Which is an example of codominance? (1 point)
Dafna11 [192]

Answer:

roan coat color in horses

Explanation:

Codominance is one of the Non-mendelian inheritance patterns in genetics i.e. does not follow Mendel's principles of inheritance. Codominance is a phenomenon whereby an allele is neither dominant nor recessive to another in a gene i.e. one allele is not phenotypically expressed over the other. Hence, both alleles are simultaneously expressed in their heterozygous state.

An example of codominance is the roan coat color in horses where the colored (B) and white (W) alleles are both dominant in the coat color gene, hence, the horse expresses both black and white coat phenotypes known as ROAN (BW). The black and white alleles are said to be CODOMINANT.

Semipermeable cell membranes are made of phospholipids that form a bilayer. What major benefit does this arrangement of the memb
Andrej [43]

Answer:

The correct answer would be c. The cell has a greater level of structural support.

Phospholipds are the structural units of a cell membrane. They are consist of two components; hydrphobic lipids and hydrophylic polar heads.

They make a bilayer structure in which polar heads are in contact with water and lipid part are embedded within the layer.

  • Lipid bilayer gives the rigidity or shape to the cell.  
  • It isolates the cell from the sorroundings.
  • It is semi-permiable in nature and thus prevents or control the movement of substances across the membrane.
  • Being liquid in nature, the cytoplasm would have dispersed in the surrounding in absence of cell membrane.

Hence, most appropriate choice would be c. The cell has a greater level of structural support.
