Study Notes
Locus and Alleles
- A locus is a specific location on a chromosome where a gene or a genetic marker is located
- If a locus is a single nucleotide, there are 4 possible alleles (A, C, G, and T)
Mendel's Genetic Experiments
- Mendel worked with pea plants ( Pisum sativum) in his genetic experiments
- He studied the inheritance of traits in pea plants to establish the laws of inheritance
Law of Independent Assortment
- The law of independent assortment worked for Mendel because he studied traits that were controlled by genes located on different chromosomes
- This allowed him to observe the independent segregation of alleles during gamete formation
Hardy-Weinberg Equilibrium
- The Hardy-Weinberg Equilibrium compares the genotype frequencies of a population at genetic equilibrium
- In the Hardy-Weinberg Equilibrium, the probability of two alleles being identical by descent is 0 (zero)
- The Hardy-Weinberg Equilibrium is a state in a population where the allele and genotype frequencies remain constant from one generation to the next
- The expected frequency of heterozygotes in the Hardy-Weinberg Equilibrium is 2pq, where p and q are the frequencies of the two alleles
