Answer:

There are no options to this question, the options are:

A) Dominance

B) Recessive inheritance

C) Incomplete dominance

D) Sex-linked inheritance

The answer is D

Explanation:

Sex-linked inheritance is a kind of non-mendelian inheritance in which traits are transferred via genes on sex chromosomes. There are two sex chromosomes in humans namely: X and Y chromosomes. These traits that are inherited this way are called Sex-linked traits.

Since the Y chromosome is genetically inert, it does not contain any trait. Hence, traits can only be transferred on the X chromosome. Therefore, once a male or female receives the affected X chromosome, the traits will be expressed irrespective of whether it is dominant or recessive. Hence, the main way a recessive allele would be fully expressed even when only one copy is present would be via SEX-LINKED INHERITANCE.

</span><span>Cell membranes contain membrane proteins that  allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins. </span>
