Question
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.

Hi! I would love to get some help on the box-and arrow model question! :)
A male individual who is XYSRY has the following genotype for the AMH gene on chromosome 19: AMH1 AMH2. The AMH1 allele codes for a protein that is capable of binding to the receptor for AMH. The AMH2 allele codes for a protein that is unable to bind with the receptor for AMH.
Based on your understanding of biology, what is the likely phenotype of this individual?
Humans have 23 pairs of chromosomes of which 22 pairs are autosomal and the 23rd pair is sex-linked.In a human female, the sex chromosome pair is represented as XX, whereas, in a human male, it is represented as XY.AMH is an anti-Mullerin hormone produced by the Sertoli cells in males and helps in the development of the sex organs. Each pair of chromosomes has a pair of genes called alleles at the same loci representing a single character. Each gene of an allele represents the expression of the character.A gene can either show expression or…
Butterflies have an X-Y sex-determination system that is different from that of flies or humans. Female butterflies may be either XY or X0, while butterflies with two or more X chromosomes are males. This photograph shows a tiger swallowtail gynandromorph, which is half male (left side) and half female (right side). Given that the first division of the zygote divides the embryo into the future right and left halves of the butterfly, propose a hypothesis that explains how nondisjunction during the first mitosis might have produced this unusual-looking butterfly.
Question is also in the picture.
Which findings support the fact that the presence of the Y-
chromosome rather than the lack of a second X-chromosome
determines the development of maleness in mammals?
A transgenic mouse with two X-chromosomes and the SRY gene from
the Y-chromosome develops male sex organs.
A human with an XXXY genotype (Klinefelter syndrome) is
phenotypically male.
A human with an XO genotype (Turner syndrome) is phenotypically
female.

- 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_forwardThe picture below represents a G1 cell from a newly discovered species that uses the X/Y sex determination system. Alleles for the different autosomal genes of interest are indicated on the chromosomes, and genes R and T are 16 cM apart. Red lines show maternal chromosomes, and blue lines show paternal chromosomes. Answer the following questions about this individual.d) Provide the genotype of the fertilizing male gamete that produced this individual. e) This individual can produce a pool of different gametes. List any TWO potential gametes that will occur at different frequencies. Give the alleles of each gamete contained within a set of brackets, and indicate the expected frequency (up to two decimals) at which that gamete would occur.arrow_forwardIn certain salamanders, the sex of a genetic female can be altered, changing her into a functional male; these salamanders are called sex reversed males. When a sex-reversed male is mated with a normal female, approximately 23 of the offspring are female and 13 are male. How is sex determined in these salamanders?

- The genotype of a dwarf mouse is Igf2 Igf2–. What is the genotype of its father who has normal body size? Indicate which allele is on the maternal chromosome and which allele is on the paternal chromosome for both dwarf mouse and its father.arrow_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_forwardTo determine whether radiation associated with the atomic bombings of Hiroshima and Nagasaki produced recessive germ-line mutations, scientists examined the sex ratio of the children of the survivors of the blasts.

- Albinism is caused by an autosomal recessive allele that interferes with skin pigmentation in mammals. Two normally pigmented human parents already have an albino boy. They plan to continue to have children until they get a girl. Some or all of this information is important for each of the questions below. a) What is the probability that their next child (currently unborn) will be a girl with albinism? Explain your reasoning. b) What is the probability their first female child will be albino? Explain your reasoning. c) The answer to part (b) is different (and, yes, the answer is different) from the answer to part (a). Explain why. (Hint: it has something to do with the underlined words.)arrow_forwardThe introduction to this chapter described the search for genes that determine pattern baldness in humans. In 1916, Dorothy Osborn suggested that pattern baldness is a sex-influenced trait that is dominant in males and recessive in females. More research suggested that pattern baldness is an X-linked recessive trait. Would you expect to see independent assortment between genetic markers on the X chromosome and pattern baldness if (a) pattern baldness is sexinfluenced and (b) if pattern baldness is X-linked recessive? Explain your answer.arrow_forwardBarr bodies are formed to adjust X chromosome dosage in species other than humans, such as Drosophila (fruit flies) and C. elegans (nematodes).
