- A gene that influences coat color in domestic cats is located on the XX chromosome. A female cat that is heterozygous for the gene (XBXOXX) has a calico-colored coat. In a genetics experiment, researchers mate a calico-colored female cat (XBXOXX) with an orange-colored male cat (XOYXY) to produce an F1F1 generation. The researchers record observations for the cats in the F1F1 generation and plan to use the data to perform a chi-square goodness-of-fit test for a model of XX-linked inheritance. The data for the chi-square goodness-of-fit test are presented in Table 1.Table 1.

Which of the following statements best completes the chi-square goodness-of-fit test?AThe null hypothesis can be rejected because the chi-square value is greater than the critical value.BThe null hypothesis can be rejected because the chi-square value is less than the critical value.CThe null hypothesis cannot be rejected because the chi-square value is greater than the critical value.DThe null hypothesis cannot be rejected because the chi-square value is less than the critical value.
