test crosses, incomplete dominance, Codominance Flashcards
1
Q
How do we know if the dominant trait is homozygous or heterozygous?
A
Perform a test cross, using an unknown genotype with a homozygous recessive
2
Q
if you perform a test cross, and all the offsprings display the dominant phenotype then what is the parent?
A
Homozygous dominant
3
Q
if you perform a test cross and the offspring display, both dominant and recessive phenotypes then what is the parent?
A
Heterozygous
4
Q
what is incomplete dominance?
A
where neither allele is dominant making a blend of both parental traits
(ROAN)
5
Q
What is co dominance ?
A
both alleles are dominant and both traits show up
or
when two different alleles are fully expressed in a trait
6
Q
what does ROAN mean?
A
both colors/traits showing up
7
Q
what does ROAN mean?
A
both colors/traits showing up
