Chapter 19, Problem 8CT
A man is homozygous dominant for ten different genes that assort independently. How many genotypically different types of sperm could he produce? A woman is homozygous recessive for eight of these genes and is heterozygous for the other two. How many genotypically different types of eggs could she produce? What can you conclude about the relationship between the number of different gametes possible and the number of heterozygous and homozygous gene pairs that are present?

A heterozygous free-lobed man is mated to a heterozygous free-lobed woman. What are the genotypes and phenotypes of their possible offspring?
Earlobes can be attached to the face or non-attached. An attached earlobe is a recessive trait. A female with attached earlobes (Il) has a child with a man with non-attached earlobes. He is heterozygous for this trait.
Questions:
a. What are the possible genotypes of the egg the woman can produce?
b. What are the possible genotypes of the sperm the man can produce?
c. What is the genotype ratio for the offspring?
d. What is the phenotype ratio for the offspring?
e. What is the couple's chance of having a child with attached earlobes?
In fruit flies, the allele for normal wings (V) is dominant to the allele for short wings (v). Suppose two fruit flies heterozygous for the trait are mated.
What is the male fruit fly’s genotype and the female fruit fly’s genotype?
What is the male fruit fly’s phenotype and the female fruit fly’s phenotype?
What will be the genotypic ratio of the F1 generation?
What will be the phenotypic ration of the F1 generation?

- During the process of Meiosis an individual's alleles for each trait are independently sorted to make unique gametes. A person is heterozygous for the Freckles phenotype (Ff) and also heterozygous for the PTC-tasting phenotype (Tt). This person's genotype for these two traits is represented as FfTt. A) How many unique gametes could be produced by this individual if you consider these two traits? B) List the different allele combinations that could result.arrow_forwardThe probability that both alleles in the offspring are type A is the product of the probability that the allele from the pollen is A and the probability that the allele from the ovule is A (we will derive this in Section 6.5). What is the probability that the offspring of a homozygous parent is homozygous? What is the probability that the offspring of a homozygous parent is heterozygous?arrow_forwardWidow’s Peak is dominant over straight hairline. Free earlobes are dominant over-attached.

- 1. If one parent is Tt, what alleles can they pass on to an offspring? (we're talking about a parent producing a gamete, right?) 2. If one parent is TT and the other parent is Tt, what are the possible offspring (These are zygotes, right?) --This is where it gets confusing so make sure to read over Larsen's explanation, and my explanation in the lecture video. The first two questions were super simple, but they were designed to orient your thinking for a dihybrid cross 3. If one parent is TtRr, what alleles can they pass on to an offspring? (what do their gametes look like in terms of letters?) 4. Same as #3, but with different letters. If one parent is TTrr, what alleles can the pass on to an offspring?arrow_forwardHuman sex chromosomes are XX for females and XY for males. a. With respect to an X-linked gene, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele? c. If a female is heterozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele?arrow_forwardHuman females have two X chromosomes (XX); males have one X and one Y chromosome (XY). a. With respect to X-linked alleles, how many different types of gametes can a male produce? b.

- Suppose the mating had occurred between homozygous recessive male for a disease and a normal female known to be heterozygous. What would the probabilities be for the following outcomes? 3 offspring in the following order: normal, with disease, normal Use the factorial equation n!/x!(n-y)! * (p)x (q)n-x n = number of events (offspring) x = number of normal / dominant offspring n-y =total - number of abnormal / recessive offspring p = probability of producing a normal/dom q = probability of producing an abnormal/recarrow_forwardA husband and wife have normal vision, although both of the couple's fathers are red-green color-blind, an inherited X-linked recessive condition. What is the probability that the couple's first child will be a normal son? Enter your answer as a fraction or a whole number. Hint: Remember, humans determine sex via the XX = female, XY = male system. Think about the probability of having either a son or a daughter and the probability of having red - green color blindness.arrow_forwardDraw a Punnett square for a female who is a heterozygote and a male who is a dominant homozygotes.
