Il existe [des] facteurs multiplicateurs ou éliminateurs de gènes dont les effets, pratiquement aléatoires, ne peuvent être prévus tout au moins quant à leur direction. Ces facteurs dispersifs provoquent ce que l'on appelle une dérive génétique aléatoire et sont essentiellement liés à la taille des populations mendéliennes. 1, record 1, French, - d%C3%A9rive%20g%C3%A9n%C3%A9tique%20al%C3%A9atoire

Hay dos tipos de muestras que se utilizan en los estudios: muestras probabilísticas y no probabilísticas. Las no-probabilísticas se basan principalmente en el juicio de expertos y se estudian en cursos especiales de muestreo. De las probabilísticas hay 4 tipos y se basan en la selección aleatoria. Para llevar a cabo una selección aleatoria se pueden utilizar varios instrumentos que garanticen que la selección sea al azar. Puede ser: tirar una moneda al aire; sacar nombres de una urna; utilizar una tabla de números aleatorios; utilizar un programa computadorizado para hacer la selección. 3, record 2, Spanish, - selecci%C3%B3n%20aleatoria
