Activity 1 Genetics and Inheritance
Terminology.enesƚThe blueprint to the human body!ƚInstructions made up of DNA base pairs that code for proteins.ƂAdenine (A) and Thymine (T)ƂCytosine(C) and GUanine (G)ƚThe length of these gene sequences vary in length, from a couple of hundred base pairs to millions. ƚWe have two copies of each gene in our genome.ƚHumans have between 20,000 and 25,000 genes
%llelesƚDifferent versions of the same gene.ƂExamples: żGene = Eye color, Alleles = blue allele, brown allele+ominMant vs 9>eOcessive(alleles)ƚA dominant allele has a greater strength/presence over a recessive allele. This means that dominant alleles tend to be more common than recessive alleles are more likely to be expressed physically.ƂDominant allele represented by a capital letter (i.e. A, B, etc.).ƂRecessive alleles are represented by a lowercase letter
.enotypeƚA set of two alleles for a speciﬁc geneƂAA, Aa, aa, BB, Bb, bb, etcƚEach parent passes down one allele copy to their offspring./4omozygous vs /4eterozygousƚFor a speciﬁc gene, a homozygous individual contains either two dominant alleles or two recessive alleles in their genotype.
