Ch 12 Deck Flashcards
genetic material received from parents
inheritance
likelihood (chance) an event might occur
probability
of ways a specific outcome can happen divided by # of total outcomes
What is the equation for probability?
cell division that produces gametes (reproductive cells)
meiosis (my-O-sis)
cells that contain pairs of chromosomes(one from each parent)
diploid(DIP-loid)
cells that contain only ONE chromosome from a matching pair(this occurs only in reproductive cells)
haploid(HAP-loid)
genetic planthe combination of alleles(the “type-o-genes” an organism has)
genotype(GENE-o-type)
the traits, or characteristics of an organism(the expression of genetic info)
phenotype(FEEN-o-type)
inheriting two differing forms of a particular gene(Example: Tt)
heterozygous(het-er-oh-ZY-gus)
inheriting two identical forms of a particular gene(Example: TT or tt)
homozygous(hom-oh-ZY-gus)
covers up or masks other forms of the gene
dominant trait
gets covered up by other (dominant) forms of the gene
recessive trait
an individual that has a recessive trait but does not show it
carrier
a tool that follows the occurence of a particular trait in a family
pedigree
traits that are controlled by genes on the X or Y chromosome
sex-linked traits
