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.

Humans have two different sex chromosomes, X and Y. Figure 4 below shows the inheritance of sex in humans. Figure 4 Mother Father XX XX Y XY XY a) Copy the diagram into your answer booklet and draw a circle on the part of Figure 4 that shows an egg cell. b) What is the genotype of the male offspring? c) A man and a woman have two sons. The woman is pregnant with a third child. What is the chance that this child will also be a boy?
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…
