Please answer 17 and 18!!
Show transcribed image text People who inherit one copy of the Rb (retinoblastoma) gone that is normal and one copy that is mutated-that is, people who are heterozygous for Rb- have a greatly increased risk of cancer. Given this information, do you agree or disagree with the following statement? Explain your answer. The Rb mutation must have a recessive effect, which means that it must result in a decrease in Rb function. Thus. Rb in its mutant form must be a tumor-suppressor. Figure below shows a sequence of mutations that might underlie the development of colorectal cancer. Explain why the loss ol p53 is advantageous to cancerous cclls.
