How many chromosmes are found in the human somatic cell?
There are 23 pairs of chromosomes in each human somatic cell. 22 pairs are exactly the same in both males and females. In males there are XY sex chromosomes and in females these are XX.
How many chromosomes are needed to produce a new human being?
46 chromosomes are needed . 23 from the males sprem and 23 from the females egg.
Why are human females homogametic?
Human females are homogametic because they have two X chromosomes (XX), making them the heterogametic sex, while males have one X and one Y chromosome (XY). This is in contrast to species where males are homogametic and females are heterogametic, such as birds.
How many chromosomes are common to both males and females?
Both males and females have 22 pairs of autosomes and one pair of sex chromosomes. In females, the sex chromosomes are two X chromosomes (XX), while in males, the sex chromosomes are one X and one Y chromosome (XY). Therefore, one pair of the sex chromosomes is common to both males and females.
How many sex chromosomes do men have?
a human man has two pairs of 23 chromosomes, in total 46. there are cases where there is an extra chromosome in the 23rd spot of chromosomes in this case the man will have an extra chromosome, this is the cause of syndrome of down.
Contrast the sex chromosomes found in human females and human males?
Human females have two X chromosomes (XX) while human males have one X and one Y chromosome (XY). This difference in sex chromosomes determines biological sex and leads to different developmental pathways in males and females.
How many chromosmes are found in the human somatic cell?
There are 23 pairs of chromosomes in each human somatic cell. 22 pairs are exactly the same in both males and females. In males there are XY sex chromosomes and in females these are XX.
What is the 23rd pair of chromosomes that differ in males and females called?
The 23rd pair of chromosomes that differ in males and females is called the sex chromosomes. In females, the 23rd pair consists of two X chromosomes (XX), while in males, it consists of one X and one Y chromosome (XY).
Are x chromosomes all that females carry?
Yes. Females have 2 X chromosomes, while males have 1 X and 1 Y. in the human genome
The 22 pairs of chromosomes in human somatic cells that are the same in males and females are called?
Autosomes.
What Gene difference between human males and females?
One of the key genetic differences between human males and females is the presence of sex chromosomes. Males typically have one X and one Y chromosome (XY), while females have two X chromosomes (XX). This difference in sex chromosomes leads to differences in the expression of certain genes related to sex determination and secondary sexual characteristics.
The body cells of human males have what two chromosomes?
The body cells of most humans have 46 chromosomes, which can be arranged into 23 pairs. One chromosome in each pair comes from the mother and the other chromosome comes from the father. Of the 23 pairs, 22 pairs (the body chromosomes, or autosomes) are the same in males and females. The 23 rd pair, called the sex chromosomes, is different in males and females. In females, the sex chromosomes are the same and are called X chrosomes. In males, the sex chromosomes are different. One is an X chromosome (inherited from your mother or your father) and the other is a smaller chromosome called the Y chromosome (inherited from your father). So, the two chromosomes which are found in human males (but not human females) are the sex chromosomes, X and Y. See: http://biology.about.com/library/weekly/aa091103a.htm
Does human female have xx chromosomes?
Humans have 23 pairs of chromosomes In Females the last pair is XX In males the last pair is XY
How many chromosomes are needed to produce a new human being?
46 chromosomes are needed . 23 from the males sprem and 23 from the females egg.
Contrast the sex chromosomes found in human females with those in human males?
The dude is XY and the dudette (qurl) Is XX ! I think .
Why are human females homogametic?

How many chromosomes do females and males have?
