Topic 3C.1 Cell Differentiation

cell differentiation

the process by which a less specialised cell becomes more specialised for a particular function

locus

place on a chromosome where any particular gene is found

multiple alleles

more than two possible variants at a particular locus

codominant

both alleles are expressed in the phenotype

gene linkage

when genes for two different characteristics are found on the same chromosome and are close together so they are linked and inherited as a single unit

polygenic

phenotypic characters determined by several interacting genes

digenic (dihybrid) inheritance

the inheritance of two pairs of contrasting characteristics at the same time
