7. PART 2^ Flashcards
new alleles arise at ____ through the process of?
anytime
mutation
***** define mutation
any change in nuclei of a gene
mutation happen __ the ___ and at a ___ process
all the time
random
if there is more than 1 allele in a population it is called __ type
wild
most frequent = ____ type and all other allies are called ___ alleles
wild
mutant
if will type is present less than 99% of the time the gene is called ____ this means?
polymorphic
many types
1individual can only have #__ alleles bc we have homologous pares of each chromsomes
2
when there are multiple allies It cannot be recessive or dominate so it show….. which means?
dominancy of hierarchy
multiple alleles
_______ dominance is where neither a allele is dominant or recessive and so ______(Rr) will have _____ _____
incomplete
heterozygotes
intermediate phenotypes
incomplete = ______ traits
intermediate
if the OG phenotypes reappear in F2 gen it means the alleles have…
NOT BLENDED
_______ = both alleles produce phenotypes present in offspring (both dominant/ both expressed)
codominance
ex of codominance is?
ABO blood type system
******* ABO blood type system is>
3 different alleles that code for blood type which is
A allele
B allele
O allele
O allele is recessive
A and B are codominant
the 3 alleles (A,B,O) produce
different versions of proteins that will determine what proteins are expressed at the surface of the cell
