Meiosis

Question 1

What is a Diploid?

Answer 1

Diploid (2n) is the number of chromosomes, and in humans the Diploid number is 46.

Question 2

What is a Haploid?

Answer 2

Haploid (n) is the number of pairs of chromosomes and in humans the Haploid number is 23.

Question 3

What are Autosomes?

Answer 3

There are 22 different pairs of chromosomes and a pair of sex chromosomes/gonosomes.

Question 4

What Sex Chromosomes do Females have?

Answer 4

X X

Question 5

What Sex Chromosomes do Males have?

Answer 5

X Y

Question 6

What is a Homologous Pair?

Answer 6

A pair of identical chromosomes, one from your Mother and another from your Father.

Question 7

What is Gametogensis?

Answer 7

This is a process during which Gametes are formed.

Question 8

When does Meiosis take place?

Answer 8

During Gametogenisis.

Question 9

What are the Phases of Meiosis?

Answer 9

• Interphase (occurs before Meiosis)
• Prophase
• Metaphase
• Anaphase
• Telophase

Question 10

What is The Importance of Meiosis?

Answer 10

° Production of Haploid Gametes

° The halving effect of Meiosis overcomes the doubling effect of fertilization, thus maintaining a constant chromosome number from generation to the next.

° Introduces genetic variation

Question 11

How does Meiosis introduce Genetic variation?

Answer 11

° Crossing over ( Prophase 1 )
° Random Agrangement ( Metaphase 1 and 2 )
