B12-Reproduction and Cell division.

Question 1

What happens in asexual reproduction?

Answer 1

In asexual repdocution, there is no fusion of gametes and only one parent. There is no mixing of genetic information, leading to genetically identical offspring.

Question 2

What type of cell division is involved in asexual reproduction?

Answer 2

Only mitosis is involved in asexual reproduction.

Question 3

What happens in sexual reproduction?

Answer 3

Sexual reproduction involves the joining(fusion) of male and female gametes formed by meiosis. Meiosis lead to the formation of non-identical cells, sperm and egg cells in animals, and pollen and egg cells in flowering plants.

Question 4

genes

Answer 4

Sections of a chromosome carry specific information; these are called genes

Question 5

chromosomes

Answer 5

They carry genetic information

Question 6

alleles

Answer 6

Different forms of same genes sometimes referred to variations

Question 7

heterozygous

Answer 7

Individual with different alleles for a characteristics.

Question 8

homozygous

Answer 8

Individual with two identical alleles for a characteristic

Question 9

phenotype

Answer 9

The physical appearance/biochemistry of an individual for a particular characteristic

Question 10

genotype

Answer 10

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

Question 11

dominant allele

Answer 11

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

Question 12

Recessive

Answer 12

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