Drag each tile to the correct box. What is the correct sequence of events in the history of molecular cloning?
Ian Wilmut and Keith Campbell transferred
nuclei from laboratory-cultured cells into
sheep egg cells without a nucleus, which
led to the birth of two lambs.
Hans Spemann showed that the transfer
of a cell’s nucleus to another cell without
a nucleus results in the formation of a
whole new organism.
Steen Willadsen created a genetically
modified egg by transferring the nucleus
from an early embryonic lamb cell into it,
which eventually developed into a
lamb embryo.
Hans Spemann found that one could
split an early two-celled embryo to form
two separate and complete organisms.
Robert Briggs and Thomas King found
that a frog egg receiving the nucleus from
an early tadpole embryo developed into a
tadpole.

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?
