Unit 7: Notes 3 - Incomplete and Codominance

Question 1

What is Mendelian Genetics?

Answer 1

the inheritance of traits that are dominant or recessive and follow a “one or the other” pattern.

Question 2

What is complete dominance?

Answer 2

The pattern where the recessive trait is masked by the dominant trait.

Question 3

What is Non-Mendelian Genetics?

Answer 3

the inheritance of traits that have a more complex pattern than those outlined by Mendel’s Laws, where there is only one gene and complete dominance.

Question 4

What is codominance?

Answer 4

when two alleles for a given characteristic are both fully expressed, both dominant. This makes a third phenotype. (THEY ARE BOTH SEPARTED EXPERESSED)

Question 5

What would the genotypes in a codminance pattern look like?

Answer 5

Genotypes
RR
RW
WW

Question 6

What is incomplete dominance?

Answer 6

the pattern where two alleles for a give characteristic are both partially expressed. Neither allele is dominant so a blend of two results. So, red and white are incomplete dominace, so it will be pink together.
