1

Crossing-over

Process in Meiosis 1 in which segments of non-sister chromatids exchange segments of DNA

-in prophase 1

2

Independent assortment

During Meiosis 1 the homologous pairs will separate into daughter cells.

- where each homologous ends up is totally random

- increase in genetic variation

3

Diploid

HAVING a full set of chromosomes

2n- 2 sets of chromosomes

n- the number of chromosome

2- # of chromosomes x that made

4

Gametes

Specialized cells for reproduction (sex cells); all other cells are body cells (somatic cells)

5

Haploid

1/2 the set of DNA

- 1n

6

Meiosis

The process of producing gametes.
- 2 phases of Meiosis: Meiosis 1 and Meiosis 2

7

Sexual reproduction

Reproduction that involves the mixing of 2sets of DNA from 2 parents

-offspring are different from that of parents

-produces genetic diversity

-process of bringing nonidentical gametes together

8

Asexual reproduction

Producing offspring from a single parent; the offspring has the same DNA as that of the parent-clone/looks identical

9

Mitosis

Process of dividing a nucleons into 2 so that both have the correct amount of DNA

10

Mating

Members of the opposite gender come together at certain times of the year to reproduce/mate; during the most favourable time of the year to ensure the best possibility for survival of the offspring. (Food temperature, weather, etc.)

11

Fertilization

Gametes come together to form a zygote which becomes an embryos

-only 1 sperm to combine with each egg/ovum: ensures the correct amount of chromosomes

12

Conditions for cell divisions

-nutrients

-temperature

-moisture

Zygote

New diploid cell drones by the process of fertilization
