lisov135 [29]3 years ago
5 0

Answer:

Municipal of sewage in water ​

Explanation:

The municipal sewage water ​has a large number of microbes present in it that leads to lower level of oxygen in water. The reduction of oxygen in water occurs due to decomposition of algae present in water by microbes. Algae is responsible for the production of oxygen from the process of photosynthesis. When they are removed from an environment then no more oxygen will be produced which leads to decrease of oxygen in water.

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
