Cell Division - Meiosis/Crossing Over

Question 1

meiosis

Answer 1

• Referred to as reduction division.
• This division results in 4 haploid cells.
• These cells are used in sexual reproduction and are called gametes.​​ ​​
• Cuts the number of chromosomes in half by separating homologous chromosomes in a diploid cell.
• Homologous chromosomes are chromosomes that code for the same things but one is from mom and one is from dad.
• A pair of homologous chromosomes make a tetrad.
  Contains 4 chromatids​

Question 2

crossing-over

Answer 2

• While homologous chromosomes are paired up they exchange portions of their DNA.
• This creates genetic variation within a population. ​
