A person is born with XY chromosomes but physically and mentally presents as female until puberty.  What biological factors play a role?   A person with XX chromosomes are born with ambiguous genitals that resemble a penis, but they have internal ovaries.  What biological factors could be involved?   A person with XX chromosomes has a functional SRY gene on one of their X chromosomes.  How would you expect them to develop?   What role does birth order play in fetal development?

Describe why it is important that meiosis produces sex cells with half as many chromosomes as the parent cell.

A. Explain how mutation causes variation. Give examples. B. Explain how meiosis causes genetic variation in the gametes. (150 words for Task 1)

Usually, if a gene that affects a particular genetic trait is NOT located on a sex chromosome, then consequently (click all that apply) it is an autosomal gene. a diploid cell should have at least two copies of this gene during G1 phase. this gene will be absent from the genomes of gametes. this trait should appear with roughly equal frequency in males and females. this trait must be “dominant.”

Which of the following statements is true?   Women with endometriosis always have symptoms of the disease, even if they are only mild symptoms.   Patients under 25 years of age with endometriosis are often treated with surgical hysterectomy.   In endometriosis, endometrial tissue only grows on reproductive organs and cannot affect other structures in the pelvic or abdominal cavity.   About 1/3 of women with endometriosis struggle with infertility.

An individual is born XX. However, due to a rare crossing over event, one of the X chromosomes contains the SRY gene. We would predict that this individual would most likely develop (Choose all that apply): testes ovaries male external genitalia female external genitalia

In January 2009, Natalie Suleman successfully gave birth to octuplets and became known as Octomom. She already had 6 children, and all 14 of her children were conceived via in vitro fertilization (IVF). IVF involves removing eggs from the ovary, fertilizing them with sperm in a petri dish, and transferring the resulting embryos back into a uterus to develop. It is common for two or three embryos to be transferred into the uterus of a woman undergoing IVF to increase the chances of at least one of them surviving. When Ms. Suleman became pregnant with her octuplets, Dr. Kamrava had transferred 12 embryos. His license was revoked in 2011.Multiple eggs are required for IVF to produce functional embryos because some eggs are not fertilized or do not develop normally after fertilization. Which of the following hormones would be used to stimulate the ovaries to produce multiple eggs? Select one: a. Testosterone b. FSH c. Progesterone d. Estrogen

What defines our biological sex? What is the distinction between genetic and anatomical sexuality? Explain how chromosomes influence the internal and outward development of the sexual anatomy (hormones and structures). Is there always a correlation between genetic and anatomical sex? What is the reason, or why not? Describe a situation or disorder in which the internal and exterior sexual anatomy of a person do not match and explain how this would occur. Describe how a binary (male/female) model of sex does not reflect reality. What would a more accurate model look like?

Categorize each characteristic.

Identify which of the male and female external genitalia are homologous to each other.
