A human with an XY chromosome pair appears female. What might explain this person's condition? O This person has an extra copy of the SRY gene. This person suffers from Turner syndrome. This person has a mutated SRY gene. This person suffers from Angelmansyndrome.
Biology. Men have XY (or YX) chromosomes and women have XX chromosomes. X-linked recessive genetic diseases (such as juvenile retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not defective. Represent a defective X chromosome with lowercase x, so a child with the xY or Yx pair of ...
Name the disorder with the following chromosome complement. (i) 22 pairs of autosomes + X X Y (ii) 22 pairs of autosomes + 21st chromosome + XY. Problem 1RQ: The correct sequence of levels forming the structural hierarchy is A. (a) organ, organ system,... Problem 2RQ: The structural and function unit of life is (a) a cell, (b) an organ, (c) the ...
The sex chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait Is attached to the X or Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-linked.

Flies and mammals use an XY chromosomal system of sex determination. Therefore, the mechanism to compensate for the higher gene dose on the two X-chromosomes in females compared to one X-chromosome in males is identical in both groups of animals!
Lab technicians compile karyotypes and then use a specific notation to characterize the karyotype. This notation includes the total number of chromosomes, the sex chromosomes, and any extra or missing autosomal chromosomes. For example, 47, XY, +18 indicates that the patient has 47 chromosomes, is a male, and has an extra autosomal chromosome ...
Predict the sexual phenotype of a person who is XY but whose Y chromosome carries a deletion of the SRY gene. Explain your predictio
X-chromosome inactivation in normal XX embryos occurs earlier in development than SRY production in normal XY embryos. When present on a translocation X chromosome, SRY is subject to inactivation. Formulate a hypothesis to explain why many XX individuals with a translocation X chromosome that includes the SRY gene are not completely sex ...
The 23rd pair of chromosomes comprise the special chromosomes X and Y. Females have a pair of X chromosomes (46 [23 pairs], XX), whereas males have one X and one Y chromosome (46, XY). The presence or absence of the Y chromosome determines whether an individual is biologically male or female.
