génállománya

Génállománya refers to the gene pool of a species or population. It encompasses the total collection of genes and their various alleles within a breeding population at a given time. The size and diversity of a génállománya are critical factors influencing a population's ability to adapt to environmental changes. A larger and more diverse génállománya generally provides a wider range of traits, increasing the likelihood that some individuals will possess advantageous characteristics in the face of new challenges, such as disease or climate shifts.

Conversely, a small or inbred génállománya can lead to a reduction in genetic diversity. This lack of variation makes the population more susceptible to diseases, environmental stressors, and may result in an increased incidence of genetic disorders due to the higher probability of recessive alleles being expressed. Evolutionary processes like natural selection, genetic drift, mutation, and gene flow all act upon the génállománya, shaping its composition over time. Understanding a species' génállománya is therefore fundamental to conservation efforts, as it informs strategies for maintaining genetic health and ensuring long-term survival.
