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.
Answer:
Interphase
Explanation:
When a cell inst actively dividing, it is in a stage called interphase which is where a cell spends the majority of its time. During interphase, cells need to replicate their DNA so they have DNA to divide during mitosis.
A. increased demand for natural resources; need to create environmental laws to protect natural resources for human consumption; need to develop air quality control systems for big business; need to ensure proper disposal of human waste
Three different types of inks are used in this experiment. The ink are black, red and green in colour. During the course of the experiment, the black ink changes colour from light blue to dark blue and then to red. The red ink changes color from red to pink. The green ink changes colour from dark blue to green and then to yellow.
