उत्तर
The genetic basis of development refers to how inherited traits from parents influence a person’s growth and characteristics. Genes, which are made up of DNA, carry instructions that determine features like height, eye color, intelligence, and even behavior. These genes are located on chromosomes, with humans having 46 in total, 23 from each parent. While some traits are controlled by single genes, others result from the combined influence of many genes.
Development is not determined by genetics alone. The environment plays a key role in how genetic potential is expressed. For example, a child may inherit the potential to be tall, but poor nutrition can prevent them from reaching that height. Similarly, while genetic disorders like Down syndrome affect development, environmental support can help manage their impact.
In summary, genes set the foundation for development, but it is the interaction with environmental factors that ultimately shapes how a person grows and behaves.
