Biology - Reproduction

Question 1

Is there a fusion of gametes in A sexual reproduction

Answer 1

There is no fusion of gametes in A sexual reproduction and only contains 1 parent. There is no mixing of genetic info leading to genetically identical offspring.

Question 2

What is mitosis involved in?

Answer 2

Mitosis is only involved in asexual reproduction

Question 3

What does sexual reproduction involve?

Answer 3

Involves fusion of male and female gametes known as meiosis leading to the formation of non identical cells

Question 4

Is there a mixing of genetic info in sexual reproduction?

Answer 4

Yes and it leads to the variation of offspring

Question 5

Heterozygote

Answer 5

Individual with different alleles for a characteristic

Question 6

Homozygote

Answer 6

Individual two identical alleles for a characteristic

Question 7

Dominant allele

Answer 7

The phenotype will be apparent in the offspring even if only one of the allele is inherited

Question 8

Recessive

Answer 8

A phenotype that will only show up in the offspring if both of the alleles coding for that characteristic are inherited

Question 9

Alleles

Answer 9

Different forms of the same gene sometimes referred to as variants

Question 10

Genotype

Answer 10

The genetic makeup of an individual for a particular characteristic, for example hair or eye colour.
