Immunoglobulins that attach to and sensitize mast cells and basophils are
Ugo [173]

Answer:

IgE

Explanation:

Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.

They are known to be produced by produced by plasma cells (white blood cells).

Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.

In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.

explain how complete dominance, co dominance, incomplete dominance, and sex linked traits are inherited and expressed differentl
dlinn [17]
<span> COMPLETE DOMINANCE:
</span>
<span>Mendel concluded that some alleles are dominant and others are recessive. When one dominant allele is present, it's enough to make the recessive allele unexpressed (this is what happens in heterozygous individuals). In other words, it 'hides' or masks the recessive allele.

CO-DOMINANCE:

-a condition in which both alleles are dominant.
</span>
There are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB):  100% of the offspring being WB. With this genotype, they have black feathers and white feathers.
It's not a blend of colors, but a case where both are expressing.

INCOMPLETE DOMINANCE:
-a condition with none of the alleles is dominant or recessive, so the traits blend in the phenotype.

Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.

For example:
plant 1: RR -red
plant 2: rr- white

By crossing this plants we will obtain 100%  of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.

SEX LINKED TRAITS

Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.

In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents.
