## How many possible combinations of maternal and paternal chromosomes are there?

Which chromosome from each of the 23 homologous pairs of both parents is inherited is a matter of chance. 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.

## How many different combinations of maternal and paternal chromosomes can be packaged in gametes in an organism whose diploid number is 16?

Using that formula, how many chromosomal combinations can result from meiosis when the diploid number is 16? = **256 different combinations**.

## How many different combinations of maternal and paternal chromosomes can be packaged in gametes made by an organism with a diploid number of 4 2n 4 )?

How do the four pairs of homologous chromosomes align and separate during meiosis? They align and assort independently to form any of **16 different combinations**.

## How many assortments of maternal and paternal chromosomes are?

The total possible number of different gametes is 2n, where n equals the number of chromosomes in a set. In this example, there are four possible genetic combinations for the gametes. With n = 23 in human cells, there are **over 8 million possible combinations** of paternal and maternal chromosomes.

## How many gender chromosome combinations are there?

These include **22 pairs** of “autosomes” (which refers to all chromosomes that are not sex chromosomes) and a pair of sex chromosomes, either an X and a Y (which makes for a male) or two Xs (female). That means the genetic signature for a person with 46 chromosomes is either 46,XY (males), or 46,XX (females).

## How many different chromosome combinations are possible for a gamete?

Humans have 23 pairs of chromosomes. That means that one person could produce **2 ^{23} different gametes**. In addition, when you calculate the possible combinations that emerge from the pairing of an egg and a sperm, the result is (2

^{23})

^{2}possible combinations.

## How many different combinations of chromosomes are possible in the gametes of the house fly?

The number of different combinations of chromosomes that are possible in the gametes is **2n**, where n is equal to the number of homologous pairs of chromosomes. For the fruit fly with four pairs of chromosomes, the number of possible combinations is 24 = 16.

## How many possible combinations of chromosomes could this organism produce as a result of independent assortment?

That’s why chromosomes are considered to be independently assorted so the zygote will eventually have a combination of different maternal and paternal chromosomes. Since the number of chromosomes in each gamete is 23 and the number of gametes is 2; thus, the number of possible combinations is 2^{23}, or **8,388,608**.

## How many different types of gametes could you produce from 3 chromosome pairs?

Hints For Biology 101 Exam #4

No. of homologous chromosome pairs (heterozygous genes) | No. of different gametes from each parent |
---|---|

3 (AaBbCc X AaBbCc) | 8 (2^{3}) |

4 (AaBbCcDd X AaBbCcDd) | 16 (2^{4}) |

20 pairs of chromosomes | 1,048,576 (2^{20}) |

23 pairs of chromosomes | 8,388,608 (2^{23}) |

## How many different combinations are possible in the gametes of an organism whose haploid number is 3?

With three pairs of chromosomes, there are 2^{3} = **8 combinations**.
