The animal Mischievous gremlins comes in three coat-color varieties
The animal Mischievous gremlins come in three coat-color varieties: black, red, and striped (which consists of a mixture of black and red patches). The famous scientist Johnny Nerdelbaum Frink decided to investigate the hereditary basis of the Mischievous color variation. He carried out the following three crosses: Cross Offspring Striped Striped Striped Black Striped Red 16 striped, 5 black, 3 red 6 striped, 7 black 18 red, 9 striped, 6 black a. After analyzing these results, Professor Frink proposed a hypothesis to explain the inheritance of color in this animal. He assumes the presence of two loci which are under some type of epistasis. Explain this hypothesis. b. For the first two crosses, he tested this hypothesis by using a chi-square test. What would his tests look like? Striped Offspring Black Observed Numbers (0) Expected Numbers (E) O-E (O – E)² (O – E)²/E df P value = Therefore, the null hypothesis is: rejected not rejected x² = || TOTAL 13 13 (Choose one) Striped Offspring Black Red Observed Numbers (0) Expected Numbers (E) O-E (O – E)² (O – E)²/E df = P value = Therefore, the null hypothesis is: rejected not rejected TOTAL 24 24 = (Choose one)
