In a Gecko population a group of Geckos skin color is controlled by one gene with two alleles "R"which codes for red and is dominant to "r" which codes for yellow and is recessive. If 100 Geckos are on the island and you gene test them to know their alleles you'll observe that 30 are homozygous red, 60 are heterozygous red, and 20 are homozygous recessive. Determine the Chi-square. assuming the original parents (Rr xRr).* Hint: determine the expected first before plugging into the equation 111 13 5 11 4

Introduction:
- The chi-square (χ²) statistic is used to detect whether or not there is a statistically significant discrepancy between observed and predicted frequencies in a population.
- It is frequently used in hypothesis testing to assess the independence of two category variables.
- The test yields a chi-square statistic, which is compared to a critical value from a chi-square distribution to estimate the possibility of finding the difference between the predicted and observed frequencies by chance.
