How many chromosomes do identical human twins have?
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
If a diploid organism has 11 chromosomes how many pairs of sister chromatids does each cell possess?
Assuming it is not in the anaphase stage then the chromosomes had 22 sister chromatids. 1 chromosome has 2 sister chromatids.
What is the number of chromosomes in a meiosis parent cell?
In humans, 46. 23 are passed from each parent to their child.
Is the chromosomes number related to complexity of the organism?
Different creatures have different numbers of chromosomes; chromosomes are always diploid, or found in matching pairs. The number of chromosomes is in no way related to the complexity of the organism. For instance, fruit flies have eight chromosomes, humans have forty-six, butterflies have 380, and ferns have a remarkable 1200 chromosomes.
How many genes are in human chromosomes?
23 from mom 23 from dad = 46 ^^^^^^^^^^^^ This answer is incorrect. The answer above answers the question: How many chromosomes are in the human genome? Chromosomes are made up of genes and in the human body there are 23 pairs of chromosomes, the human genome is theorized to have 20,000-25,000 genes So assuming (unrealistically) that every chromosome carried the same amount of genetic material (which they don't), then the answer would be 22,500/23 (for approximations sake).
Which cell has single set of chromosomes?
I'm assuming you mean 46 chromosomes. This is all cells. All cells have 46 chromosomes (the diploid number). Only gametes (sex cells, ie sperm and egg) have 23 chromosomes (sperm and egg meet to make a cell with 46 chromosomes). Cells dividing my meiosis (to produce gametes) have 92 chromosomes as they double up so they can half to get 2 cells with 46 chromosomes when they divide and therefore can produce the games with he haploid number (23)
How many chromosomes are in prophase1?
2N assuming it's a 2N individual.
How many chromosomes do identical human twins have?
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
If a diploid organism has 11 chromosomes how many pairs of sister chromatids does each cell possess?
Assuming it is not in the anaphase stage then the chromosomes had 22 sister chromatids. 1 chromosome has 2 sister chromatids.
What is the number of chromosomes in a meiosis parent cell?
In humans, 46. 23 are passed from each parent to their child.
How are a bird and crocodile homologouse?
Both species offer parental care to their offspring.
What does a chromosomes consists of?
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
How can you get the gender of a person through a drop of blood?
Assuming that the drop of blood had a white blood cell you could test the DNA for the sex chromosomes.
What is a relationship of chromosomes to chromatin?
I am assuming you know both chromosomes and chromatin are basically made up of DNA and proteins. They both reside in the nucleus of a cell. The chromosomes are not visible and neither are the chromatin. When mitosis occurs and the cell divides the chromosomes coil up and become chromatids (different again). These chromatids are the only one out of these three that is visible. To answer your question basically the relationship between chromosomes and chromatin can be summarised by the following sentence. <Chromosomes are made up of two chromatin joined together by a centreomere.> hope this helps :)
Can a sperm cell contain maternal chromosomes?
Absolutely (assuming you are referering to the maternal chromosomes of the man who is making the sperm) , the human set of chromosomes is composed of 46 pairs with half (23) coming from each parent. Mendel's laws suggest that each chromosome segregates and separates independently during mitosis (and subsequently meiosis) thus each gamete should contain a mixture of paternally and maternally derived chromosomes.
