A person’s hands are exposed to sunrays every day and gradually it leads to the accumulation of mutations in its skin cells. This, in turn, leads to skin cancer in that area. Determine if these mutations will be passed on to the offspring. Give specific reason for your answer and also state the type of mutations that can be inherited and the ones that cannot be inherited.

People with sickle-cell trait are _________________(heterozygous/homozygous) for the sickle-cell allele.

Hydrolytic enzymes are the enzymes that breakdown unwanted components inside the cell. They must be segregated and packaged to prevent general destruction of cellular components. Which of the organelles contains these hydrolytic enzymes in animal cells? 

The Out of the three types of RNA, it is __________ that actually has the code to make proteins.

Because they only affect a single amino acid, missense mutations do not have a significant effect on protein function.

We get exposure to radiations all the time, UVB radiations, which are dangerous than UVA, damage the DNA by forming thymine dimers. However, our cells have the two types of DNA repair system in place called as __________________ and ________________.

____________ are the chemicals or radiations that delete, substitute or add bases. An organism maybe exposed to them intentionally, accidentally or naturally.

A species of mice can have gray or black fur and long or short tails. If gray is recessive and long is dominant, using the gene symbols G for black, g for gray, S for long and s for short, what would be the genotype of a black-furred, short-tailed mouse?  

If a couple have 10 boys, then the probability that they will get a girl as their 11th child is 50%.

The field of genetics that studies the relationship between chromosome variations and specific traits is called Mendelian genetics.
