What is the difference between phreatomagmatic eruption to phreatic eruption??

1 answer:

5 0

Phreatomagmatic eruptions are volcanic eruptions resulting from interaction between magma and water while phreatic eruption is a steam eruption without lava ejection.The eruptions are caused by groundwater flashing to steam as it is heated by magma.

pThe probability of having an offspring with both the dominant phenotypes for both genes is equal to the product of the individu

Elena-2011 [213]

The product probability rule states P(A∩B) = P(A) x P(B). In the exposed example, the probability of having a dominant phenotype is 9/16.

<h3>What is the product probability rule?</h3>

The product probability rule allows us to calculate the probability of occurrence of event A and event B at the same time.

It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.

This rule is based on the dependence or independence of the events. If two events A and B are independent of each other, the occurrence of one of them does not affect the occurrence of the other one.

For independent events, the rule establishes that, given two different events A and B, the probability of occurrence of both together is

P(A∩B) = P(A) x P(B)

The probability of inheriting one of the alleles from each parent is 0.5 (beacause each parent has two alleles).

According to this, the probability of having a dominant phenotype for both traits depends on the paretal genotypes.

For instance, let us analyze the cross between two dihybrid individuals AaBb x AaBb.

Assuming the involved genes code for different traits and both are independent genes, for easier calculations, we can perform crosses that involve each of the genes separately -events-, and then multiply de results according to the genotype and phenotype we are interested in (A-B-)

Gene A

Parentals) Aa x Aa

Gametes) A a A a

Punnett square) A(1/2) a(1/2)

A(1/2) AA(1/4) Aa(1/4)

a(1/2) Aa(1/4) aa(1/4)

F1) Genotype

1/4 AA ⇒ 1/2A x 1/2A

2/4 = 1/2 Aa ⇒ (1/2A x 1/2a) + (1/2A x 1/2a)

1/4 aa ⇒ 1/2a x 1/2a

Phenotype

3/4 A- ⇒ 1/4AA + 2/4Aa

1/2 aa

Gene B

Parentals) Bb x Bb

Gametes) B b B b

Punnett square) B b

B BB Bb

b Bb bb

F1 Genotype

1/4 BB ⇒ 1/2B x 1/2B

2/4 = 1/2 Bb ⇒ (1/2B x 1/2b) + (1/2B x 1/2b)

1/4 bb ⇒ 1/2b x 1/2b

Phenotype

3/4 B- ⇒ 1/4 BB + 2/4 Bb

1/2 bb

The probability of having a dominant genotype and phenotype for both traits is,

Genotpe AABB ⇒ 1/4 AA x 1/4 BB = 1/16 AABB

Phenotype A-B- ⇒ 3/4 A- x 3/4 B- = 9/16 A-B-

Consider a mutation in which the change is from uac to uau. Both codons specify the amino acid tyrosine. Which type of point mut

ddd [48]

The correct answer is: silent mutation

There are a few types of genetic mutation that can change genetic code. Those mutations can be classified:

1. Substitution-only one base is changed

• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon

• Missense mutations-when one nucleotide is substituted and a different codon is formed

• Silent mutations-when a nucleotide is substituted and the same amino acid is produced

2. Insertion- extra base pairs are inserted

3. Deletion- section of DNA is deleted
