What are the possibilities of sex chromosomes?
boys must inherit the Y chromosomes from their father
Examine the chromosomes labeled x and y how does these two chromosomes compare?
Chromosomes X and Y do not truly make up a homologous pair. They act similarly in their roles, but they are not homologous (the same). The X chromosome in humans is much longer than the Y chromosome and also contains many more genes.
The genes on the x and y chromosomes are called what?
The genes carried on the X and Y chromosomes are called your "sex chromosomes".
Chromosomes other than X and Y?
Chromosomes that are not X or Y are called homologous chromosomes and autosomal chromosomes. The first 22 pairs of human chromosomes are autosomal.
What are the chromosomes that are not X or Y?
All chromosomes that are not either X or Y are called autosomes.
What are the possibilities of sex chromosomes?

How are boys boys and girls girls?
Gender is determined by chromosomes A male has an X and a Y chromosome. a female has 2 X chromosomes
How do boys chromosomes differ from girls?
Boys have one x chromosome and a y chromosome, whereas a girl has two x chromosomes.
What do X and Y chromosomes affect?
X and Y chromosoms determine whether or not an offspring is a male or female. Chromosomes come in pairs. Boys have an X and a Y chromosome pair; girls have an X and an X chromosome pair.

What are the X and Y chromosomes called?
The X and Y chromosomes are called the "Sex Chromosomes". Both the X and Y chromosome are part of the "sex-determining system" that helps determine the sex characteristics in humans. In the system, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY).
Do humans have matching pairs of chromosomes?
Yes we do. The chromosomes match each other perfectly, except the one that carries the sex information. One is an X and the other a Y, if a person is a boy or girl, they both having matching chromosomes, except the boys get short-changed and one of them is a bit shorter, and they call that the Y, that's why.
How do genes effect sexual development?
A body has 48 chromosomes, which are paired into 23 pairs. The 23rd, known as the the xy chromosomes, are also called the sex chromosomes. They determine whether you are a boy or a girl. Females have two chromosomes, xx, and boys have one x and one y chromosome. The y chromosome is kindof a deformity, an x missing a pice. y chromosomes cannot carry genetic information, so the x carries the traits for sexual development. one x or y is given y each parent. The mother always gives an x, the father can give x or y, thus being the determining factor for gender
How do autosomal chromosomes differ from chromosomes?
Autosomal chromosomes are all non-sex (X or Y) chromosomes.
