# How many chromosomes will the gamete of an organism with 16 total chromosomes have?

Contents

An organism has 16 chromosomes in diploid cells. The number of chromosomes present in the haploid cells produced by this organism will be 8.

## How many chromosomes are in a gamete?

In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number.

## What does 2n 16 mean?

2n = 16, n is the haploid number of chromosomes. 2n = 16, it means n = 8. The haploid number of chromosomes is 8. The sperm and egg cells have a haploid number of chromosomes. Thus, it will have 8 chromosomes in their cell.

## Does a gamete have 2 chromosomes?

The homologous chromosomes are separated when gametes are formed. Therefore, gametes have only 23 chromosomes, not 23 pairs.

## Why are there only 23 chromosomes in gametes?

Fertilisation. Gametes have half the total number of chromosomes that the organism needs to develop and are referred to as haploid . For example, humans need 46 chromosomes to develop, therefore a human gamete has 23 chromosomes.

## How many possible gametes are there?

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).

## What is an example of a gamete?

In short a gamete is an egg cell (female gamete) or a sperm (male gamete). … This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell).

## Which is true about an organism with 2n 16 chromosomes?

The number of chromosomal sets is denoted by the letter n. When a species’ chromosome number is 2n = 16, that means the diploid cell has 16 chromosomes. A diploid cell has two sets of chromosomes (2n). A haploid cell (gamete) has only one set of chromosomes, a total of eight.

## How many homologous pairs are in 2n 16?

Question: Which of the following is true of an organism that has a chromosome number of 2n = 16? a) Each diploid cell has 8 homologous chromosomes.

## How do you count the number of chromosomes?

It is very simple to count number of DNA molecules or chromosome during different stages of cell cycle. Rule of thumb: The number of chromosome = count the number of functional centromere. The number of DNA molecule= count the number of chromatids.

## Are gametes cells?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

THIS IS IMPORTANT:  What's the advantage of having 23 pairs of chromosomes instead of just one pair?

## Is gametes 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.

## How many chromosomes does an individual human gametes have?

Human gametes have 23 chromosomes, one each of 23 unique chromosomes, one of which is a sex chromosome. This is the n or haploid condition.

## Why are there 46 chromosomes and not 23?

This is because our chromosomes exist in matching pairs – with one chromosome of each pair being inherited from each biological parent. Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23. Of the 23 pairs, 22 are known as autosomes.

## How do gametes form?

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

## Why do gametes have haploid number of chromosomes?

Gametes are produced as a result of meiosis during which the chromosome number is reduced to half and each daughter cell receives half the set of chromosomes. Therefore, gametes have a haploid number of chromosomes.
