Salutations! would you kindly me out on this question? the diagram shows embryo development of four different animals. how is this evidence to sugest that life changes over time? a: stiking similarites at early developmental stages is evidence that they came from a common ancestor. b: late-stage embyronic development illustrates how aacquired characteristics have caused these to become more differentiated over time. c: these stages indicate that animals within a species must have changed over time. d: the dna of all these life forms begins exaclty the same and then changes over time as it replicates to produce the orgainsms different traits

What are the types of mutations, and how does each alter the encoded protein? college level answer

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?
