Use the drop-down menus to decide if an example of similar traits is likely a homologous structure or an analogous structure.
snow_tiger [21]

Answer:

- Bird wings and dragonfly wings are both used for flight: Analogous structure

- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure  

- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure  

- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure  

Explanation:

Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.

The ABO blood groups in humans are expressed as the I A , I B , and i alleles. The I A allele encodes the A blood group antigen,
Fynjy0 [20]

Answer:

d. multiple alleles and codominance

Explanation:

ABO blood group is controlled by three alleles instead of the usual two. Hence, it is an example of multiple alleles. These three alleles are IA, IB and i. IAIA genotype leads to production of A antigen hence A blood group. IBIB genotype leads to production of B antigen hence B blood group. When they are present together (IAIB) both A and B antigens are produced resulting in AB blood group. Hence ABO blood group is also an example of codominance.

Both IA and IB are dominant over the i allele. So IAi and IBi will produce A and B blood group respectively. ii genotype leads to O genotype.
