hetrozygous
|
having two different alleles for a given gene
|
|
|
homozygous
|
having the same allele for a given gene
|
|
|
recessive allele
|
an allele that has no noticeable affect on the phenotype of the gene when the individual is heterozygous for that gene
|
|
|
dominant allele
|
an allele that determines the phenotype of a gene when the individual is heterozygous for that gene
|
|
|
genotype
|
the genetic make up of an organism
|
|
|
phenotype
|
the expressed traits of an organism
|
|
|
monohybrid cross
|
an experimental mating of individuals differing at one genetic locus
|
|
|
dihybrid
|
an experimental mating of individuals differing at two genetic loci
|
|
|
mendals law of segregation
|
pairs of alleles separate/segregate during gamete formation
|
|
|
mendals law of independent assortment
|
each pair of alleles segregates independently of other pairs of alleles during gamete formation
|
|
|
Dominant and Recessive disorders
|
are inherited through genetics
|
|
|
incomplete dominance
|
a type of inheritance in which the pheneotype of a hetrozygote is intermediate between the phenotypes of the two types of homozygotes
|
|
|
codominant
|
inheritance pattern in which a heterozygote expresses the distinct trait of both alleles
|
|
|
pleiotropy
|
the control of more then one phenotypic characteristic by a single gene
