BIO 182 EXAM 1 STUDY GUIDE
alleles - Answers -variant forms of genes
an individual carries two genes for a given character
variant forms of genes are known as - Answers -alleles
Mendel's Law of Segregation - Answers -two alleles segregate during the process that
gives rise to gametes, so every gamete receives only one allele
genotype - Answers -genetic makeup of an organism
phenotype - Answers -description of the traits an organism displays
Inheritance pattern - Answers -Pair of alleles -located on an autosome-(w/ a
dominant/recessive relationship) determines pattern of traits
Simple Mendelian Inheritance pattern - Answers -pattern of traits = determined by pair
of alleles that have dominant/recessive relationship.
presence of a dominant allele masks the recessive allele
x linked inheritance - Answers -type of mendelian inheritance pattern
pattern of traits determined by genes on the x chromosome that display a
dominant/recessive relationship
x linked inheritance traits occur more frequently
incomplete dominance - Answers -type of mendelian inheritance pattern
when the heterozygote has a phenotype intermediate to the. phenotype of the
homozygotes
ex: cross btw red & white flowers produces pink offspring
codominance - Answers -mendelian inheritance pattern
occurs when the heterozygote expresses both alleles simultaneously
epistasis - Answers -mendelian inheritance pattern
type of gene interaction
