The therapy-treated cancer cells are labeled RED and the untreated, control cancer cells are labeled GREEN. If the therapy is effective, you would expect which of the following with regards to p53 expression:

Use the following pedigree for dwarfism to answer the questions below. Based on your understanding of inheritances is the trait dominant or recessive? Is it autosomal or sex-linked? Defend your answers. What is the genotype and phenotype for the following individuals:                        II-1  ___________­­­­­­­­­­­­­­­­­____________               II-3  _______________________     Individual III-4 marries her 1st cousin III-1 (YIKES), and is soon pregnant.

He is furious because they have a ‘tall’ child (not affected) and is accusing his wife of sleeping with his brother (III-3). Is his anger justified? Show your evidence.

A little girl was recently been diagnosed in kindergarten with an autosomal recessive disease known as Batten disease. Unfortunately, there is no known cure and she is not expected to live past her 20’s. She has a 5 year old brother has none of the signs of Batten disease her sister had while she was young. What is the probability that the brother is a carrier?
