B5.1.3 - Meiosis Flashcards
1
Q
What are diploid cells?
A
Cells which contain 2 sets of chromosomes
2
Q
What are haploid cells?
A
Cells which contain one set of chromosomes
3
Q
What is a zygote?
A
A fertilised egg
4
Q
What is the genome?
A
All the genetic material present in an organism
5
Q
What happens during fertilisation?
A
2 haploid gamete cells join together to form a diploid cell called a zygote. This then divides many times by the process of mitosis to produce a new organism
6
Q
What are gametes?
A
They are sex cells
7
Q
How are gametes made?
A
They are produced by meiosis which results in 4 haploid cells being produced from one diploid parent cell
8
