What is the allele frequency?
Keith_Richards [23]

Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population.

Usually it is expressed as a proportion or a percentage.

In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool.

The frequencies of all the alleles of a given gene often are graphed together as an allele frequency distribution histogram.

Population genetics studies the different "forces" that might lead to changes in the distribution and frequencies of alleles - in other words, to evolution.

Besides selection, these forces include genetic drift, mutation and migration.

Which is part of the spindle apparatus?
professor190 [17]

Chromatin is a part of the spindle apparatus

Explanation:

Chromosome is not only responsible for genetic material.  Chromatin is that substance which consists of protein and DNA.  Here DNA carries genetic instruction. Histones are main proteins of chromatin. It is also called the packaging of element for the DNA.

In two forms chromatin exist. One is euchromatin and another is heterochromatin. Euchromatin is less condensed and it can be transcribed. Heterochromatin is highly condensed and typically not transcribed. Chromosomal pathway regulates spindle assembly.
