Question

Which of the following pais is wrongly matched?

• A. Haplodiloid sex-determination $\to$ Honey bees
• B. Pleiotropy $\to$ Phenylketonuria
• C. Codominance $\to$ Sickle-cell anaemia
• D. Control cross $\to$ Performed in human being

Answer 1

The correct option is D Control cross $\to$ Performed in human being

In genetics, a test cross, first introduced by Gregor Mendel, is used to determine if a group exhibiting a dominant trait is homozygous or heterozygous for that trait. test crosses determine the genotype of an individual with a dominant phenotype. So the wrongly matched option here is "Control cross → Performed in a human being".
