8 mendelian inheritance Flashcards
1
Q
mendel’s three laws
A
segregation
independent assortment
dominance
2
Q
segregation
A
each gamete only receives one allele for a characteristic
2 alleles total per trait
3
Q
indipendent assortment
A
different traits are inherited at random and does not depend on inheritance of other alleles
4
Q
dominance
A
some alleles are more powerful than others (dominant) and always have an effect on the offspring
5
Q
exceptions to mendel’s rules
A
- incomplete dominance (neither is dominant so they merge to make a phenotype)
polygenic inheritance- many genes for one phenotype
codominance
6
Q
codominance definition
A
when both alleles affect the phenotype
e.g. blood type
7
Q
codominance in blood type
A
AB are codominant
s when heterozygous both phenotypes are shown
O is recessive
