miv72 [106K]

(C) its genetic diversity is very low.

<h3>What is meaning of Extinction?</h3>

Extinction is the final phase of a sort of creature or a taxon—typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is typically considered to be the moment of extinction.

Determining this point is challenging because a species' potential range may be quite wide, and is typically done after the fact. Due to this problem, there are phenomena like Lazarus taxa, in which a species that was thought to be extinct suddenly "reappears" after a period of apparent absence (usually in the fossil record). Estimates place the number of extinct species at over five billion, or more than 99% of all species that have ever existed on Earth.

Alkaptonuria is an infrequent autosomal recessive condition. It is first noticed in newborns when the urine in their diapers tur
Arisa [49]

Answer:

See the answer below

Explanation:

Let the disorder be represented by the allele a.

Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.

Since the four adults are carriers, their genotypes would be Aa.

                    Aa     x     Aa

Progeny:    AA    2Aa    aa

Probability of being affected = 1/4

Probability of being a carrier = 1/2

Probability of not being affected = 3/4

(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2

(b) The chance that  the third child of Sara and James will be free of the condition = 3/4

(c)

(d) If someone has no family history of the disorder, their genotype would be AA.

                 AA     x     aa

                        4 Aa

<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0

(e)

(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0
