Incomplete Codominance and complete dominance

Question 1

What is Incomplete Dominance?

Answer 1

Incomplete dominance describes a condition in
which both alleles are partially expressed and both alleles blend in to create a new phentotype.

Question 2

Therefore a heterozygous
offspring will demonstrate a…

Answer 2

A phenotype somewhere
between the dominant
trait and the recessive
trait.

Question 3

When representing incomplete dominance..

Answer 3

Upper and lower-case letters are not used, since neither allele is dominant over the other. Therefore, we need to use SUPERSCRIPTS.

Question 4

What is codominance?

Answer 4

Codomanince is a
situation in which both
alleles are fully expressed.

Question 5

Example of codominance?

Answer 5

For ex. a cow. One allele is
expressed in the white
hairs and the other in the
black hairs.

Question 6

What is sickle cell anemia?

Answer 6

Sickle cell anemia occurs due to the
hemoglobin allele which causes a shortage in RBC.

Answer 7

Hb^a

Question 8

Answer 8

Hb^s

Question 9

For those individual who are homozygous (HbsHbs) have….

Answer 9

Sickle cell anemia

Question 10

What is an example of an example of heterozygous
advantage.

Answer 10
