Question: What phenotypes and ratios did you observe in the F1 generation? Question: Based on what you know about Mendelian genetics, did the F2 generation demonstrate the phenotypic ratio that you expected? If not, what phenotypic ratio was obtained with this cross, and why? Question: Describe the phenotypes obtained in the F2 generation. […]

1) The following pedigree shows transmission of galactosemia, a rare autosomal recessive disease caused by the inability to metabolize the sugar galactose, resulting in muscle, nerve, and kidney malfunction. i) Write genotypes for as many individuals in the pedigree as possible. Write each genotype below the corresponding symbol in the […]

When Thomas Hunt Morgan conducted dihybrid crosses with his fruit flies, which of the following made him realize that the two genes he was observing were linked, or inherited together as a group? a)The dihybrid F ratio was close to a 3:1 ratio. b)The dihybrid F ratio followed Gregor Mendel’s […]

What is the whole exome sequencing and how is it done? Give two specific examples of the use of whole exome sequencing to identify the specific genetic cause of a human genetic disease. I haven’t found much information but what I have found is that this method sequences only the […]
