ESTIMATE OF HYBRID VIGOR IN STATURE IN THE RESIDENT POPULATION IN THE MUNICIPALITY OF CAZENGA

Abstract

The present work was carried out with the objective of estimating the hybrid vigor in the resident population in the municipality of Cazenga in individuals between the ages of eighteen and twenty three years and the choice of location was due to a direct observation of the population existing in that region, we specifically used the administration as a center of data collection, since there is a high frequency of individuals coming from different regions of the municipality in question. Data collection was done using each individual's identity card information and in many cases we used a tape measure to estimate the height of those individuals who were not identified during data collection. There was a greater difficulty in collecting data from the parents along with their descendants, and vice versa, on many occasions we had to address the residence of both parents for completeness of data. The total sample consisted of 696 individuals, of whom 462 were progenitors, 231 for females and the same for males, and the remaining 231 were hybrids. Statistical parameters were used to estimate the hybrid vigor as the mean, variance, coefficient of variation, standard deviation, and the normal distribution curve. We also used genetic tests such as the genetic diversity of Nei, and the Hardy and Weinberg Balance Test and Heritability. It was found that from the period 1960-2018 males in the municipality of Cazenga grew by 3.4 centimeters from 169.5 centimeters to 172.8 centimeters, while females grew 1.3 centimeters from 166 centimeters to 167.9 centimeters . Overall the new generation average has grown from 168.0763 centimeters to 170.4277 centimeters, due to an average force increase of 2.351431 centimeters.
