Bio B2 Inheritance

HideShow resource information
Diploid Number
46 chromosomes in a normal body cell
1 of 9
Haploid Number
23 chromosomes in the gametes
2 of 9
Gene
small section of DNA
3 of 9
DNA
chemical that makes up genes
4 of 9
Allele
different form of a gene
5 of 9
Mitosis
ASEXUAL (1) - each chromosome produces an identical copy of itself. (2) - copies separate and move to opposite parts of the cell. (3) - each daughter cell receives the same number of chromosomes.
6 of 9
Meiosis
(1) - homologous chromosomes pair up in the egg. (2) - each chromosome produces a copy of itself. (3) - cell divides into two. (4) - the two cells divide again to make two more cells.
7 of 9
Differences between MITOSIS and meiosis
Mitosis - genetically identical cells, diploid number of chromosomes, 1 cell division, produces 2 cells
8 of 9
Differences between mitosis and MEIOSIS
Meiosis - genetically different, haploid number of chromosomes, 2 cell divisions, produces 4 cells
