Genotype
the
genetic
constitution of an organism (the
alleles
it has for a gene)
phenotype
the
expression
of the
genes
and its interaction with the
environment
homozygous
a pair of homologous chromosomes carrying the
same
alleles
for a single gene
heterozygous
a pair of
homologous
chromosomes carrying two
different
alleles
for a single gene
recessive allele
an allele only expressed if no
dominant
allele is
present
dominant
allele
an allele that will
always
be expressed in the
phenotype
codominant
both alleles are
equally
dominant
and expressed in the
phenotype
multiple alleles
more than
two
alleles for a
single gene
sex-linkage
a gene whose
locus
is on the
X chromosome
autosomal linkage
genes that are located on the same
chromosome
(not the
sex chromosome
)
epistasis
when one gene
modifies
or
masks
the
expression
of a different gene at a different
locus
monohybrid
genetic
inheritance cross of a
characteristic
determined by
one
gene
dihybrid
genetic
inheritance cross for a
characteristic
determined by
two
genes
