Vocabular Words section 1 Chapter 10

Question 0

Genes

Answer 0

Functional units that controls inherited trait. Passed on from generation to generation

Question 1

Meiosis

Answer 1

• Cutting in half the number of Chromosomes
• Production of gametes (sex cells)
• Cell division
• two Haploids (n )form a diploid (2n)

Reduction division process, only occur in reproductive cells. Cells are not genetically identical. One diploid cell produces four haploid cells

Question 2

Fertilization

Answer 2

The process of gametes, which are haploids, combine to make a diploid. One haploid coming from a male and one coming from a female

Question 3

Homologous Chromosomes

Answer 3

One of two paired chromosomes from each parent. Carries genes for a specific trait at the same location.

Question 4

Haploids

Answer 4

Cell with half the number of chromosomes (n) as a diploid (2n) cell

Question 5

Diploid

Answer 5

Having two copies of each chromosome (2n)

Question 6

Crossing Over

Answer 6

Exchange of chromosomal segments between a pair of homologous chromosomes during prophase 1 of meiosis.

Question 7

Gametes

Answer 7

A haploid sex cell, formed during meiosis. Produces a diploid fertilized egg. Combines with a haploid sex cell.
