What is the result of a mutation during meiosis?
The offspring of the organism will have the mutation. -Apex
What is an important factor in increasing variety among sexually reproducing organisms?
Genetic recombination during meiosis is a crucial factor in increasing genetic variation among sexually reproducing organisms. This process involves the shuffling and exchange of genetic material between homologous chromosomes, leading to offspring with unique combinations of traits.
Why cross pollination produces more genetic variation in the offspring than self pollination produces?
Cross-pollination produces more genetic variation in offspring because it is a different set of DNA that is breeding with the parents DNA to produce the offspring (known as sexual reproduction). In asexual reproduction, the parent plant uses a clone DNA to self pollinate thus creating an exact copy of the parent. Asexual reproduction inhibits genetic variation because the offspring will never develop mutations that could help natural selection.
What is it called when genes swap during meiosis?
Genes swapping during meiosis is called genetic recombination or crossing over. This process allows for new combinations of genetic material to be produced, increasing genetic variation among offspring.
What is the advantage of meiosis over binary fission?
the benefit of meiosis is that there is genetic recombination hence, helps in variation of characters .that is the reason why children are SIMILAR to their parents but DO NOT look like them completely.
When do sister chromatids cross over?
Sister chromatids do not cross over. Cross over occurs between homologous chromosomes during meiosis I, where genetic material is exchanged between non-sister chromatids, leading to genetic variation in the offspring.

Crossing over causes the offsprings to be different from the parent?
Crossing over is a genetic process that occurs during meiosis, where sections of DNA are exchanged between homologous chromosomes. This can lead to genetic variation in offspring as it results in new combinations of alleles being passed on from the parents.
Which cross would produce the least phenotypic variation?
There are two choices that produce the least phenotypic variation. AA times aa produces only Aa offspring. AA times Aa produces and AA and Aa offspring.
Why do homologous chromosomes cross over?
Homologous chromosomes cross over during meiosis to exchange genetic material. This process promotes genetic diversity by shuffling genes between the homologous chromosomes, leading to variation in offspring.
In what two ways does meiosis provide genetic variation?
The two sources of genetic variation in a cell during Meiosis are crossing-over during synapse and independent assortment.

What is produced the end of meiosis?
Gametes, haploid cells. They have half of the genetic material in the original cell. They're genetically different due to cross over and independent assortment - to create variation.
How does meiosis contribute to genetic variation?
Meiosis produces gametes with different combinations of genes through crossing over and random assortment of chromosomes during meiosis I and II. This leads to genetic variation as each gamete contains a unique set of genetic information that is different from the parent cells.
