## How many combinations of gametes are possible when chromosomes assort independently in meiosis?

In particular, Sutton pointed out that the independence of each chromosome during meiosis means that there are **2 ^{n} possible combinations** of chromosomes in gametes, with “n” being the number of chromosomes per gamete.

## How many different combinations of gametes can result from independent assortment of an organism has a haploid number of 8?

Because each pair of homologous chromosomes is positioned independently in metaphase I, the first meiotic division results in the independent assortment of paternal and maternal chromosomes into daughter cells. In a case in which 2n = 8, **16 combinations** of chromosomes are possible for gametes.

## How many different combinations of chromosomes can be packaged by in a gamete by an organism with a diploid number of 8 2n 8 )?

The diploid number of chromosomes in a certain animal is 8 (2n = 8). 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 combinations are possible when chromosomes assort independently into gametes ignoring crossing over )?

They align and assort independently to form any of **16 different combinations**.

## How many possible genetic combinations can arise from meiosis?

= **256 different combinations**.

## How do you calculate the number of possible combinations of a chromosome?

The possible combinations are equal to **2 ^{n}**, where n is the haploid number. For the organism in Figure 9-18, n = 2, so the number of chromosome combinations is 2

^{2}, or 4. For a human, n = 23, so there are 2

^{23}, or about 8 million, possible chromosome combinations!
