Reproduction (Rev3)

Question 1

Asexual reproduction

Answer 1

No fusion of gametes
One parent
There is no mixing of genetic information, leading to genetically identical offspring (clone)

Question 2

What is mitosis only involved in

Answer 2

Asexual reproduction

Question 3

Sexual reproduction

Answer 3

The joining (fusion) of male and female gametes formed by meiosis. 
Mixing of genetic information that leads to variation in the offspring

Question 4

Where does meiosis lead to

Answer 4

To the information of non-identical cells, sperm and egg cells in animals, and pollen and egg cells in flowering plants

Question 5

Mitosis

Answer 5

Making identical two

Question 6

Meiosis

Answer 6

Making eggs (and sperm)

Question 7

Genes

Answer 7

Sections of a chromosome that carry specific information

Question 8

Different versions of genes

Answer 8

Alleles

Question 9

How many alleles are in a gene

Answer 9

2 - 1 from mum and 1 from dad

Question 10

What does the combination of alleles determine

Answer 10

Determines the characteristics of that individual

Question 11

Genotype

Answer 11

The gene combination which is either heterozygous or homozygous. (Eg BB, bb)

Question 12

Phenotype

Answer 12

The result of the gene combination. (Eg blue eyes, brown eyes)

Question 13

Heterozygous

Answer 13

If the gene combination is dominant and recessive combination. (Eg Bb, bB)

Question 14

Homozygous

Answer 14

If the gene combination is either both dominant or both recessive. (Eg BB, bb)

Question 15

Dominant

Answer 15

An allele that will be chosen over another allele. (Dominant over recessive). Shown by capital letter.

When the gene combination contains 2 dominant alleles (eg BB, CC) or 1 dominant allele (Bb, bB) it is a dominant gene.

Question 16

Recessive

Answer 16

When the allele will not be chosen over another allele. Shown by lower case letter.
