IV. MONOHYBRID, SEX-LINKED PROBLEMS 10. In humans, as well as in other primates, sex is determined by special sex chromosomes. An individual containing two X chromosomes is a female, while an individual possessing an X and a Y chromosome is a male. a. What is the genotype of your sex chromosomes? _________________________________________________________ b. In terms of sex chromosomes, what is the sex chromosomal genotype of the (ova)? _________________________________________________________ c.

Name Sex-linked traits are genetic char segments of DNA found on chromosomes that Sex-Linked Traits Senetic characteristics determined by genes located on sex chromosomes. Genies are and on chromosomes that carry information for protein production and that are sponsible for the inheritance of specific traits Genes exist in alternative forms called alleics. or a trail is inherited from each parent Like traits originating from genes on autosomes (non-se chromosomes), sex-linked to omosomes), sex-linked traits are passed from parents to offspring...

Question 1 1 pts Sex determination in mammals is due to the SRY region of the Y chromosome. An abnormality of this region could allow which of the following to have a male phenotype? O a person with an extra X chromosome Turner syndrome, 45, X O Down syndrome, 46, XX O a person with one normal and one shortened (deleted) X O translocation of SRY to an autosome of a 46, XX individual Question 2 1 pts What does...

Drosophila Genetics predictions exercise-L113 (25 pts.) Part I. Meiosis and Punnett Squares Remember, whenever you use Punnett Squares to solve genetics problems, be sure you are completing each of the following steps: 1) Identify the genotypes of the parents. 2) For the specific traits of interest, figure out what kinds of haploid gametes each parent can make. In each gamete, there should be one allele for each trait of interest. If there is more than one trait, make sure all...

What causes de la Chapelle syndrome (XX male syndrome)? A. It is caused by two nondisjunction events. The first occurs during meiosis in the mother resulting in an XX egg, and the second occurs during meiosis in the father resulting in a sperm with no X or Y chromosomes. When this sperm fertilizes the egg it results in XX male syndrome. B. SRY is intact but the body is unable to respond to the hormone androgen, which produces the female...

Questlon 21 3 p In Drosophila, nondisjunction during meiosis in the parent can result in flies with abnormal numbers of sex chromosomes. Flies with a single X and no Y are male, and those with XXY are female. Which of the following events could not give rise to a male with a single X in Drosophila? Nondisjunction at meiosis II in the female parent Nondisjunction at meiosis II in the male parent Nondisjunction at meiosis in the female parent All...
