    Below is a simplified phylogenetic tree showing relationships among some reptiles:                                 ┌─Gecko                  ┌───┤                  │         └─Anole      ┌───┤      │         │                    ┌─Skink      │         └───────┤      │                                └─Monitor Lizard──┤      └─────────── Iguana Rank the following species from most closely related to skinks to most distantly related to skinks. If two species are equally related, overlap them. In the answer selections, each rank is listed in order, with levels separated by commas.

A geneticist is investigating the inheritance of flower color in a population of plants. According to Mendelian genetics, the expected phenotypic ratio for a dihybrid cross is 9:3:3:1 (9 individuals with PT1, 3 with PT2, 3 with PT3, and 1 with PT4). After conducting a dihybrid cross, the geneticist observed the following results: PT= Phenotype PT1: 210 individuals PT2: 70 individuals PT3: 80 individuals PT4: 40 individuals Calculate the chi-square value to determine if the observed phenotypic distribution deviates significantly from the expected ratio.
