<h2>Answer:</h2>

This can be explained with an example.

Let’s lake an example of two species 1 and 2.

Species 1 has a wide genetic diversity due to which organism are also diverse in phenotype. Their phenotype are:  

Black, dark brown, brown, dark red, red, light red, pink, skin color.

From left to right organism are becoming less adapted to high temperature relatively.

For species 2:  This species has less genetic diversity and its phenotypic diversity is as follow:

Black, red, Skin color.

From left to right organism are becoming less adapted to high temperature relatively.

Now if there is the sudden high temperature in the environment; 4 Types of phenotype will survive are black, dark brown, brown, dark red.

While there will only two types of organism in specie 2 which will survive are black, red.

So that’s how the diversity of organisms increase the chances that some will survive a major change in environment.

Viefleur [7K]

Answer:

The elephant and the sheep exhibit higher sequence similarity because they are more closely phylogenetically related

Explanation:

The elephant and the sheep are mammals, while the crocodile is a reptile, being the mammals the most inclusive group among these three species and it appeared later in evolution. Mammals are organisms that have shared evolutionary features such as warm blood, they produce milk and have hair

Each of the four pedigrees that follow represents a human family within which a genetic disease is segregating. Affected individ
Ne4ueva [31]

 Answer:

<u> The following four traits are -: </u>

  • <u>Pedigree 1 -</u> A recessive trait (autosomal recessive)  is expressed by pedigree 1.
  • <u>Pedigree 2- Recessive inheritance is defined by Pedigree 2. </u>
  • <u>Pedigree 3</u> - The inheritance of the dominant trait (autosomal dominant) is illustrated by Pedigree 3.
  • <u>Pedigree 4-</u> An X-like dominant trait is expressed by Pedigree 4.    

Explanation:

<u>Explaination of each pedigree chart</u>-

  • Pedigree 1 demonstrates the <u>recessive trait </u>since their children have been affected by two unaffected individuals. If the characteristics were X-linked, in order to have an affected daughter, I-1 would have to be affected. X^A In this, both parents are autosomal recessive trait carriers, so the child will be affected by a 1/4 (aa)
  • <u> Recessive inheritance</u> is defined by <u>Pedigree 2</u>. This is<u> X-related inheritance as autosomal recessive</u> inheritance has already been accounted for in part 1. This inference is confirmed by evidence showing that the father (I-1) is unaffected and that only the sons exhibit the characteristic in generation II, suggesting that the mother must be the carrier. The individual I-2 is a carrier for this X-linked trait. A typical  Xa chromosome is attached to the unaffected father (I-1), so the chance of carrier II-5 is 1/2. Probability of an affected son = 1/2 (probability II-5 is a carrier) x 1/2 (probability II -5 contributes (X^A) x 1/2 (probability of Y from father II-6) = 1/8. An affected daughter's likelihood is 0 because a typical X^A must be contributed by II-6.
  • The inheritance of the<u> dominant trait</u> is demonstrated by <u>Pedigree 3 </u>because affected children still have affected parents (remember that all four diseases are rare). The trait must be <u>autosomal dominant</u> because it is passed down to the son by the affected father. There is a 1/2 risk that the heterozygous mother (II-5) would pass on mutant alleles to a child of either sex for an autosomal dominant feature.
  • <u>Pedigree 4</u> is an <u>X-linked dominant function</u> characterized by the transmission to all of his daughters from the affected father but none of his son. On the mutant X chromosome, the father (I-1) passes on to all his daughters and none of his sons. As seen by his normal phenotype, II-6 therefore does not bear the mutation. An affected child's likelihood is 0.    

In the question the pedigree chart was missing ,hence it is given below.
