MOD 3 Sexual and Asexual Reproduction

Question 1

Reproduction

Answer 1

The production of offspring by a sexual or asexual process

Question 2

Asexual reproduction

Answer 2

A singular organism crates the offspring, which means it is a clone of the parent organism

E.g yeast

Question 3

Sexual Reproduction

Answer 3

When two organisms contribute to creating a hybrid of both parents

E.g penguins

Question 4

Chromosome

Answer 4

Rod-like structures where genes are located

Question 5

Alleles

Answer 5

Different versions of genes that code for the same trait

Question 6

Phenotype

Answer 6

The physical expression of that trait

Question 7

Genotype

Answer 7

Are the alleles that are carried on an organism’s chromosomes

Question 8

Evolution

Answer 8

The process by which populations change over time

Question 9

Meiosis

Answer 9

A type of cell division that results in four daughter cells with half as many chromosomes as the parent cell

Question 10

Gametes

Answer 10

Matured daughter cells

Question 11

Germ cell

Answer 11

A cell that will undergo meiosis to become gametes

Question 12

DNA

Answer 12

Genetic material which codes for the traits in offspring (CHECK)

Question 13

Sister chromatids

Answer 13

Two identical strands of DNA formed when DNA replicated during interphase

Question 14

Homologous chromosomes

Answer 14

Chromosomes of similar size with a matching set of genes

(one chromosome is from the mum and one from the dad)

Question 15

Diploid

Answer 15

The original parent cell which contains a complete set of homologous chromosome pairs

Question 16

Haploid

Answer 16

Each of the four daughter cells which contains half the original parent cell’s chromosomes

Question 17

Sperm Cells

Answer 17

Are spermatids which have developed into gametes (also called sperm cells)

Question 18

Ovum

Answer 18

A mature female reproductive cell which can divide and give rise to an embryo

(Usually only after fertilization by a male cell)

Question 19

Zygote

Answer 19

A fertilized female gamete

Question 20

Crossover

Answer 20

When paired up homologous chromosomes exchange sections

(The action of exchanging is a crossover)
