Know what the Chi square and its uses

Pedigree

incomplete dominance when neither allele can express itself completely (blending pink flower)

wild type + prevalent type observed in nature

mutant usually recesive, and is the least observed phenotype in a species

gene complementation (cinnabar 1 / 2 x scarlet)

lethal mutation, sterile mutation

central dogma

polydactyly is dominant

penetrance is the rate at which the gene is expressed, even if it's dominant.

(variable) expressivity the degree to which the trait is developed (formed)

Epistasis The presence of an allele can influence whether other genes are expressed or not

pleiotropy one gene can have several effects

hybrid vigor stronger than the parent

hybrid depression sometimes can also be weaker, or even unable to reproduce

(heterosis)

Chapter 5 – bold words

hemizygous – only one copy of the gene (males only)

autosomes

homologue

barr body random inactivation of an X chromosome in females, which can reactivate [how?]
