Lesson 4 - Quarter 1

• Phenotype - it refers to an individual's observable traits, such as height, eye color and blood type.​
• Genotype - it refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes.​
• Incomplete Dominance - neither allele is completely dominant over the other, resulting in a phenotype that is a blend of the two alleles.​
• Codominance - both alleles are fully expressed in the heterozygous condition, resulting in offspring with both traits visible simultaneously.​
• Multiple Alleles - or a particular gene, but an individual can only carry two of these alleles (one from each parent). The combination of these alleles determines the phenotype.​
• Sex-linked Traits - as related to genetics, refer to characteristics (or traits) that are influenced by genes carried on the sex chromosomes. ​
• Dominance and Reccessiveness - the first generation shows only one trait while the other trait is hidden
• Segregation - only one trait is inherited
• Independent Assortment - inherited independently
