In humans, the AR gene is located on the X chromosome. If a person who is XY has a complete deletion of the AR gene, do you think giving them testosterone injections during puberty would cause an increase in expression of male secondary sex characteristics compared to not receiving injections? Explain your answer.

Which gene on the Y chromosome triggers the development of male characteristics? What would happen if a male inherited a nonfunctional allele for this gene?
Why are males more prone to having x-linked recessive disorders?a. Because the y chromosome is smaller than the x chromosome. b. Because the y chromosome is weaker than the X chromosome c. Because there is a chromosome that will inhibit the eexpression of the defective gene. d. Because there is no other chromosome that will mask the other defective chromosome
Discuss the genetic determination of sex and the inheritance of X-linked genes in mammals.
Explain why X-linked recessive traits are often more common in males but X-linked dominant traits are often more common in females.
It is estimated that in about 1/150,000 births, an individual is born with 46 chromosomes, both an X and a Y chromosome, but is externally a phenotypic female at birth. A mutation in the gene for which protein is the most likely explanation for this condition? A. Chorionic gonadotropin B. Anti-Müllerian hormone receptor C. Testes determining factor D. Wolffian regression factor (WRF) E. Estrogen receptor β
Explain why X-linked recessive traits in humans are observed in more males than females.
If the gene is linked to the "Y" chromosome, women will not have the disorder. Why?
What must be true for a male individual to be a carrier of a Y-linked recessive allele? A. The gene has no other alleles. B. The gene is only expressed in females. C. The gene is silenced on the Y chromosome. D. The gene is also found on the X chromosome.
What is the gene in the human chromosome that determines the "maleness"?
Which of the following is NOT one of the events leading to male sex-determination in humans? The Wolffian ducts are degraded. TDF and SF1 stimulate transcription of SOX9. Testosterone is produced, which stimulates the development of male reproductive structures and other male secondary characteristics. Mullerian-Inhibiting Hormone (MIH) is produced. The SRY gene is expressed to produce Testes-Determining Factor (TDF).
In mammals, sex is determined bya. the SRY gene on the Y chromosome.b. having two copies of the X chromosome.c. having one copy of the X chromosome.d. both a and c
A husband and wife have normal vision, although both of the couple's fathers are red-green color-blind, an inherited X-linked recessive condition. What is the probability that the couple's first child will be a normal son? Enter your answer as a fraction or a whole number. Hint: Remember, humans determine sex via the XX = female, XY = male system. Think about the probability of having either a son or a daughter and the probability of having red - green color blindness.
