the number of chromosomes in a human cell - always an even number
Haploid number
1 of 16
Chromosomes grouped in pairs. In each pair one chromosome has been inherited from the mother and one from the father
Homolegous chromosomes
2 of 16
The type of cell division that makes plants and animals grow
Mitosis
3 of 16
Sperm or egg cells
Gametes
4 of 16
Cells with half the number of chromosomes
Diploid cells
5 of 16
What the cell splits to be
Daughter cells
6 of 16
A version of a particular gene
Allele
7 of 16
If both alleles are the same in a homologous pair
Homozygous
8 of 16
If both alleles in a homologous pair are different
Heterozygous
9 of 16
The genes that are passed on to you
Phenotype
10 of 16
Expressed in a vell's phenotype. Only 1 copy needs to be inherited for it to be expressed. Represented by a CAPITAL LETTER
Dominant allele
11 of 16
Only expressed if 2 copies are present
Recessive allele
12 of 16
The exact description of the combination of genes you have
Genotype
13 of 16
The 2 stage process of cell division which reduces the chromosome number of the daughter cells. It is involved in making the gametes for sexual reproduction
Meiosis
14 of 16
A genetic condition inherited through a dominant allele resulting in extra fingers and toes
Polydactyly
15 of 16
A genetic disease that affects the lungs, digestive & reproductive systems. Inherited through a recessive allele
Cystic fibrosis
16 of 16
