Why x-chromosome are also called Barr body?
That is what random X chromosomes do in the female somatic cells. They form Barr bodies. This is a methylated X chromosome that effectively shuts this chromosome down, one per cell in a random manner. This is done by the body because too much protein product is detrimental to organisms.
Men have one of y?
The y chromosome. The chromosome pair that determine sex (gender) can have x and y chromosomes; men have one X and one Y chromosome, women have to X chromosomes.
Does the male or female pass colorblindess to the offspring?
It is on the X Chromosome (male have XY chromosome Females have XX Chromosome)
How you can distinguish y from the x sperm?
Size, generally. The X chromosome looks like an X and is smaller than the somatic chromosomes. The Y chromosome is a shrimp, comparatively, so it is always easy to spot.
Does the x or y chromones determin sex of children in the uterus?
Yes, except that it is chromosome, not chromones - whatever that may be!
Is an x chromosome and chromosome the same thing?
An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
What is the chromosome carried only by the sperm called?
The chromosome carried only by the sperm is called the Y chromosome, which determines the male gender when combined with the X chromosome from the egg during fertilization.
What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
In genetics what is the female sex chromosomes called?
X chromosome
What kind of chromosomes do females transmit to offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
What kind of chromosome do females transmit of offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
Does an x chromosome looks the same as a y chromosome?
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.
How is the X chromosome inactivated?
X chromosome inactivation is a process that occurs in female mammals where one of the X chromosomes in each cell is randomly inactivated. This ensures that both males and females have similar levels of X chromosome gene products. The inactivated X chromosome condenses into a structure called a Barr body.
What is the a pattern of inheritance in which certain characteristics carried on the X chromosome inherited from the mother are transmitted differently to her male and female offspring called?
This pattern of inheritance is called X-linked inheritance. It involves genes located on the X chromosome, leading to different inheritance patterns in males (who have one X chromosome) and females (who have two X chromosomes).
Is the x chromozone a female one or male one?
The X chromosome belongs to both males and females. However, females have two of the same kind of sex chromosome(XX), and are called the homogametic sex. Males have two distinct sex chromosomes (XY), and are called the hetrogametic sex.
In humans what are the chromosome pairs 1 through 22 called?
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.
What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
