|
Dominant alleles |
could be homozygous dominant could be heterozygous
if it is present, person will have that phenotype
some dominant traits are not expressed equally in all individuals with the trait. |
|
|
Recessive alleles |
always homozygous |
|
|
How are varying types of skin colors possible? |
codominance both phenotypes are expressed together in a heterozygote. this will result in three phenotypes |
|
|
Linked genes |
genes that are located on the same chromosome
inherited together more often than would be predicted by probability
|
|
|
Linkage group |
all of the genes on a given chromosome |
|
|
Crossing Over |
can separate linked genes and mix allele combinations |
|
|
Why do some phenotypes not show up if a person has those alleles or genes? |
variable expressivity: some dominant traits are not expressed equally in all individuals with the trait
environmental factors |
|
|
Segregation |
* Each gamete will receive one allele
|
