Resumen
Se compararon diferentes aspectos de las asociaciones sateliticas, presentes en dos grupos de 200 células cada uno (2 por individuo), correspondientes a 100 madres post-parto, con edades comprendidas entre 14 y 43 altos y 100 neonatos (51 hombres y 49 mujeres), provenientes de la población de Puriscal, Costa Rica. Varios tipos de asociaciones sateliticas mostraron una proporción significativamente mayor en las madres. Las asociaciones más frecuentes en los dos campos fueron las de dos cromosomas, seguidas frecuencia por las de tres cromosomas. La relación D/G fue de 1,43 en los niños y de 1,40 en las madres; el numero de asociaciones por Mule fue casi el doble en las madres; el numero medio de acrocéntricos por asociación fue de 2,2 en los niños y de 2,35 en las madres. No se reveló diferencias significativas entre los valores observados y esperados de cromosomas 13 y G involucrados en asociaciones en ambos grupos, de manera que los factores no determinados aun, implicados en el aumento de asociaciones sateliticas en las madres, influenciaron de manera similar a los dos tipos de cromosomas acrocéntricos.
Different features of the satellite associations between the acrocentric chromosomes of 100 postpartum mothers, between 14 and 43 years of age, and 100 neonates (51 males and 49 females) from Puriscal, Costa Rica, were compared (400 cells were examined, 2 from each individual). Several types of satellite associations showed higher frequencies in the mothers than in the neonates. The associations most frequently_ found in the two groups were those of two chromosomes, followed by those of three chromosomes. The ratio was 1.43 in the children and 1.40 in the mothers, The number of associations per cell in the mothers was almost twice that of the children. The mean number of acrocentric chromosomes per association was 2.2 in the children and 2.35 in the mothers. No significant difference was found between observed and expected values of D and G chromosomes in the two groups. Thus the probable factors responsible for the increase of satellite associations in the mothers similarly influenced the two types of acrocentric chromosomes.
