The Y chromosome is one of the two sex chromosomes in humans, determining male biological sex when paired with an X chromosome. It carries genes that are crucial for male sex determination and spermatogenesis, including the SRY gene, which triggers the development of testes. Unlike the X chromosome, the Y chromosome is much smaller and contains fewer genes, and it is passed from father to son, allowing for paternal lineage tracing. Additionally, the Y chromosome has a higher mutation rate, contributing to genetic diversity among male populations.

Is this sentence true or false. Genes on chromosomes determine whether a baby is a boy or girl?
True. The presence of certain genes on the sex chromosomes, specifically the Y chromosome, determines the sex of a baby. An individual with XY chromosomes will develop as a boy, while an individual with XX chromosomes will develop as a girl.
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".
What are the chromosomes that are not X or Y?
All chromosomes that are not either X or Y are called autosomes.
What is a true statement about Y chromosomes?
Y chromosomes are found only in males and are passed down from father to son. They play a crucial role in determining male sex characteristics and are responsible for the development of male reproductive organs. Due to their small size and unique genetic content, Y chromosomes are used in genetic testing to trace paternal lineages.
True or false Chromosomes other than sex chromosomes are autosomes.?
True. Autosomes are chromosomes that are not involved in determining sex. Humans have 22 pairs of autosomes and one pair of sex chromosomes.
Is it true that the x and y chromosomes are known as sex chromosomes because they determine an idvidual's sex?
Yes

Is it true that x and y are body chromosomes?
X and Y are copies of the chromosomes that determine gender. If someone has two x chromosomes they are female, while if they have one x and one y chromosome they are male. There is a rare disease where someone has one x and one y chromosome (known as XXY males) and these individuals display characteristics of both genders.
Which is the sex chromosome of lions?
You have pair of X chromosomes in case of females. You have a pair of X and Y chromosomes in case of male. This is true for all the mammals, most probably.
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).
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".
What are the chromosomes that are not X or Y?
All chromosomes that are not either X or Y are called autosomes.
Is it true that a person who inherits two X chromosomes will be a male?
Answer:This is not true. If you inherit two X chromosomes you will be a girl. A boy has a X and a Y chromosome. I don't know for sure, but I think so. After all, the numbers xs are greater than ysAnswer:No, it isn't. A person with XY chromosomes is male. Two X chromosomes is female.Answer:It is possible but they have to inherit a Y chromosomes. It called Klinefelter's syndrome (KS). KS has two X chromosomes and one Y chromosome. They can grow breast and have an ovary and have anger problems. Most men like this in up in prison.
Do animals have both X and Y chromosomes?
No, animals do not have both X and Y chromosomes. In most animals, males have XY chromosomes and females have XX chromosomes.

What are the names of the chromosomes that determine an individual's biological sex, commonly referred to as the x and y chromosomes?
The chromosomes that determine an individual's biological sex are called the X and Y chromosomes.
