E: WHAT'S THE DIFFERENCE BETWEEN INCOMPLETE DOMWANCE AND CO-ODOMINANCE ? GIVE EXAMPLES OF THE BOTH INCOMPLETE AND
CO-ODOMINACE. USE THE PUNNET SQUARE TO SUPPORT YOUR ANSWER

Answer/Explanation:

Incomplete dominance is when one allele is not entirely dominant over the other, resulting in an intermediate phenotype. Example could be in flower colour. F is the allele for red flowers, f is the allele for white flowers. Let's cross a red flower (FF) with a white flower (ff):

         F               F

f        Ff              Ff

f        Ff              Ff

100% of the offspring are Ff. F is in completely dominant to f, so all the offspring have an intermediate phenotype - all the flowers are pink.

Co-dominance is when neither allele is dominant and both alleles are expressed equally. An example is in human blood types. A and B alleles are both dominant to the O allele, but co-dominant to each other. Therefore, if an individual who is AO has children with an individual who is BO:

           A                O

B        AB              BO

O        AO             OO

The individual would either be blood type O (OO), blood type A (AO), blood type B (BO) or blood type AB (AB)

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
