Meiosis and Genetic Variation

Front

What is crossing over?

Back

The exchange of pieces of chromatin between homologous chromosomes during Prophase I of meiosis.

Front

How many chromosomes do the egg and sperm cells of a mosquito have if the mosquito has 6 chromosomes?

Back

3

Front

What type of daughter cells does meiosis produce?

Back

Genetically different daughter cells.

Front

What does the Law of Independent Assortment state?

Back

Alleles will be inherited without influencing each other.

Front

How does meiosis differ from mitosis?

Back

Meiosis reduces the number of chromosomes by half, whereas mitosis keeps the same number.

Front

What is the purpose of meiosis?

Back

To produce gametes (egg and sperm) for sexual reproduction.

Front

What is a gamete?

Back

A reproductive cell (sperm or egg) that contains half the genetic material of an organism.

Front

What is the significance of genetic variation in meiosis?

Back

It increases diversity in a population, which can enhance survival and adaptation.

Front

What is the role of homologous chromosomes in meiosis?

Back

They pair up during meiosis and can exchange genetic material through crossing over.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells have one set of chromosomes (n), while diploid cells have two sets (2n).
