mutation

mutation refers to a permanent change in the DNA sequence of an organism's genes

adaptation

Adaptation is a biological process whereby organisms change over time in response to their environment.

gene pool

gene pool refers to the total collection of genes and their different alleles present in a population of organisms

species

species is a fundamental unit of classification and represents a group of organisms that are capable of interbreeding and producing fertile offspring.

population

A population refers to a group of individuals of the same species that inhabit a particular geographic area and interact with one another

evolution

Evolution is the process of change in living organisms over time.

list 4 sources for genetic variation

Mutation: Genetic variation can arise through spontaneous mutations, which are changes in the DNA sequence of an organism's genes.

Genetic Recombination: During sexual reproduction, genetic recombination occurs when genetic material from two parent organisms is combined to create offspring.

Gene Flow: Gene flow refers to the movement of genes between different populations

Genetic Drift: Genetic drift is the random fluctuation of allele frequencies in a population.

What is an autosome?

A body chromosome or non-sex chromosome.

why do chromosomes double during interphase before mitosis?

so each daughter cell acquires the same number of chromosomes as the parent cell.

Name the cells organelles responsible for moving chromosomes to the centre of the cell during metaphase?

Centrioles by using spindle fibres.
