A. a person with dwarfism who has autosomal dominant achondroplasia born to parents of normal height.
B. some cases of severe blood infections.
C. a new mutation in which a child has a condition that no other relative has.
D. a child with an autosomal recessive condition who has one wild type parent and one carrier parent.

Answer 1

Uniparental disomy explains the occurrence of a child with an autosomal recessive condition who has one wild type parent and one carrier parent.

Step-by-step explanation:

A child with an autosomal recessive condition who has one wild type parent and one carrier parent can be explained by the concept of uniparental disomy. Uniparental disomy occurs when an individual inherits two copies of a chromosome or part of a chromosome from one parent, instead of one copy from each parent. In this case, the child has inherited two copies of the autosomal recessive allele, resulting in the expression of the recessive condition.
