Molodets [167]

Answer:

The correct answer is DNA or RNA. Viral chromosomes exist in a variety of conformations and can be made up of <u>DNA or RNA</u>

Explanation:

The hereditary material of viruses is organized into chromosomes of different types. From the genetic point of view, viruses can be classified into DNA or RNA viruses, double helix or single helix, and circular or linear, that is, viral chromosomes are linear or circular molecules of DNA or RNA. Viruses can be classified according to the type of organism they parasitize in: Bacteriophages or phages, animal viruses and plant-type viruses. Viral chromosomes are also subject to the recombination process, this happens when an individual cell is infected simultaneously by two mutant strains of a virus.

If you know that a population is 75% the dominant phenotype and 25% is the recessive phenotype, can you determine approximately
Andreyy89
If dominant allele = p, and recessive allele = q,
and p+q = 1, then:
{(p + q)}^{2}  =  {p}^{2}  + 2pq +  {q}^{2}  \\ where \:  {p}^{2}  \: is \: homozygous \: domin \\  {q}^{2}  \: is \: homozygous \: recessive \\ and \: 2pq = heterozygous
So if 75% have the p, then p^2 = homozygous dominant
{p}^{2}  =  {(.75)}^{2}  = .5625
And if the other 25% have the q, the q^2 = homozygous recessive
{q}^{2}  =  {(.25)}^{2}  = .0625
Now those remaining MUST be the heterozygous, thus 2pq are those:
2pq = 2(.75)(.25) = .375

Therefore homozygous dominant are 56.3% and heterozygous are 37.5%

How do scientist use probability in genes
Harlamova29_29 [7]
I think I know but it should be (below)

One probability rule that's very useful in genetics is the product rule, which states that the probability of two (or more) independent events occurring together can be calculated by multiplying the individual probabilities of the events. ... For instance, consider a cross between two heterozygous (Aa) individuals.
