How many chromosomes are there in the female nucleus of a pineapple pollen grain?
There are 50 chromosomes in both male and female pineapple pollen grain.
A human cell with 2 Barr bodies and no Y chromosome is from?
A female with 3 X chromosomes. (XXX) Two of the X chromosomes will be inactivated, leaving one functional X chromosome, 2 Barr bodies, and no Y chromosome.
What happens if a female with Turner Syndrome has the X chromosome inactivated?
Since someone with Turner's syndrome is X0 if you inactivated the X chromosome you would kill the person.
The 23rd pair of chromosomes that differ in males and females are?
During the process of meiosis that sex cells undergo, the chromosome set is halved from 46 to 23 chromosomes. This way, the combined chromosome sets of two sex cells after fertilization result in a full set again.
What combination of chromosomes is a female an a male?
Normal females have XX chromosomes and normal males have XY chromosomes. I believe there are two of each in a human body and the rest are autosomes.
How many chromosomes are there in the female nucleus of a pineapple pollen grain?
There are 50 chromosomes in both male and female pineapple pollen grain.
What is diffrnet from boys DNA and girls DNA?
This varies by species but in humans the female gender has cells with two x chromosomes of which one is randomly inactivated. This inactivated chromosome is referred to as the barr body. The male gender has cells with both an x chromosome and a small y chromosome. Source - Any recent biology textbook.
What is the x chromosome inactivation?
this is the process by which one of the two copies of the X-chromosomes present in female animals is inactivated
The number of chromosomes in a nucleus depends upon the female only?
False
How many chromosomes are there in the male nucleus in a pineapple pollen grain?
There are 50 chromosomes in both male and female pineapple pollen grain.
A human cell with 2 Barr bodies and no Y chromosome is from?
A female with 3 X chromosomes. (XXX) Two of the X chromosomes will be inactivated, leaving one functional X chromosome, 2 Barr bodies, and no Y chromosome.
What does a cells chromosomes contain?
Like all other cell types, chromosomes are found in nucleus only(head of the sperm). But the human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell during fertilization.
What happens if a female with Turner Syndrome has the X chromosome inactivated?
Since someone with Turner's syndrome is X0 if you inactivated the X chromosome you would kill the person.
What portion of the sperm cell contains the 23 chromosomes?
Like all other cell types, chromosomes are found in nucleus only(head of the sperm). But the human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell during fertilization.
Is 29 chromosomes normal for a female?
No, 29 chromosomes is not a normal number for a female. Typically, females have 46 chromosomes, consisting of two copies of 23 chromosomes.
When do chromosomes duplicate in a cells life?
When there joined with a male chromosomes and a female chromosomes
The 23rd pair of chromosomes that differ in males and females are?
During the process of meiosis that sex cells undergo, the chromosome set is halved from 46 to 23 chromosomes. This way, the combined chromosome sets of two sex cells after fertilization result in a full set again.
