How many chromosomes does each human somatic cell contain?

46

1

What makes the Y chromosome different from other chromosomes?

Tiny with fewer genes
Only found in males
Sperm, but not eggs
Not fully homilies with X chromosomes

2

X and y are what chromosomes?

Sex chromosomes

3

All non-sex chromosomes are what?

Autosomes

4

2 chromosome sets
Somatic cells
Makes up everything

Diploid

5

Gametes
1 single set of chromosomes
Sex cells

Haploid

6

Do all animals have the same number of chromosomes?

No

7

Gametes are diploid or haploid

Haploid

8

Gametes are formed by the process of?

Meiosis

9

Draw a diagram of the human life cycle

See ch. notes

10

In animals, only gametes are haploid and everything else is diploid. Is this true for Protists, fungi and plants?

No

11

Meiosis is preceded by what?

Duplication

12

How many cell divisions does meiosis have?

2

13

How daughter cells does meiosis result in?

4

14

Portions of homologous chromosomes (not sister chromatids) are swapped during prophase 1

Crossing over

15

No synapsis
2 daughter cells
Identical to parent cell

Mitosis

16

Occurs during prophase
4 daughter cells
Genetically different from parent cell

Meiosis

17
