What is the principle of Dominance?
|
when two forms of the same gene are resent the daminant allele is expressed.
|
|
|
What is the principle of Segrigation?
|
if meiosis two alleles saparate so that each gamete gets only one form of the gene.
|
|
|
What is the law of independent assortment?
|
Each trait is inherited independent of the other traits.
|
|
|
What is teh difference between a phenotype and a genotype?
|
a phenotype refers to observable traits, a genotype is the specific arrangement of alleles for a trait.
|
|
|
What is an Allele?
|
two or more alternate forms of a gene.
|
|
|
What is meant by the term "hemozygous"?
|
homozygous refers to a genotype that contains the same alleles for a trait.
|
|
|
What is meant by the term "Heterozygous"?
|
a genotype that contains different alleles for a trait.
|
|
|
Explain the difference between mononhybrid and dihydrid.
|
momonhybrid is describing one trait. dihydrid is describing two traits.
BONUS: mono means one, hybrid menas combined. |

|
|
What is the purpose of a test cross?
|
to determine the genotype of an individual with the dominant phenotype.
|
|
|
Define the term "intermediate inheritance"
|
a blend of multiple phenotypes
|
|
|
Define "condominance"
|
two phenotypes both appearing at the same time.
|
|
|
What is complementary interaction?
|
wehn two genes interact to produce a phenotype where neither is able to produce itself.
|
|
|
What is supression epistasis?
|
when one gene masks the expression of another gene.
