Complex Patterns of Inheritance Flashcards
Mendel’s studies showed that Alleles are…
either dominant or recessive
Homozygous dominant and Heterozygous both show what phynotype?
dominant
the heterozygote shows the phenotypes of both the alleles
Codominance
Homozygous recessive show what phenotype?
recessive
a gene with more than two alleles
Multiple Alleles
Do Mendel’s patterns of inheritance work for every situation?
NO
Having many alleles for eye color that exist in the human population is en example of…
Multiple Alleles
What are four more complex ways organisma inherit a trait?
Incomplete dominance
Codominance
Multiple Alleles
Polygenic Traits
What are the alleles for blood type?
A, B, O
one allele is NOT completelt dominate over the other allele
Incomplete Dominance
Human blood type is an example of…
Multiple Alleles
The phenotype in incomplete dominance is ______ the homozygous phenotypes
internediate (somewhere inbetween)
How many blood type alleles does each person have?
2 (one from mom & one from dad)
what are the possable genotypes to the A phenotype?
AA, AO
what are the possable genotypes to the B phenotype?
BB, BO
what are the possable genotypes to the AB phenotype?
AB
what are the possable genotypes to the O phenotype?
OO
traits controlled by two or more genes
Polygenic Traits
Humans having variety of skin colors is an example of…
polygenic traits
