Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...

Behavioral Genetics and Its Designs

Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Area of Science:

  • Genetics
  • Audiology
  • Public Health

Background:

  • A village in Jammu and Kashmir, India exhibits a notably high prevalence of deaf-mutism.
  • This condition impacts a significant portion of the local population.

Purpose of the Study:

  • To investigate the prevalence and underlying causes of deafness in a specific village population.
  • To analyze the genetic and environmental factors contributing to hereditary deafness.

Main Methods:

  • A cross-sectional study was conducted involving 79 individuals diagnosed with deafness.
  • Methods included pedigree analysis, audiometry, imaging, and molecular analysis to identify causes.

Main Results:

  • A high rate of hereditary deafness was identified, with 79 individuals suffering from non-syndrome deafness.
  • The prevalence was significant within a total village population of 2452 individuals.

Conclusions:

  • Intermarriage patterns within the village have contributed to the high prevalence of deafness.
  • Genetic factors, particularly non-syndrome deafness, are a major concern in this isolated community.
