Define genotype
The genetic combination that each organism has
1 of 15
Gene
A section of DNA on a chromosome that usually codes for a particular polypeptide
2 of 15
Mutation
A change in the sequence of DNA bases which changes the genetic code
3 of 15
Allele
A different variation of a gene
4 of 15
Multiple Alleles
A gene that has two or more possible versions
5 of 15
Co-dominance
When a gene has two dominant alleles which are both expressed.
6 of 15
Dominant Allele
An allele that is always expressed in the phenotype of an organism. It only need one of the allele for it to b expressed
7 of 15
Recessive Allele
An allele only expressed when in a homozygous pair.
8 of 15
Monohybrid
investigations that examine the inheritance of a single characteristic:
9 of 15
Dihybrid
investigations that examine the inheritance of two characteristics
10 of 15
Linkage
when two or more genes are located on the same chromosome
11 of 15
Autosomal linkage
Linked genes which are on non-sex chromosomes
12 of 15
Sex linkage
linked genes are on sex chromosomes - therefore specific characteristic is more likely to be inherited in either male or female offspring
13 of 15
Epistasis
interaction of non-linked genes where one masks the expression of the other.
14 of 15
Chi-squared test
statistical test to find out whether the difference between observed vs expected data is due to chance or ‘goodness of fit’ of a hypothetical model.
