Question

select the correct answer. if a biological child of tall parents has dwarfism, and one of the childs ancestors had dwarfism, which type of gene might have caused the childs dwarfism?

a. genotypic
b. phenotypic
c. recessive
d. dominant

Explanation:

Tall parents having a dwarf child suggests the trait is recessive. Recessive genes require two copies (one from each parent) to express; parents are likely carriers (heterozygous), passing recessive alleles. Ancestor with dwarfism supports recessive inheritance through carriers. Genotypic/phenotypic refer to genetics/traits, not gene types; dominant would need a parent to express the trait.

Answer:

C. recessive
