Genetics And Biological Determinants In The Development Of Humans

Abstract

Genetic determinism is the idea that genes have greater causative power than is generally accepted by scientists, and that genes are responsible for the development of features. Belief in genetic determinism is both an educational and social issue since it contradicts scientific knowledge and may contribute to the emergence of intolerance such as racism and prejudice against sexual orientation. Adapting occurs in biological systems in response to molecules and the molar surroundings. Genetic and neurological systems would thus be dynamic (cybernetic), in contrast to previous conceptualisations in which genes and minds are fixed in form and function.  We begin this article by looking at the core ideas of the genetically determined theory. In this cross-sectional, predicting correlation study, all 92 children aged 24 to 36 months who took part in the municipal preschool programme network in a municipality in the Jequitinhonha Valley region in 2011 were included. The socioeconomic profile was estimated using a questionnaire from the Brazilian Association of Research Companies (ABEP). To create the sociodemographic and mother and child health profile, a self-made survey was used.The indicator used to indicate growth was height-for-age. Using the Bayley Scale of Infant and Toddler Development, cognitive and linguistic development were evaluated. The Home Observation for Measure of the Environmental was used to evaluate the home environment, while the Infant/Toddler Environment Scale was used to evaluate the quality of educational settings. A self-made survey was used to evaluate the neighbourhood’s quality. A multivariate linear regression was used for the purpose of the research. Most of the households had parents with low levels of education and were from socioeconomic class D. Cognitive and language development were under average in 28.6% and 28.3% of patients, respectively, while stunted growth was seen in 14.1% of cases.  69.6% of homes were considered development-risky, and there were not enough educational institutions.The findings revealed that among the children who took part, stunting was very prevalent and their cognitive and linguistic development was below average. The relationship between growth and development and biological and environmental variables has been established. On the other hand, environmental factors were linked to development, whereas biological factors were more closely linked to development.
