- In a population of 800 people, if p= 30%, what are the expected numbers of individuals with the genotypes TT, Tt, and tt? (Chp. 4) *Answers should only be the number. *H/W equation: p2+ 2pq + q² - 1 Genotype TT Genotype Tt- Genotype t7. In humans, Rh- blood is caused by the inheritance of two recessive alleles. Rh + blood is the result of inheriting at least one dominant allele for this blood type. The frequency of the recessive allele is 60%. What would the frequencies of the following be, assuming Harvey-Weinberg Equilibrium? ( * H/W equation: p²+ 2pq + q² = 1 Genotype DD = Dd = dd =8. Suppose that initially there are 22% with genotype TT, 16% have the Tt genotype, and 62% have the tt genotype. If the relative fitness of each of these genotypes is 3, 1, and 1, respectively, what is the genotype distribution in the next generation?
- A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotype. What is the allele frequency of A1? Answer to 2 decimal places.75. Under the conditions of the Hardy-Weinberg equilibrium, what term in the equilibrium equation represents the expected genotype frequency for homozygous recessive individuals? p2 2pq 2p+q p2+2pq+q2 q21. Assume Hardy-Weinberg equilibrium. In a population with 756 individuals, if genotype frequencies are equal to (AA) 36%, (Aa) 48%, and (aa) 16%, what is the probability of obtaining an (Aa) zygote? 36% 48% 60% 16%
- What genotypes, and in what frequencies, will be present in the offspring from the following matings? a. AABBaaBB b. AaBbaabb c. AaBBAABb d. AaBbAaBb6. You are studying the physiology of hypertension (high blood pressure) using the rat as a model system and wish to breed a strain of rat which has naturally high blood pressure. Systolic blood pressure is a quantitative trait with a continuous phenotypic distribution. It is measured as millimeters of mercury displaced in a blood pressure meter (mm Hg). You start with a base population of normal domestic rats, which has a mean systolic blood pressure of 120 mm Hg. You select the 10% of the rats which have the highest systolic blood pressure. The average systolic blood pressure value of these selected breeders is 140 mm Hg. You then interbreed the selected rats and measure the systolic blood pressure in their progeny. What would be the average systolic blood pressure in the progeny of the selected breeders if A. heritability = 0.5 ? B. heritability = 1.0 ? C. heritability = 0 ? D. In a second experiment, you go back to that same base population of domestic rats and select the 10% of…In a population, 12% of the babies are born with sickle-cell anaemia.

Attached earlobes are dominant over free hanging earlobes. Complete the Punnett Square for the following individuals: Mom-Bb and Dad=bb Provide the genotype and phenotype ratios using the Punnett square given below. Genotypes 5. When two alleles are observed independently in a phenotype is called multiple alleles. Human blood group ABO is a good example of multiple alleles. The three alleles are: IA, IB, i. Mother's blood type is AB (IAI³) and father's blood type is B (I³i). Provide the genotype and phenotype ratios using the Punnett square given below. Genotypes Phenotypes Genotypes Phenotypes 6. When the allele of a trait is found on X or Y chromosome, it becomes sex-linked. The results differ from males to females. One such example is of red green colorblindness.
