Question
Chapter 13.2, Problem 1LO
Summary Introduction
To explain: The relationship between sex chromosomes and sex determination.
Introduction: All eukaryotic organisms contain chromosomes, and the number of chromosomes varies in different organisms. By studying the fruit flies Drosophila melanogaster, T. H. Morgan correlated sex chromosomes with the inheritance of a trait. During meiosis, a female Drosophila generates only X-bearing gametes, however, a male fly generates both Y-bearing and X-bearing gametes. A female fly (XX zygote) develops when an X sperm is involved in the fertilization and a male fly (XY zygote) develops when a Y sperm is involved in the fertilization.

Please help me to draw this by hand. In as much detail as possible, hand draw a schematic diagram of the hypothalamic-pituitary-gonad (HPG) axis in the human female. Be sure to include all the relevant structures and hormones. You must define all abbreviations the first time you use them. Please include (and explain) the feedback loops.

Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls? Use genetics lawsarrow_forward

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forward
