inheritance Flashcards
genotype
all of the alleles an organism carries on its chromosomes
phenotype
observable characteristics that are a result of the genotype and the environment
mono hybrid
when a phenotype or trait is controlled by a single gene
dihybrid
when two characteristics are studied and are determined by 2 different genes
codominance
when two phenotypes are expressed
sex linkage
the expression of an allele dependant on the gender of the individual
autosomal linkage
two or more genes are on the same autosomal chromosome
epistasis
the interaction of different loci on the gene. one gene locus effects the other
why the ratios may not be as expected
random fertilisation of gametes
small sample size
statistical error
crossing over
