This change that occurs with X inactivation can be related to non-genetic influence, can be inherited not changing in the sequence of the DNA.

tatiyna

At this stage of development, children are still highly literal and concrete in their thinking, but they become much better at applying logic. Kids get better at considering how other people might see a situation as they progress through the stages, and the egocentrism of the earlier stage starts to fade.

<h3>What is concrete operational stage in child development ?</h3>

Between the ages of 7 and 11 or 12, when a child is in the third stage, or the concrete operational stage, they start to think logically and start classifying objects based on their similarities and differences. The toddler also starts to understand the notions of time and number during this time.

  • According to Piaget, logical operations like conservation, reversibility, or classification, which enable logical reasoning, characterise thinking at this stage.
