# How many different gametes can a human produce?

## How many different gametes can a human produce?

Humans have 23 pairs of chromosomes. That means that one person could produce 223 different gametes.

## How many different combinations of chromosomes would there be in the gametes?

There are 8,324,608 possible combinations of 23 chromosome pairs. As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.

What is produced by meiosis?

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

### Where do mitosis and meiosis occur?

Because mitosis takes place throughout your lifetime and in multiple organs, it occurs more often than meiosis, which is limited to the reproductive organs during gamete formation.

### How many genetically different gametes can this cell form?

The number of different possible gametes produced by the diploid genotype (AaBbCcDdEe) is 2 x 2 x 2 x 2 x 2 = 32 (2 for each pair of heterozygous genes).

How many genetically different kinds of gametes and individual with genotype AaBb can produce?

four possible combinations
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.

#### How many genetically gametes can be produced solely by independent assortment in an organism where 2n 4?

Predict how many genetically different offspring could be produced by outcrossing two 2n=4 individuals (just account for independent assortment and not crossing over). Each parent has the potential to produce 4 genetically unique gametes via independent assortment.

#### How many genetically different gametes can be produced by independent assortment of chromosomes in a horse horses have 64 chromosomes?

8,388,608 different combinations
= 8,388,608 different combinations! 3. The horse (Equus caballus) has a diploid complement of 64 chromosomes. The donkey (Equus asinus) has 62 chromosomes.

Are the gametes produced by mitosis or meiosis?

Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. The single zygote cell never grows or divides my mitosis. It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.

## What type of cells are produced by meiosis and mitosis?

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

## Are gametes formed through mitosis?

Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.
