Question
Chapter 41, Problem 2DAA
Summary Introduction
To explain: The time it took for the same number of sperms from men homozygous for deletion to appear in the camera’s view.
Concept introduction: The epididymis is part of the male reproductive system. Through the epididymis, the sperms travel from the testis to the vas deferens.

What is the genotype of the male offspring?
c)
A man and a woman have two sons. The woman is pregnant with a

The 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.
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…

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
- Consider two blood polymorphisms that humans have in addition to the ABO system. Two alleles LM and LN determine the M, N, and MN blood groups. The dominant allele R of a different gene causes a person to have the Rh+ (rhesus positive) phenotype, whereas the homozygote for r is Rh− (rhesus negative). Two men took a paternity dispute to court, each claiming three children to be his own. The blood groups of the men, the children, and their mother were as follows:From this evidence, can the paternity of the children be established?arrow_forwardhelppparrow_forwardWhat, if anything, does this experiment indicate about the validity of the pangenesis and the germ-plasm theoriesarrow_forward
- Semen from a promising bull is going to be used for artificial insemination. However, the owner is concern that the bull may carry a recessive lethal condition. Cows in the heard are 35% homozygous dominant and 65% are heterozygous for the lethal gene. Using these information calculate the number of cows that the owner has to inseminate in order to be 90% confident that the bull is not a carrier. (Assume that all cows inseminated will have healthy normal calves).arrow_forwardExplain this to me…..arrow_forwardA tortoiseshell cat, such as the cat pictured, is likely to be female. Why do tortoiseshell coats occur primarily in female cats? Testosterone suppresses the tortoiseshell gene in males, so tortoiseshell coats appear more often in females, who have less testosterone than males. Tortoiseshell coloring is an X-linked recessive trait, so females with two X chromosomes are more likely to express the trait than males. One of a female's two X chromosomes is randomly inactivated in each cell, so each cell may express different alleles. O The X chromosome is disabled in males, so a tortoiseshell coat, which is an X-linked recessive trait, does not occur in males.arrow_forward
- Males of many diploid species (like us) have X and Y sex chromosomes. They are hemizygous for most X- linked genes. Thus, males express most X-linked alleles, whether they are dominant or recessive in females. In the fruit fly Drosophila, it is common to achieve the equivalent of a test cross of X-linked genes in females by assessing the readily observed phenotypes of their male progeny. Since males do not receive X-linked genes from their father, sires of these crosses can be normal or wild-type flies. In fly genetics, it is conventional to name a gene after the mutant phenotype that enabled its discovery. Your challenge is to establish gene order and map distances between three X-linked genes in Drosophila. Each gene is represented by recessive mutant alleles that express rather distinctive phenotypes relative to their dominant wild-type alternative alleles. Flies expressing fruitless (f) are bisexual, lush (1) have a heightened responses to ethanol, and ken&barbie (kb) lack external…arrow_forwardIn humans color vision is X-linked, the gene for color vision is located on the X chromosome but is absent on the Y chromosome. Normal color vision (XN) is dominant over colorblindness (Xn). Suppose a colorblind man fathers the children of a woman with genotype XNXN. What is the genotype of the father? What proportion of daughters will be colorblind? What proportion of the sons will be colorblind?arrow_forwardThe direction of shell coiling in the snail Lymnaea peregra (discussed in the introduction to this chapter) results from genetic maternal effect. An autosomal allele for a right-handed, or dextral, shell (s+) is dominant over the allele for a left-handed, or sinistral, shell (s). A pet snail called Martha is sinistral and reproduces only as a female (the snails are hermaphroditic). Indicate which of the following statements are true and which are false. Explain your reasoning in each case. a. Martha’s genotype must be ss. b. Martha’s genotype cannot be s+ s+. c. All the offspring produced by Martha must be sinistral. d. At least some of the offspring produced by Martha must be sinistral. e. Martha’s mother must have been sinistral. f. All of Martha’s brothers must be sinistralarrow_forward
