Answer:

The finch population decreased.

Explanation:

When finches eat seeds, some pieces fall onto the ground which grow up to have more seeds. The seeds that survived were too big for a finches tiny beak. Without this cycle in place, seeds had no way to reproduce.

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

MrRissso [65]

As food becomes scarce, monkeys within the same tribe can fight for food resources. This behaviour describes intraspecific competition.

<h3>What is intraspecific interactions?</h3>

Intraspecific competition is a competition between someone from the same species . Theimpact of competition on each individual within the species relies on the type of competition that takes place.

'The competition' may be inactive or active and may result in ovarious outcomes.
