Passed Combination Alleles Gametes Random Fertilisation Areas Genetic

Genetic variation arises from mutations, genetic recombination during meiosis (independent assortment and crossing-over), and random fertilization of gametes.

Variația genetică provine din mutații, recombinarea genetică în meioză (asortarea independentă și crossing-over) și fertilizarea aleatorie a gameților.

Front Areas that genetic variation can arise from?
Back Mutations- changes to genes and chromosomes may or may not be passed onto next generation

Meiosis- new combination of alleles created and passed into gametes

Random fertilisation of gametes- This produces a new combination of alleles and the offspring are different from parents. Which gametes fuses with which gamete during fertilisation is a random process.
