The scientific study of inherited variation is called ___________?

Why study human genetics? Choose all that apply.

• to determine which diseases involve genetics

• to learn about basic biological functions from studying diseases

• to know more about humans

• to better understand human evolution

• to help us better understand alien life forms

How is this Quizziz going so far?

• Great!

• All right

• Not sure I am ready for this

• Oops, where are my notes?

What did transmission genetics study to understand inheritance?

• molecules

• cells

• traits

• organelles

Which of the following things were involved in all kinds cytologists research? (Hint: What does the word part cyto- mean?)

• cells

• organelles

• tissues

• organs

What were the limitations of earlier techniques like transmission genetics and cytology in understanding human genetic variation? Choose all that apply.

• DNA could not be studied directly

• Recessive, single gene mutations were difficult to study

• There were not enough humans do experiments on

• Humans reproduce too slowly for breeding experiments

Which molecular technique involves making lots of copies of one piece of DNA with primers, temperature cycles and DNA polymerase? Answer with acronym/abbreviation or full name, spelled correctly.

Which new molecular technique can test thousands of genes at a time, and involves making single stranded DNA, attaching it to a glass slide, and seeing which cells have mRNA/cDNA that stick to it?

Which of following answers best represents the genetic variation between any two humans who are not identical twins?

• 1 in 10 base pairs are different

• 1 in 100 base pairs are different

• 1 in 1000 base pairs are different

• 1 in a billion base pairs are different

Polymorphism literally means many shapes. What does it mean in genetics?

• base pair

• genetic differences

• genetically identical

• microarray
