What is the number of chromosomes in a gamete drosophila?
A gamete of Drosophila has 2n chromosomes, which is the haploid number. Drosophila, like most organisms, has a diploid number of chromosomes in its somatic cells. During meiosis, gametes are produced with half the number of chromosomes to maintain the chromosome number in the species.
How can nondisjunction in meiosis result in a diploid gamete?
If all of the chromosomes fail to separate in meiosis, then nondisjunction can result in a diploid gamete. This is a type of chromosomal mutation. In animals, a zygote produced from the union of a mutated diploid gamete and a normal haploid gamete will have triploidy, which is lethal. In plants, this is not necessarily lethal.
What type of cell does meiosis make?
Meiosis produces gamete cells, such as sperm and egg cells, which are haploid cells with half the number of chromosomes as a normal body cell.
An organism that reproduces sexually has a diploid number of 30 How many chromosomes will a gamete of this organism have?
A gamete has half the diploid number of chromosomes, so in this case, the gamete would have 15 chromosomes.
How many chromosomes are in a gamete?
Human gametes have 23 chromosomes. (In cases of abnormality there may be a different number of chromosomes in a gamete).
The number of chromosomes in a gamete of an organism is its what?
D. Be produced by meiosis
How many chromosomes would be present in a zebra gamete after meiosis the zebra has 50 chromosomes in its diploid cells?
A gamete has half the number of chromosomes of the somatic (diploid) cell. Therefore a zebra gamete would have 25 chromosomes if 50 is the diploid number.
What type of cellular reproduction reduces the number of chromosomes in each gamete?
meiosis :)
How does a haploid gamete get a 1n number of chromosomes and a 1n amount of DNA?
By the process of meiosis.

In animals, a zygote produced from the union of a mutated diploid gamete and a normal haploid gamete will have triploidy, which is lethal. In plants, this is not necessarily lethal.
Why does the formation of gametes involve meiosis?
Meiosis is the process of making a cell that has the same number of chromosomes as the parents. In order to keep the same number, they each make gametes which have half their own number of chromosomes. When one gamete, sperm, fertilizes the other gamete, the egg, they join their number of chromosomes together to make an offspring with the same number as the parents have. If they did not do this by meiosis, then very soon, we would have animals which huge numbers of chromosomes.
During meiosis twin chromosomes split apart and move to the?
opposite poles of the cell, ensuring that each gamete receives only one copy of each chromosome. This is important for maintaining the correct number of chromosomes in the offspring.
What process of nuclear division in which the number of chromosomes in certain cells is halved during gamete formation?
Meiosis is the process of nuclear division in which the number of chromosomes in certain cells is halved during gamete formation. This reduction in chromosome number ensures that when two gametes combine during fertilization, the resulting zygote will have the correct number of chromosomes.
What is gamete for heredity?
if you are asking what one is, a gamete is a sex cell that has half the number the number of chromosomes from one parent. during fertilization, two gamete(one from each parent) combine. they are formed during meiosis.
What are the number of chromosomes in the human gamete?
There are 23 chromosomes in a human gamete
If a cell with 40 chromosomes undergoes mitosis each of the daughter cells will have chromosomes.?
Meiosis results in gametes that have half the number of chromosomes of other cells. A gamete carries one of each pair of homologous chromosomes. Their are 46 chromosoes in Meiosis I and 23 in Meiosis II.
