In meiosis I, segregation of chromosomes...that is, separating off into pairs, allows for crossing over to occur. Crossing over is one mechanism responsible for gene recombination to occur, and genetic recombination is one way that variations in traits increase.
A mutation in the gene makeup of the organism.
Cancer- certain mutations (changes) in a cell's genetic material may cause that cell to reproduce with out control.
UV rays and other radiation can indeed cause mutation.
Lots of things, the most common of which is cancer.
by being cheesy Edited answer: During prophase I of meiosis pairing among homologous chrosomes takes place. This is followed by crossing over. The recessive and dominant genes get interchanged during chiasma formation and such interchanged genetic material get separated in to different cells during mtaphase I. Hence, prophase I and metaphase I cause genetic variations in the male and female gametes. On randum mating among these gametes, genetic variation in the offsring are caused.
A genetic mutation can cause a variation, which may be harmless, or may be harmful, depending on where on the DNA molecule it occurs.
Sexual Reproduction Genetic mutation
mutations cause genetic variation, and vice-versa. If there is a genetic variation (or lack of one), then this can effect the severity of the mutation.

Genetic variation refers to the differences in DNA sequences among individuals within a population. This variation can arise through mechanisms such as mutation, recombination, and gene flow, and it is essential for evolution as it provides the raw material for natural selection to act upon.
Radiation can cause sunburn, cancer, genetic mutation.
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
Yes, the independent assortment of genes during meiosis does cause genetic variation.
A mutation in the gene makeup of the organism.
Two daughter cells with different DNA may represent a mutation or an error during cell division. This can lead to genetic variation and potentially cause abnormalities or changes in the characteristics of the cells.
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Two processes that can lead to inherited variation in populations are sexual reproduction, which involves the mixing of genetic material from two parents, and mutations, which are random changes in an organism's DNA that can be passed on to offspring.
