Biology Questions

Unlike Mitosis, Meiosis results in the formation of 4 Genetically different cells.

Meiosis results in the formation of 4 Haploid daughter cells from one Diploid parent cell.

The branch of biology that studies the different structures and functions of the cell is called Cell Biology or Cytology.

 A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life"

Cell Biology deals with :

• Life cycle 

• Structure and organisation of cell organelles and their physiological properties. 

• Metabolic processes 

• Interactions with their environment 

• Signalling pathways.

Mutations are accidents in the copying of DNA. A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. 

Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo. These changes if they are in the germ cell will be passed on to other organisms formed by sexual reproduction or asexual reproduction. An example would be the golden delicious apple. A lost of genetic information due to a mutation resulted in a different color of fruit.

Genetic mutations that cause diseases are not always passed on to offspring. 

August Weismann cut off the tails of mice for 21 successive generations and still they produced generation after generation of only tailed young ones. So he concluded that acquired characters are not inherited.
