What is predetermined epigenesis and give 3 examples to illustrate you understand the concept

Solution

Predetermined epigenesis: this is defined as the expression of the physical traits and behaviours in the phenotypes based on the genes with unfolding of genetic blueprint. Therefore, genes are main core determiners of phenotypic features

Example-1: Nature and environmental cues determine specific phenotypic predetermined epigenesist, where animal species is going to know about the specific trait or action before as per genetic blue print

Example-2: phenotypic plasticity & robustness in twins when they grow in different family environments exhibit, predetermined epigenesist as per environmental cues

Example-3: predetermined developmental stages can be observed in maze dull and maze bright in normal rearing conditions. This is because genes have meticulous role in identifying maze dull and maze bright rats as per inheritence.
