Which of the following would be true of a plant heterozygous for a single gene controlling flower color? (assume complete dominance).
a) it will produce gametes with recessive flower color alleles and gametes with dominant flower color alleles in about a 3: 1 ratio.
b) it displays the recessive flower color.
c) if crossed with another heterozygous plant, the majority of progeny will have the dominant flower color.
d) about half of all its progeny will display the recessive flower color.

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?
