Bio G: Inheritance (PAPER 2)

Question 1

Homologous pair

Answer 1

One gene inherited from mother, one from the father

Question 2

Allele

Answer 2

Different version of a gene

Question 3

Genotype

Answer 3

an allele pair for each characteristic

Question 4

Phenotype

Question 5

Gamete

Answer 5

Question 6

Diploid

Answer 6

Two full sets of chromosomes, one from each parent

Question 7

Haploid

Answer 7

A single set of unpaired chromosomes

Question 8

Mitosis cell division process (PAPER 1)

Answer 8

DNA in chromosomes copy itself for mitosis.
DNA condenses to become more visible and membrane around the nucleus disappears.
Chromosome and its copies line up in middle of the cell.
Chromosome and its copies get pulled to each end of the cell.
Membranes form around the ends of the cell.
Cell Membrane and Cytoplasm divide
Two identical daughter cells formed.

Question 9

Comparison of mitosis and meiosis

Answer 9

meiosis produces gametes whereas mitosis is for growth and repair.
meiosis produces 4 unique haploid cells where mitosis produces 2 identical daughter cells.
Meiosis gives variation where mitosis are identical.
