Explanation:

When performing a hair DNA test for the purpose of paternity, it is a must to have a complete hair sample – with hair shaft and hair follicle. On the other hand, if the purpose of hair DNA testing is for forensic use, a cut hair sample even with no follicle can still be of use. However, a complex procedure has to be made.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
