Page(s) 179-184 7.D Explain how kinship influences the distribution of altruism in primate groups. Which of the following statements about kin-relations in cooperatively breeding primates are true, and which are false? Drag each item on the left to its matching item on the right. Unrelated females help care for the young of the breeding female in order to prove that they will be a good parent. Cooperative breeding takes place more commonly among kin than among unrelated individuals. Sisters sometimes disperse together to form new groups, where one sibling acts as the dominant breeding female and the others help to raise young. Mate competition is greater among related females. Some species can pass their sibling's genes (along with their own) to their offspring. This makes cooperative breeding more beneficial. In a cooperative breeding scenario, subordinate females are able to produce offspring as readily as dominant females.

You will create a molecular clock model for an arthropod gene. follow these guidelines to make your model: . your timeline will span from 90 million years ago to the present. the common ancestor in your model is an arthropod that lived 90 million years ago. the gene that you'll track codes for a protein in the species venom . the dna sequence youll track contains 10 nitrogen bases. you can choose the order of the bases and where the mutations occur. this gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. to build your model,/ calculate the estimated time period it takes for 1 base pair to mutate. the first time period will only show the common ancestor. at the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences. the first and third descendant species will survive for the rest of the timeline. the second descendant species was extinct 50 million years ago. calculate how long it will take for one full base pair mutation to occur. explain your reasoning by constructing a mathematical equation
