ch 10 Flashcards
Allele
one or more alternative gene
autosomal recessive
inheritance pattern of a recessive allele on an autosomal
codominance
mode of inheritance in which two alleles are fully expressed in a heterozygote
dihybrid cross
mating between two individuals that are heterozygous for two genes
diploid
cell that containing two full sets of chromosomes one from each parent
dominant
broadest (most inclusive) taxonomic category
f1
offspring of the p generation in a genetic cross
f2
offspring of the f generation on a genetic cross
genotype
an individuals combination of alleles for a particular gene
haploid
cell containing one set of chromosomes
heterozygous
possessing two different alleys for a particular gene
incomplete dominance
most of inheritance in which a heterozygous phenotype in intermediate between the phenotype of the two homozygous
monhybrid cross
mating between two individuals that are heterozygous for the same gene
phenotype
observable characteristics of an organism
pleitropy
multiple phenotypical effects of one generation
polygenic trait
caused by one of more trust
product rule
the chance that two independent events will both occur
punnet square
diagram that uses genotypes of the parents to reveal the the possible results of a genetic cross
recessive
allele whose expression is masked if a dominant allele is present
sex linked
describes genes ot traits on the X or Y chromosome
true breeding
always producing offspring identical to the parents for one or more traits
