In translocations, parts of chromosomes move to other, nonhomologous chromosomes or to other regions of the same chromosome. Translocations can affect the phenotype by causing genes to move to new locations, where they come under the influence of new regulatory sequences, or by breaking genes and disrupting their function.
-What is the outcome of a Robertsonian translocation?
A) Two acrocentric chromosomes
B) One metacentric chromosome and one chromosome with two very short arms
C) One metacentric and one acrocentric chromosome
D) Two metacentric chromosomes

Question

Quizplus · Accepted Answer

A Robertsonian translocation results in one metacentric chromosome and one chromosome with two very short arms, typically involving the fusion of two acrocentric chromosomes.
