Answers
Answer : In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. In animals, metameric segments are referred to as somites or metameres.
Metamerism is a phenomenon that occurs when two colors appear to match under one lighting condition, but not when the light changes. Metameric matches are quite common, especially in near neutral colors like grays, whites, and dark colors like these.
Feature of metacentric chromosomes
Metacentric chromosomes have their centromere in the centre of the chromosome, submetacentric have centromeres slightly off centre. Arcocentric chromosomes have long arms (q) and short arms (p) like submetacentric chromosomes, however the centromere is slightly higher leaving longer long arms and shorter short arms.
