In establishing paternity by DNA fingerprinting,what proportion of microsatellite repeat alleles in a child come from the father?
A)only ones on the X chromosome
B)1/4
C)1/2
D)3/4

Question

Quizplus · Accepted Answer

Each human has two copies of each autosomal chromosome, one from the mother and one from the father. Therefore, half of the child's microsatellite repeat alleles come from the father. The alleles on the X chromosome also come from the father, but since the question specifies "repeat alleles," which are found on autosomal chromosomes, A is incorrect. B and D are also incorrect as they represent fractions that do not accurately reflect the genetic contribution of the father to the child's microsatellite repeats.
