Which statement about the specific immune response is FALSE? O Each T or B cell has antigen receptors for only one specific antigen.
O Tand B cells recognize antigens by using antibodies bound to their surface membranes.
O Unique antigen receptors are created by genetic recombination.
O Antigens must be presented by an MHC molecule for T and B cells to recognize them.
O All cells express MHC-I molecules, but only antigen-presenting cells express MHC-Il molecules.

In some plants, pointed leaves (p) are dominant over rounded leaves (p). a plant with a genotype of pp

Approximately 90% of all cases of polycystic kidney disease are inherited in an autosomal dominant fashion. the disease is typically related to mutations to genes (pkd1 and pkd2). pkd genes can be found on chromosome 16. the disease occurs in approximately 1: 800 to 1: 1000 people. here is a hypothetical example. the dominant allele d will cause the development of pkd. the recessive allele is known as d. what genotypes would correspond to suffering from pkd? dd, dd what genotypes would correspond to being normal (not suffering from pkd)? dd consider that 1: 1,000 people have pkd in your population of 325million. consider that pkd is inherited in an autosomal dominant fashion. show you math for all of the following questions: what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is p? what is q? how many people in your population would have pkd?
