|
genetics |
the study of heredity |
|
|
allele |
alternated versions of genes that account for variations in inherited characters |
|
|
monohybrid cross |
between 2 purebred parents with one differing characteristic |
|
|
dihybrid cross |
mating of parental varieties differing in 2 characters |
|
|
homozygous |
organism that has 2 identical alleles for a gene |
|
|
heterozygous |
organism that had 2 different alleles for a gene |
|
|
dominant |
alleles determine the appearance |
|
|
recessive |
alleles don't determine appearance |
|
|
law of segregation |
a sperm or an egg that carries only one allele for each inherited character because of the 2 alleles for character segregate2 from each other during the production of gamates |
|
|
genotype |
genetics makeup |
|
|
phenotype |
physical appearance |
|
|
locus |
specific location of a gene along the chromosome |
|
|
law if independent assortment |
the inheritance of one character has no effect on the inheritance of another |
|
|
test cross |
mating between an individual of a dominant phenotype and a homozygous recessive individual |
|
|
wild type trait |
seen in nature not necessarily dominate |
|
|
incomplete dominance |
f1 hydride have an appearance between the phenotype of both parenys |
|
|
codominance |
both alleles are expressed i.e. AN blood type |
|
|
linked genes |
located near each other on the same chromosome. Tend to travel together during meiosis and fertilization. Each block is inherited as a set and therefore do not follow Mandela law |
|
|
sex linked genes |
located on the sex chromosome x |
