because if there isn't 46 in a human they can have medical problems like down syndrom
Humans and other organisms that reproduce sexually need to have half the normal number of chromosomes to make sure their offspring have the same number of chromosomes as they do - the father and mother each contribute half of their chromosomes (sperm and egg).
42
No, 29 chromosomes is not a normal number for a female. Typically, females have 46 chromosomes, consisting of two copies of 23 chromosomes.
what is the 2n chromosome number for a normal bug
If it is a human (somatic/non-sex) cell, it should function as normal because this is the correct number of chromosomes.
A human egg contains half the number of chromosomes found in normal body cells. Since normal body cells have 46 chromosomes, a human egg will contain 23 chromosomes. This reduction occurs through the process of meiosis, which produces gametes with a haploid number of chromosomes.
You will always have the same ammount of chromosomes, as this number never changes from birth to death. The normal number is 46, of which 23 are derived from the mother and 23 from the father.
The normal diploid number of chromosomes for humans is 46.
During meiosis, a cell with half the normal number of chromosomes (haploid) is generated to eventually form gametes (sperm or egg). When two haploid gametes fuse during fertilization, they restore the full set of chromosomes (diploid) in the zygote. This zygote then undergoes mitotic cell divisions to produce cells with the normal number of chromosomes.
A normal human body has 23 pairs of chromosomes, totaling 46 chromosomes, which are diploid in somatic (body) cells. Therefore, the number of haploid chromosomes in a normal human is 23. This haploid number is found in gametes (sperm and egg cells), which are produced through meiosis.
Haploid (?)
there are 46
