Question

Meiosis Questions:

1. How many chromatids are present in one homologous pair of chromosomes?
2. What is meant by “crossing-over” in meiosis, and how did your model depict this?
3. What effect does crossing-over during meiosis have on the genetic makeup of daughter cells?
4. Why must the number of chromosomes in reproductive cells (gametes) be different than the number of chromosomes in the rest of an organism’s cells (somatic cells)?

Answer 1

Step-by-step explanation:

1. Two sister Chromatids
2. Crossing over is the exchange of genetic material between two homologous chromosomes to give rise to recombinant chromosomes
3. allows the daughter cells of meiosis to be genetically unique from one another.
4. because the DNA of the parent cell is shuffled before the cell divides.
