The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a
beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The
individuals are hence able to survive and
reproduce more than those individuals without the mutation. There is, therefore, a genetic
shift in the population in favor of the resistant genotype. After generations, the
whole population becomes antibiotic resistant.
Batteries cause problems in all BUT one way. That is
radiation. If batteries come to its expiration date, its chemicals, especially
the harmful ones will spread in the atmosphere and create pollution to its
environment. That is the reason why it is wrong to dispose batteries
everywhere.
Amniocentesis or Amniotic Fluid Test or Amnio is the process to examine genetic defects, fluid infection or sex determination by inserting a needle into the Amniotic fluid surrounding the unborn fetus.
<u>Explanation:</u>
<u>Amniocentesis</u>
Amniocentesis is a prenatal diagnosis which is used to determine genetic defects, fluid infection or sex determination by inserting a needle to draw a small sample of fetal cells through the amniotic fluid surrounding the unborn fetus.
The prime aim of Amniocentesis is to detect chromosomal deficiencies and cure the fetus with all possible processes so that the baby may be normal and healthy at the time of delivery.
This process is performed when the woman is 15-20 weeks pregnant. The test has the tendency to spread quick and possesses the probabilities of miscarriage.
I think all the mice had brown fur due to epistasis
Explanation:
The expected results would be 50% black and 50% brown and the ratio could be 2:2. But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.
