Chapter 41, Problem 4DAA
Summary Introduction
To explain: The percentage of sperm from a heterozygous man that would carry the del allele.
Concept introduction: The epididymis is a part of the male reproductive system. Through the epididymis, the sperm travel from the testis to the vas deferens.

- Human 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_forwardhelppparrow_forwardIf the mutation occurred in Jonathan's somatic cells when he was in his 30's, what type of alleles will be found in his sperm? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. b [+ 50% will contain the mutant Huntington allele, 50% will contain the wildtype allele. 25% will contain the mutant Huntington allele, 75% will contain the wildtype allele. Since Huntington's Disease is a dominant disorder, all of his sperm will contain mutant Huntingtin alleles. The condition will not appear in his gametes since he did not inherit it, but it arose as a new mutation in his body cells.arrow_forward
- 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.

- The dosage of X chromosome expression is equalized between male and female mammals. Think about the example of calico cats to answer the following questions. Use Xb to represent the allele for black fur, XB to represent the allele for orange fur. What genotype(s) of female cats is/are expected to have a calico coat? Is it possible to have a calico cat that is male? Explain.arrow_forwardWhich of the following is a FALSE statement? A) An individual with two X chromosomes and one Y chromosome has testes. B. The human female determines the sex of her offspring. (C) Genomic imprinting allows for differential expressions of an allele. D. Epigenetic changes can be passed on to a zygote.
