Crossing Over

Front

What is the result of crossing over?

Back

recombination

Front

CROSSING OVER INCREASES

Back

GENETIC VARIATION

Front

The process of crossing over occurs in what phase of meiosis? Options: anaphase 1, prophase 1, prophase 2, telophase 1

Back

prophase 1

Front

When does crossing over occur?

Back

Prophase I

Front

When are homologous chromosomes separated? Options: Anaphase I, Anaphase II, Telophase I, Telophase II

Back

Anaphase I

Front

What does meiosis create?

Back

Gametes

Front

Meiosis is needed in order to:
- Create diploid gametes
- Create haploid gametes
- Create identical new cells
- Synthesise proteins

Back

Create haploid gametes

Front

Gametes are considered to have half the number of chromosomes so are therefore referred to as:

Back

HAPLOID (N)

Front

The diagram shows a diploid cell (2n=4) with genotypes.

Name the genotypes of possible daughter cells that have undergone crossing over during meiosis.
