Study Notes

Alleles are different versions of the same gene, where each individual has two alleles for each gene, which can be homozygous (two of the same alleles) or heterozygous (two different alleles).
Dominant alleles are always expressed over recessive alleles, determining the phenotype of an organism.
Genotype refers to the collection of alleles an individual has, while phenotype refers to the observable characteristics resulting from the genotype.
Different genes interact to determine various characteristics in individuals, with traits sometimes being influenced by multiple genes.
Understanding alleles, dominant and recessive traits, genotype, and phenotype are crucial in comprehending genetic inheritance patterns.
