When does Variation produced by sexual reproduction starts?
during meiosis
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis?
Crossing over, or genetic recombination, is the process in meiosis where sections of chromosomes are exchanged between homologous chromosomes, leading to genetic variation in offspring. This event occurs during prophase I of meiosis.
Does crossing over occur in meiosis?
Yes, crossing over occurs during meiosis. It is the process where homologous chromosomes exchange genetic material, increasing genetic variation among offspring. This occurs during prophase I of meiosis.
What is the important event during meiosis that results in genetic variation?
Crossing-Over
During which process does crossing-over occur?
Crossing-over occurs during meiosis, specifically during prophase I. It involves the exchange of genetic material between homologous chromosomes, resulting in genetic variation in offspring.

What two factors introduce genetic variation during the process of meiosis?
Crossing over (genetic material exchange between homologous chromosomes) during prophase I and independent assortment of chromosomes during metaphase I contribute to genetic variation during meiosis.
Differences between mitosis and meiosis?
Mitosis is a cell division process that produces two daughter cells with the same number of chromosomes as the parent cell, while meiosis is a cell division process that produces four daughter cells with half the number of chromosomes as the parent cell. Mitosis is involved in growth, repair, and asexual reproduction, while meiosis is involved in the formation of gametes for sexual reproduction.
Does meiosis have variation?
During meiosis, genetic recombination of homologous chromosomes occurs. So meiosis does result in genetic variation. After prophase I, during which crossing over occurs, every chromosome will have some maternal DNA and some paternal DNA.

Is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis?
This process is known as genetic recombination or crossing over. During meiosis, homologous chromosomes exchange sections of DNA, resulting in the shuffling of genetic material between maternal and paternal chromosomes. This contributes to genetic diversity by creating new combinations of alleles in offspring.
