Variation (4)

Factors that cause variation (genetic factor) (1)

Crossing over between homologous chromosome during meiosis enables the exchange of genetic materials and produces a new genetic combination

Factors that cause variation (genetic factor) (2)

Independent assortment of chromosomes produces gametes that have different genetic information

Factors that cause variation (genetic factor) (3)

Random fertilization between male and female gametes produces zygote with different genotype combination

Factors that cause variation (genetic factor) (4)

Chromosome and gene mutations produce a new phenotypes due to changes in genetic information
