What is sexual reproduction?
Sexual Reproduction
Definition:
Sexual reproduction is a process by which two individuals of opposite sexes come together to produce offspring with genetic variations different from their parents.
Key Points:
- Two parents are involved in sexual reproduction, each contributing genetic material to the offspring.
- Genetic recombination occurs during sexual reproduction, leading to genetic diversity in the offspring.
- Sexual reproduction involves the fusion of male and female gametes to form a zygote, which eventually develops into a new individual.
- Sexual reproduction promotes genetic variability, which is beneficial for the adaptation and survival of species in changing environments.
Process of Sexual Reproduction:
- Fertilization: The male gamete (sperm) fertilizes the female gamete (egg) to form a zygote.
- Genetic Variation: Genetic material from both parents combines to create a unique genetic makeup for the offspring.
- Meiosis: Specialized cell division process that produces gametes with half the number of chromosomes, ensuring genetic diversity.
- Recombination: Exchange of genetic material between homologous chromosomes during meiosis leads to new combinations of genes in offspring.
Advantages of Sexual Reproduction:
- Increased genetic diversity enhances the ability of species to adapt to changing environments.
- Allows for the repair of damaged DNA through genetic recombination.
- Eliminates harmful mutations by combining genetic material from two individuals.
