an individual, produced 25-offspring with his normal-eyed wife. Of their children, 14 were heterochromatic and 11 were-normal. Calculate the chi-square value for this observation. x² = Identify the statement that best interprets the results of the chi-square analysis. Refer to the chi-square distribution table to identify the statement that best interprets the chi-square results. t is not unusal that a heterozygous man produced 14 out of 25 offspring wi heterochromia. The total number of normal offspring is significantly lower than expected. It is unusual that a man with heterochromia had 14 out of 25 offspring with heterochromia. There is a significant difference between the observed number of offspring with heterochromia and the number of offspring that were expected to have heterochromia.
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
