How does the number of chromosome in a persons gametes compare with the numbers of chromosomes in the body cells?
There are half as many chromosomes in gametes than in normal body cells.
What else can I help you with?
Name the 2 human gametes and tell their chromosome number?
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
What is the number of chromosomes in a gemete?
Depends on what species is in questions - different species have different numbers of chromosomes in gametes.
Which pairs of cells do not have identical chromosomes numbers in a given species of plants?
In plants, the gametes (such as pollen and egg cells) have half the number of chromosomes as somatic cells. This means that the pairs of cells that do not have identical chromosome numbers in a plant species are the gametes and somatic cells. Gametes have half the number of chromosomes as somatic cells due to the process of meiosis that reduces the chromosome number by half during gamete formation.
Where do you usually find haploid numbers of chromosomes?
Haploid numbers of chromosomes are typically found in the gametes (sperm and egg cells) of an organism. These cells contain half the usual number of chromosomes, which is important for maintaining the correct chromosome number in the offspring after fertilization.
Does meiosis reduce chromosome numbers?
Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'. However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
The hybrid germ cells of a mule cannot undergo meiosis because?
Mules does not have even chromosome number. They have 63. During meiosis, chromosomes are paired up, one from the Mom and one from the Dad. Since mule does not have even chromosome number, pairing of homologous chromosomes are impossible, so meiosis is disrupted and no sex gametes are able to form.
Why do gametes have n numbers of chromosomes but not 2n?
Gametes are produced by the type of cell division called meiosis. During meiosis the number of chromosomes are halved. So if a cell starts off with 2n chromosomes and divides by meiosis the new cells will end up with n chromosomes.
If a diploid organism has a genome consisting of twenty two chromosomes its gametes will have how many chromosomes?
Gametes have half the number of chromosomes - therefore if the diploid number is 22, the gametes would have 11 chromosomes.
What happens if the gametes aren't haploid?
The whole purpose of reducing the gamete to contain half the number of normal chromosomes is so that normal chromosome numbers can be achieved again when the gametes fuse to form a zygote. If the gamete is not halved, polyploidy results. This is a generic term to describe having more than the normal number of chromosomes.
What is the significance of the chromosome number in gametes?
Chromosome numbers in gametes are always half that of normal cell. For example human cells have 46 chromosomes but a human gamete (sex cell e.g sperm/eggs) will have half that number which in this case will be 23. The number is chromosomes is halfed in gametes so that when the sperm meets the egg and the fuse to make a zygote that you get half the genetic material from your Mother and half from you Father, meaning you are not a clone.
What occurs during nondisjunction?
Nondisjunction is a chromosomal abnormality that results in the failure of homologous chromosomes or sister chromatids to separate properly during cell division. This can lead to an uneven distribution of chromosomes in daughter cells, causing genetic disorders or conditions such as Down syndrome.
If a cell has 14 chromosomes and undergoes meiosis how many chromosomes will each cell have?
The daughter cells will have 14 chromosomes, the same as the parent cell. Not only are the numbers of chromosomes the same, but they are also genetically identical to each other and the parent cell.
