genetics

• Incomplete dominance is when neither allele is fully expressed and creates blending.
• Codominance is when both alleles are expressed in the phenotype.
• Polygenic inheritance is phenotype traits that are based on multiple genes.
• Sex-linked genes are only found on the X or Y chromosome.
• Linked genes are close together on the chromosome and are more likely to be inherited together.
• Pleiotropy is when one gene has multiple effects on the phenotype.
• Epistasis is when one gene masks another gene from being expressed.
• Carriers are individuals that are heterozygous for a recessive disease.
• Pedigrees are a way to trace traits as they're passed down through families.
• In pedigrees, males are usually squares and females are circles.
