Answer:

pyroclastic flow is a fast moving current of hot gas and volcanic matter that flows along the ground away from a volcano at high velocities.

Hotspot is volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle

caldera-a large volcanic crater, especially one formed by a major eruption leading to the collapse of the mouth of the volcano.

tephra-rock fragments and particles ejected by a volcanic eruption

epicenter-the central point of something, typically a difficult or unpleasant situation

fault-an extended break in a body of rock, marked by the relative displacement and discontinuity of strata on either side of a particular surface

Congenital analgesia is a rare autosomal recessive trait. What is the likelihood that the first two offspring of a cross between
telo118 [61]

The likelihood that the first two offspring of the cross will have congenital analgesia would be 1/16

<h2>Autosomal Recessive Traits</h2>

For autosomal recessive traits, two recessive alleles are needed for the trait to manifest while one recessive allele means heterozygosity.

In this case, let us assume that congenital analgesia is represented by the allele b; heterozygous individuals will, thus, be Bb.

            Bb    x    Bb

          BB   Bb   Bb   bb

Probability of producing unaffected offspring = 3/4

Probability of producing affected offspring = 1/4

Likelihood of the first two offspring having congenital analgesia = probability of first having congenital analgesia and the second having congenital analgesia

    = 1/4 x 1/4

        = 1/16
