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. What are the possible sex chromosomal genotypes of a male's sperm cells?
_________________________________________________________
d. The gametes of which parent will always determine the sex of the offspring?
_________________________________________________________
Homework Answers
Answers:- a. Genotype of the sex chromosomes depends on whether you are male or female. If you are male the genotype will be XY and for female it XX.
b. In terms of sex chromosomes, the chromosomal genotype of ovum is X.
c. Possible sex chromosomal genotype of males is either X or Y.
d. The gametes of males will always determine the sex of offspring because it is heterogeneous ( Either X or Y) but for females it is always X type in gametes.

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...

1.a) How do we know that in humans the X chromosomes play no role in sex determination, while the Y chromosome causes maleness and its absence causes femaleness? c) How do we know that X chromosomal inactivation of either the paternal or maternal homolog is a random event during early development in mammalian females? d) How do we know that Drosophila utilizes a different sex-determination mechanism than mammals, even though it has the same sex-chromosome compositions in males and females?...
