Virus : <span>Any of various submicroscopic agents that infect living organisms, often causing disease, and that consist of a single or double strand of RNA or DNA surrounded by a protein coat. Unable to replicate without a host cell, </span>viruses<span> are typically not considered living organisms

Virion : T</span><span>he infectious particle that is designed for transmission of the nucleic acid genome among hosts or host cells. A </span>virion<span> is not the same as a virus. I </span>define<span> virus as a distinct </span>biological<span> entity with five different characteristics

</span>Viroid: An infectious agent that consists solely of a single strand of RNA and causes disease in certain plants. Viroids<span> lack the protein coat (known as a capsid) of viruses and are the smallest known infectious agents.</span>

B=black and b=brown. A Bb guinea pig crosses with a Bb guinea pig, and four offspring are produced. All of the offspring are bla
Sladkaya [172]

If two Bb guinea pigs cross, there are four possible outcomes:

  • both pass the B: the son is BB
  • one of the pass the B and the other pass the b: the son is Bb
  • both pass the b: the son is bb

Since B (being black) is dominant, the son will be black in both BB and Bb cases. In order for a son to be brown, he must be a pure bb specimen.

So, if all of the offspring are black, it means that all four guinea pigs are either BB or Bb, which in turn means that at least one of the parents passed the B gene.

A population of fruit flies where wing shape is determined by one pair
AVprozaik [17]

The value of 2pg in the given population is 0.432

<u>Explanation:</u>

Given:

C is normal

c is curly wings

So the homozygous dominant condition would be CC

Heterozygous condition would be Cc

Recessive condition would be cc

According to Hardy Weinberg principle,

p² + 2pq + q² = 1

and

p + q = 1

Here,

q² = cc = 100

q² = 100 / 1000

q = √0.1

q = 0.316

So,

p + q = 1

p + 0.316 = 1

p = 0.684

Thus, 2pq would be:

= 2 X (0.684) X (0.316)\\\\= 0.432

Therefore, the value of 2pg in the given population is 0.432
