a. In a population, the frequency of the recessive homozygote is 0.39 for a certain trait. Calculate the percentage of individuals who are homozygous dominant, heterozygous, and homozygous recessive for this certain trait.

b. You find that the previous question’s population is 5,983 people. How many are phenotypically dominant? Recessive?

If 4% of a population has an autosomal recessive trait, what portion of the population are...

If 4% of a population has an autosomal recessive trait, what portion of the population are likely to be carriers? Assume that the population is large, and that the recessive trait doesn't affect fitness of the individual. List your answer as a percentage.

Allele frequency is the relative frequency of a certain allele type among a certain population. Suppose...

Allele frequency is the relative frequency of a certain allele type among a certain population. Suppose that within a certain area, the allele frequency of A, B and O are 0.2, 0.1, and 0.7, respectively. Suppose that when randomly picking up a person, the first allele type is independent of the second allele type regardless of the type. Calculate the following probabilities: • The probability for this person to have type O blood. • The probability for this person to...

The frequency of carriers for a rare autosomal recessive genetic condition is 0.04 in a population....

The frequency of carriers for a rare autosomal recessive genetic condition is 0.04 in a population. Assuming this population is in Hardy-Weinberg equilibrium, what is the allele frequency of the recessive allele? 0.2 0.4 0.64 0.8 Not enough information is provided.

Tay-Sachs disease is inherited as an autosomal recessive trait and is lethal in the homozygous recessive...

Tay-Sachs disease is inherited as an autosomal recessive trait and is lethal in the homozygous recessive condition at the age of 2years. A heterozygote marries a genotypically normal individual. What is the probability of having children that have Tay-Sachs?

Assume that a bi-allelic locus controls a (a) codominant trait, and (b) homozygous recessive lethal trait....

Assume that a bi-allelic locus controls a (a) codominant trait, and (b) homozygous recessive lethal trait. Show a Mendelian monohybrid intercross, and the expected phenotypic ratios in the F2 in each case.

Suppose colourblindness is an X-linked recessive trait, while Huntington's disease is an autosomal dominant trait. Assume...

Suppose colourblindness is an X-linked recessive trait, while Huntington's disease is an autosomal dominant trait. Assume both traits are rare. A colourblind man decides to have children with a women who is heterozygous for both genes. What is the probability that they will have a child that is colourblind and does not have Huntington's?

1. A severe disease that is inherited as an autosomal recessive trait is more likely to skip generations in a pedigree than an autosomal recessive trait that cuases a harmless phenotypic variant because a) all autosomal recessive traits skip generations b) a person with the harmless variant is less likely to reproduce than a person with the disease c) a person with an autosomal recessive disease is less likely to be well enough to reproduce than a person with a...

If an X-linked recessive trait was lethal to the development of an embryo, answer the following questions: A. could carrier females pass this trait to sons that survive child birth? B. could carrier females pass this trait to daughters that survive child birth? C. could fathers pass this trait to daughters that survive child birth? D. could fathers pass this trait to sons that survive child birth?

Albinism is a rare autosomal recessive trait in which there is a complete absence of melanin...

Albinism is a rare autosomal recessive trait in which there is a complete absence of melanin pigment in the skin, eyes, and hair. A normally pigmented woman whose parents are normal has a brother who is albino. She marries a normally pigmented man whose grandfather was albino. What is the probability their first child will be albino? I would like to see the problem worked out. Dont understand why it is 1/12. Thank you in advance

Perhaps you and/or your significant other is a carrier of a harmful recessive trait, such as cystic fibrosis. What would you do when considering having children? Would you hope for the best and ignore the situation, or would you see a genetic counselor or what? Select a genetic disorder from the "groups" list. Don't forget to sign up for it. Explain what type of genetic defect or disorder it is. Explain how this genetic anomaly occurs. Is it autosomal or...
