Meiosis is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes found in the parent cells.
What is sexual reproduction?
Sexual reproduction is the process by which two organisms contribute genetic material to produce offspring with unique combinations of genes.
What are the stages of meiosis?
The stages of meiosis are: prophase I, metaphase I, anaphase I, telophase I, cytokinesis I, prophase II, metaphase II, anaphase II, telophase II, and cytokinesis II.
What is the purpose of meiosis?
The purpose of meiosis is to produce gametes with half the number of chromosomes to ensure the offspring have the correct number of chromosomes.
What are the differences between meiosis and mitosis?
Meiosis produces gametes with half the number of chromosomes, while mitosis produces somatic cells with the same number of chromosomes as the parent cell.
What is crossing over?
Crossing over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis.
What is independent assortment?
Independent assortment is the random alignment and separation of homologous chromosomes during metaphase I of meiosis, leading to genetic variation.
What is fertilization?
Fertilization is the fusion of sperm and egg cells, resulting in the formation of a zygote.
What is the importance of genetic variation in sexual reproduction?
Genetic variation in sexual reproduction leads to increased adaptability and evolutionary success of a species.
What are the advantages of sexual reproduction over asexual reproduction?
Advantages of sexual reproduction include increased genetic variation, adaptability, and the ability to eliminate harmful mutations.
What is the importance of meiosis in humans?
Meiosis is important in humans as it produces gametes (sperm and egg cells) for sexual reproduction.
What are gametes?
Gametes are specialized cells (sperm and egg cells) that fuse during fertilization to form a zygote.
What is the haploid number of chromosomes in humans?
The haploid number of chromosomes in humans is 23.
What is the diploid number of chromosomes in humans?
The diploid number of chromosomes in humans is 46.
What are the end products of meiosis?
The end products of meiosis are four haploid daughter cells (gametes) with half the number of chromosomes as the parent cell.
