Reason for Mendelian's success
|
-worked with a favorable organism (pea plants)
-used very large amounts of plants -used pure strains of plants -able to polinate plants -used math and probibility -studied one trait at a time -chose traits carefully -lucky |
|
|
gene
|
a sequence of DNA that controls the expression of a trait
|
|
|
allele
|
a different form of a gene for a trait
|
|
|
homozygous
|
both alleles are the same
|
|
|
heterozygous
|
both alleles are different
|
|
|
pure
|
both alleles are the same
|
|
|
hybrid
|
both alleles are different
|
|
|
chromosomes
|
rod-shaped structure in nucleous carrying genes
|
|
|
dominant
|
gene that controls a characteristic
|
|
|
recessive
|
lower case, must be both,
|
|
|
genotype
|
enetic make up of an organism
|
|
|
phenotype
|
the way an organism appears
|
|
|
law of dominance
|
some alleles are always expressed, some are not
|
|
|
law of segregation
|
if an orgainism has 2 different alleles each allel is inhereted seperatly
|
|
|
law of independent assortment
|
in a dihybrid cross the alleles for each trait are inhereted seperatly
|
|
|
incomplete dominance
|
the hybrid condition gives you a third phenotype
the 4:00 flower |
|
|
co-dominance
|
both traits are expresssed
hourse hairs |
