He first step in solving this problem requires an examination of the possible genotypes of the parents. As stated color-blindness is a recessive linked trait. So the genotypes of the parents should be:
<span>mother's genotype (normal vision but whose father was color blind) XNXn</span>
She is a carrier because of her heterozygous condition. For the recessive gene to be expressed one must be homozygous for it.
<span>father's genotype (color blind) XnY</span>
<span>

The advantage i see in light microscope when compared to electron is the fact that we can view cells while they are alive and the fact that we have wider range of differential stainings for all types of cells.
In electron microscope the tissue has to be extremely thin and fixed, meaning, dead. So we cant see them like, 'while' they are dividing, we can just catch the fixed state of division. And stains have issue, its harder to deal with stains in electron microscope because of its properties in reflecting them.
These are the ones I saw as important while working in labs.
Explanation:
Food and liquids are processed by the digestive system. After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body.
A <u>pathogen</u> is made up of nonliving pieces of DNA or RNA wrapped in a protein shell.
Hi There!!
I believe the answer you are looking for is vegetation. Coastline similarities, fossils and rock patterns all support the theory of plate tectonics.
I hope this helps:)
