Diving to multiply

Question 1

Mitosis

Answer 1

a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Question 2

Meiosis

Answer 2

Process of going from diploid to haploid.
A parent cell (diploid) will undergo meiosis to create haploid daughter cells which halve the number of chromosomes.

Question 3

Recall the sex chromosomes for humans, and describe how these determine gender

Answer 3

In humans, sex chromosomes determine an individual’s biological sex. There are two types of sex chromosomes: X and Y. Each person typically has two sex chromosomes, which can be in one of two combinations:

Sex Chromosomes
XX - Female
XY - Male

Question 4

Diploid

Answer 4

A cell containing two copies of each chromosome

Question 5

Haploid

Answer 5

A cell that contains a single set of chromosomes.

Question 6

Genetic Variation

Answer 6

Genetic variation is the difference in DNA sequences between individuals within a population.

Question 7

Crossing over

Answer 7

The exchange of DNA between paired homologous chromosomes (one from each parent) that occurs during the development of egg and sperm cells (meiosis).
