Genes
Specific part of a chromosome responsible for outward appearance. It's a small section of DNA
1 of 14
Locus
Position of a gene in a chromosome
2 of 14
Allele
A segment of the chromosome- alternative form of a gene
3 of 14
Dominant
Eg. If someone is heterozygous with a dominant allele for genes that gene will show in the phenotype. The allele is expressed if only one allele needed
4 of 14
Recessive
2 recessive alleles needed for phenotype to show
5 of 14
Co-dominant
Eg. White and red produce pink. Both alleles show as it is an intermediate form
6 of 14
Phenotype
The outward expression of a genotype
7 of 14
Genotype
The combination of alleles resulting in a phenotype
8 of 14
Homozygous
2 of the same allele eg. bb
9 of 14
Heterozygous 2 different allelels
Eg. Bb
10 of 14
F1
First generation
11 of 14
F2
2nd generation
12 of 14
Autozomes
22/23 chromosomes which are not related to sex determination
13 of 14
Sex chromosomes
X and Y. ** In females and XY in males
