Sexual reproduction and genetic variation | Middle school biology | Khan Academy

Sexual reproduction creates diversity through combining genetic information from two parents, resulting in unique offspring with millions of possible chromosome combinations. This process involves diploid organisms producing haploid gametes that fuse during fertilization to create a genetically varied and distinct individual.
Insights
- Sexual reproduction combines genetic information from two parents to create diversity in offspring through millions of possible chromosome combinations.
- Fertilization fuses haploid gametes to form a diploid offspring, leading to genetic variation and uniqueness in individuals within biological families and populations.

"Sexual Reproduction: Creating Genetic Diversity in Offspring"
- Sexual reproduction is a mechanism that creates diversity in biological families and populations by combining genetic information from two parents through chromosomes.
- Organisms with two sets of chromosomes are called diploid, while gametes, which are haploid cells, contain half the genetic information of diploid cells.
- Fertilization occurs when haploid gametes fuse to form a diploid offspring with homologous chromosome pairs, leading to genetic variation and diversity.
- The inheritance of chromosomes from both parents during sexual reproduction results in millions of possible chromosome combinations in offspring, making each individual unique and genetically distinct.
