• Heredity is the passing of traits from parents to offspring.
• Genetics is a branch of biology that deals with heredity and variations of organism
• Variation is the differences in the characteristics of individuals in a species
• Trait is distinguished by the feature of a character in the genes
• Gene is a functional unite of heredity
• DNA carries the genetic information in the body's cell
• The father of genetics is Gregor Mendel. He discovered the laws of inheritance.
• Chromosomes is the threadlike structure that carries heredity information from one generation to the next
• Alleles are one or two alternative forms of a gene that are found at the same place on chromosomes
• Phenotype is a physical appearance of the genes
• Genotype is where all the genes are present in a cell of organism
• Dominant trait is when expressed by an organism when inherited
• Recessive trait is an allele that is masked or also covered by a dominant allele
• Homozygous is having two identical alleles of a particular gene, e.g. BB
• Heterozygous: having two different alleles of a particular gene or genes
