Activity 1 Genetics and Inheritance
Terminology .enes ƚ The blueprint to the human body! ƚ Instructions made up of DNA base pairs that code for proteins. Ƃ Adenine (A) and Thymine (T) Ƃ Cytosine(C) and GUanine (G) ƚ The length of these gene sequences vary in length, from a couple of hundred base pairs to millions. ƚ We have two copies of each gene in our genome. ƚ Humans have between 20,000 and 25,000 genes
% lleles ƚ Different versions of the same gene. Ƃ Examples: ż Gene = Eye color, Alleles = blue allele, brown allele +ominMant vs 9>eOcessive (alleles) ƚ A 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. Ƃ Dominant allele represented by a capital letter (i.e. A, B, etc.). Ƃ Recessive alleles are represented by a lowercase letter
.enotype ƚ A set of two alleles for a specific gene Ƃ AA, Aa, aa, BB, Bb, bb, etc ƚ Each parent passes down one allele copy to their offspring. /4 omozygous vs /4eterozygous ƚ For a specific gene, a homozygous individual contains either two dominant alleles or two recessive alleles in their genotype.
