Sexual reproduction

Question 1

genetic material of two different parents combine to form offspring

Answer 1

sexual reproduction

Question 2

haploid female sex cell, gets fertilized by sperm

Answer 2

egg

Question 3

haploid male sex cell, fertilizes an egg cell

Answer 3

sperm

Question 4

where do egg cells get created

Answer 4

ovary

Question 5

where do sperm cells get created

Answer 5

testis

Question 6

when a sperm and an egg join together and combine DNA

Answer 6

fertilization

Question 7

diploid new cell formed by fertilization (future baby!)

Answer 7

zygote

Question 8

cells that have two sets of chromosomes

Answer 8

diploid

Question 9

cells that have just one set of chromosomes

Answer 9

haploid

Question 10

pair of chromosomes that have genes for the same traits

Answer 10

homologous chromosomes

Question 11

process that creates 4 haploid sex cells; process that makes sperm and eggs

Answer 11

meiosis

Question 12

two reasons why meiosis is important

Answer 12

• creates haploid sex cells so that offspring are diploid
• allows for genetic variations in offspring (so kids aren’t identical to their parents or siblings)

Question 13

3 differences between mitosis and meiosis

Answer 13

• meiosis only produces sperm and eggs; mitosis produces all other body cells
• meiosis produces haploid cells; mitosis produces diploid cells
• meiosis produces 4 cells; mitosis produces 2 cells

Question 14

2 advantages of sexual reproduction

Answer 14

• genetic differences that help some organisms to survive better than others
• selective breeding can create plants and animals with good traits

Question 15

2 disadvantages of sexual reproduction

Answer 15

• takes time and energy to make sex cells and find mates
• finding mates exposes organisms to danger
