Content: How are traits passed through the generations? Each parent passes on half of their DNA to their offspring. DNA is the code that determines how every single thing in the body is built. So each offspring gets the instructions for half of their body building plan from the mother and half from the father. Should a person have rights to their organs and tissues
Yes
How are pedigrees used to track diseases? They show traits over many generations so they can track a certain disease by noting a person as affected, carrier, or normal
Why does sickle cell disease run in families, yet is not present in every generation? Because it is recessive
How can doctors and genetic counselors calculate the probability of a child inheriting a disease? Punnett Squares using the parents genotypes
How does the presence of malaria in a region affect the frequencies of normal versus sickle cell
alleles? Sickle cell anemia confers a sort of immunity against malaria. That's because malaria reproduce in red blood cells (erythrocytes), and with sickle cell, the RBCs are misshapen, so the malaria does not thrive as well.
