00781 (0.781%) genetically related; 2 of their own offspring. 60 additional 1st cousins once-removed to whom they are 0.0625 (6.25%) genetically related; 1 of their own offspring. O 50 additional grandnieces/nephews to whom they are 0.125 (12.5%) genetically related; 2 of their own offspring. None of the three scenarios are likely to result in the evolution of cooperative breeding according to Hamilton's Rule.
