What is studied in fruit flies that relates to humans?
The fruit fly is a stand-in for humans, and allows investigation of the molecular mechanisms of 26 human diseases, including ALS. Researchers could use Drosophila melanogaster, because it is a well-established model organism to understand the molecular mechanisms of many human diseases.
Which pattern of inheritance controls the equal expression of two traits in an organism?
A variation on incomplete dominance is codominance, in which both alleles for the same characteristic are simultaneously expressed in the heterozygote. An example of codominance is the MN blood groups of humans.
Why is it not possible to study the pattern of inheritance of traits in human beings?
Answer : It is not possible to study the inheritance pattern of traits in human beings; the same way as it is done in pea plant because, the pea plant undergoes self-pollination in every generation thereby keeping it pure. That is control crosses cannot be performed in humans.
Why are fruit flies used in genetic research?
Fruit flies have a very simple genetic structure, which makes them ideal for genetic research. It is useful to study mutant fruit flies, as their quick reproduction rate allows scientists to observe the advantages and disadvantages of certain mutations.
Why do we study fruit flies to understand genetics name three common reasons why?
Why it is not possible to study the pattern of inheritance?
What is the inheritance pattern associated with the ABO blood type in humans?
The ABO blood type is inherited in an autosomal codominant fashion. The A and B alleles are codominant, and the O allele is recessive.
Why control crosses are not possible in human beings?
Reason :- The controlled crosses that can be perfoemed in pea plant or same other organism, are not possible in case of human beings. Reason :- The controlled crosses that can be perfoemed in pea plant or same other organism, are not possible in case of human beings.”
