A couple is planning to have children. The male is heterozygous for huntingtons disease and homozygous dominant for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntingtons. Huntingtons disease is dominant over the normal condition(h), and the normal condition is dominant(T) over Tay-Sachs(t). Complete a punnett square for this cross and determine the phenotypic ratios for the couple having a normal child(no disease), Tay-Sachs but no Huntingtons, Huntingtons but no Tay-Sachs, and both Huntingtons and Tay-Sachs.

Can you please make a concept map with the main Idea as History of life. The words that are used are prokaryotes;eukaryotes;Fossils;Miller-Urey experiment; Redi: Pasteur; Needham; spontaneous generation; Biognesis; Paleozoic era; Mesozoic era; cenozoic era; Endosymbiosis; endosymbiotic theory; Cyanobacteria. After that is done can you make a connection key that show the connection for the relationship. Oh and sorry but can you label the lines as (A,B,C, and so on)
So it will start from A and show the connection to B. Thank you that is all if it can be done by today that would be great.
