 As you cannot do controlled crosses you need to have a lot of data from different family groups and compile recombination frequencies for these across numbers of these using statistical methods. You can also use markers such as microsatellites <span> which are easily scored.</span>

A chimpanzee has 48 chromosomes. When performing meiosis, one chromosome does not split properly in Anaphase II, causing one cel
Schach [20]

Answer:

The mutated cell will have 25 chromosomes.

Explanation:

Meiosis is a cell division process in sexual reproduction which involves two successive divisions of a cell having a diploid (2n) number of chromosomes into four daughter cells having a haploid (1n) number of chromosomes.

Meiosis consists of two successive nuclear divisions, meiosis I and meiosis II. Each division consists of these stages: prophase, metaphase, anaphase, and telophase.

Anaphase consists of anaphase I and II. During anaphase II, the centromeres linking the two pairs of chromosomes which are called chromatids separate, and the sister chromatids move toward the opposite poles of the cell and are now called chromosomes.

Therefore in the chimpanzee having 48 chromosomes, after underoing meiosis, each daughter cell will have 24 chromosomes. If there is a case of non-separation of one chromosome, the cell will have 1n + 1 chromosomes i.e. 24 + 1 = 25 chromosomes.
