Males are usually affected greater by sex-linked traits than females.
This is because


A) A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents.


B) A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny.


C) A dihybrid cross involves organisms that are heterozygous for two characters and a monohybrid only one.


D) A monohybrid cross is performed for one generation, whereas a dihybrid cross is performed for two generations.


E) A monohybrid cross results in a 9:3:3:1 ratio whereas a dihybrid cross gives a 3:1 ratio.


Answer:

C) A dihybrid cross involves organisms that are heterozygous for two characters and amonohybrid only one.
