The cellular chromosome number is reduced from 2N to 1N.
The reduction of a gene pair to an allele during the formation of a gamete is called the principle of segregation, according to Mendel's law of segregation. This principle states that during gamete formation, the two alleles for a gene segregate from each other, with each gamete receiving only one allele.
A gamete is a specialized reproductive cell. There one sentence containing the word "gamete."
Yes, during meiosis, the process that produces gametes, homologous chromosomes from each parent segregate into different gametes in order to maintain genetic diversity in offspring. This means that gene pairs from one parent will not congregate in the same gamete.
Meiosis produces 4 genetically identical cells. However, in females, this only results in one gamete (called an ovum or egg) and 3 polar bodies which are smaller than the ovum.(In mammals one of the polar bodies usually disintergrates before division, in which case there would only be 2 polar bodies).
This is known as Mendel's law of segregation, where alleles of a gene separate during the formation of gametes, ensuring that each gamete carries only one allele. This process results in genetic variation in offspring due to the random assortment of alleles.
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.

The process is called meiosis, specifically during the formation of gametes, where alleles segregate. Each gamete receives one of the two possible alleles for a given gene due to the law of segregation, which states that allele pairs separate during gamete formation. This ensures genetic variation in offspring when gametes combine during fertilization.
A gamete containing a BB genotype will carry one B allele from each parent. This gamete will contribute one B allele to offspring during fertilization.
This extra chromosome in a gamete occurs as a result of a process called nondisjunction, where chromosomes fail to separate properly during meiosis. As a result, one gamete may end up with an extra chromosome, leading to conditions such as Down syndrome when that gamete contributes to fertilization. Nondisjunction can happen during either the first or second meiotic division and can affect any of the chromosomes.
Yes, during meiosis, the process that produces gametes, homologous chromosomes from each parent segregate into different gametes in order to maintain genetic diversity in offspring. This means that gene pairs from one parent will not congregate in the same gamete.
Four sperm are formed. One ova is produced.

Meiosis produces 4 genetically identical cells. However, in females, this only results in one gamete (called an ovum or egg) and 3 polar bodies which are smaller than the ovum.(In mammals one of the polar bodies usually disintergrates before division, in which case there would only be 2 polar bodies).
Mendel's observation of the segregation of alleles occurs during the gamete formation phase of meiosis, specifically in Meiosis I. During this phase, homologous chromosomes are separated into different gametes, ensuring that each gamete receives only one allele for each gene. This process underpins Mendel's Law of Segregation, which states that allele pairs separate during the formation of gametes.
In the given genotype, which consists of three identical homozygous alleles (AA), there is only one type of gamete that can be produced. Since all alleles are the same (A), the only gamete type formed would carry the A allele. Therefore, the number of gamete types is one.
