Meiosis vocab

Question 1

Crossing-over

Answer 1

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

-in prophase 1

Question 2

Independent assortment

Answer 2

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

• where each homologous ends up is totally random
• increase in genetic variation

Question 3

Diploid

Answer 3

HAVING a full set of chromosomes

2n- 2 sets of chromosomes

n- the number of chromosome

2- # of chromosomes x that made

Question 4

Gametes

Answer 4

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

Question 5

Haploid

Answer 5

1/2 the set of DNA

• 1n

Question 6

Meiosis

Answer 6

The process of producing gametes.

- 2 phases of Meiosis: Meiosis 1 and Meiosis 2

Question 7

Sexual reproduction

Answer 7

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

Question 8

Asexual reproduction

Answer 8

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

Question 9

Mitosis

Answer 9

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

Question 10

Mating

Answer 10

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.)

Question 11

Fertilization

Answer 11

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

Question 12

Conditions for cell divisions

Answer 12

• nutrients
• temperature
• moisture
