meiosis

Question 1

What happens during meiosis I?

Answer 1

During meiosis I, homologous chromosomes are separated into different daughter cells, reducing the chromosome number by half.

Question 2

What happens during meiosis II?

Answer 2

During meiosis II, sister chromatids are separated, creating genetic diversity in the resulting haploid cells.

Question 3

: How many daughter cells are produced in meiosis,

Answer 3

4 haploid daughter cells

Question 4

What is crossing over, and when does it occur?

Answer 4

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I of meiosis. It increases genetic diversity.

Question 5

What is independent assortment?

Answer 5

: Independent assortment refers to the random distribution of homologous chromosomes during Anaphase I, leading to genetic variation in gametes

Question 6

What is the significance of meiosis in sexual reproduction?

Answer 6

Meiosis creates genetic diversity among offspring, enhancing the adaptability and evolution of species over generations.

Question 7

Front: Why is the haploid number crucial for genetic diversity?

Answer 7

The haploid number (n) is crucial for genetic diversity because it ensures that during sexual reproduction, gametes (sperm and egg cells) fuse, combining unique sets of genetic information. This fusion creates offspring with diverse genetic combinations, fostering adaptation and evolution within populations. The haploid number also allows for genetic recombination during meiosis, promoting further diversity by shuffling genetic material between homologous chromosomes.
