A certain area received a large amount of rain and some of it remained on top of the soil. What happened to the rest of this wat
ValentinkaMS [17]

In the large rainfall is some water remains in the top of the soil the rest of this water is seeped into the ground.

<u>Explanation:</u>

  • Mainly the absorption of water by the ground depends upon the nature and the fertility of the soil.  
  • When the ground receives the water it mainly accounts for the absorption and then there will be a runoff. The absorption helps to raise the level of groundwater for future usage.
  • The amount of water that can get into the soil mainly depends upon the permeability of the soil surface. The water which can't infiltrate in the soil runs off into the water bodies.  
  • The water is an essential requirement for survival and the existence of biological organisms.

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
