Alleles, Genetics and Variation

Buzzwords – Technical Jargon in GeneticsAllele – two different versions of the same gene (one from mum and one from dad)

Chance – probability (as either a fraction or a percentage. E.g. 1 out of 4 or 25%)

Punnett Squares – the square chart for working out inheritance

Dominant – the stronger allele (version of the gene)

Recessive – the weaker allele (version of the gene)

Pure bred – both alleles for a gene are the same as each other

Homozygous – means pure bred

Heterozygous – the two alleles (for a gene) are different
