This would be a recessive disease.
Father is dd
Mother is Dd (has to be because one child has the disease)
Parents cross is dd x Dd which gives rise to Dd (0.5) and dd (0.5). Each time they have a child they have a 50% chance of the child having the disease. In their case, only one of their 3 children is dd. The others though are carriers!
To act as a catalyst in chemical reactions
Answer:
<u>1. type IV hypersensitivity: delayed-type hypersensitivity. </u>
<u>2. type I hypersensitivity: IgE </u>
<u>3. type II hypersensitivity: IgG </u>
<u>4. type III hypersensitivity: immune complexes </u>
Explanation:
Type IV hypersensitivity is cell mediated hypersensitivity rather than antibodies as in all other types of hypersensitivities. It is also known as delayed type hypersensitivity because it usually respond in 2-3 days via T-Lymphocytes rather than antibodies like IgE or IgG. So we can say that in option 5 is mismatched as it relates type IV to IgG antibodies.
