How is the sex of a sexually reproducing dioecious mammal determine?

How is the sex of a sexually reproducing dioecious mammal determine? Please if you could explain clearly.

Solutions

Expert Solution

Dioecious = The presence of male and female reproductive structures in separate individuals
= Unisexual organisms

In mammals, sex is determined by the sex chromosomes i.e. allosomes.
In humans, there are two types of chromosomes.
1. Autosomes = Chromosomes that specify vegetative characters
2. Allosomes = Chromosomes that specify sexual characters

In humans,
XX = Homogametic = Females
XY = Heterogametic = Males

compare and contrast the biology of a sexually reproducing organism with another asexually reproducing organism. Or alternatively, find an organism that makes use of both forms of reproduction. For each organism, describe how their reproductive system works and speculate what environmental or social factors might influence this reproductive strategy. For at least one organism, you should also post a link to a popular science article/Wikipedia entry/ and/or video for your classmates to check out. (200-300 words)
