|
Law of Segregation |
every organism has 2 alleles of each gene and when sex cells are produced, the alleles separate |
|
|
Law of Independent Assortment |
genes for different traits are inherited independently of each other and with equal opportunity for either |
|
|
heredity |
the passing of characteristics or traits from parent to offspring |
|
|
genetics |
the study of heredity |
|
|
true breeding |
another name for self pollinating; result in offspring that are genetically identical to the parent |
|
|
hybrid |
same as heterozygous; offspring come from parents that have different forms of traits |
|
|
genes |
a factor of heredity that is passed from parent to offspring |
|
|
allele |
different forms of a gene |
|
|
phenotype |
the physical appearance of an organism |
|
|
genotype |
the genetic makeup of an organism; the 2 letter allele combination for an organism's trait |
|
|
dominant |
a trait that will appear in the offspring if at least one of the parents contributes an allele for it |
|
|
recessive |
trait that can be carried in a person's genes without appearing in that person; must have 2 recessive alleles to show the trait |
|
|
homozygous |
where the two alleles for a trait are the same (BB or bb) |
|
|
heterozygous |
where the two alleles for a trait are different (Bb) |
|
|
punnett square |
tool used to determine the probability of a genotype in offspring |
