B. Mutations cause a person's body cells to divide uncontrollably. There isn't a signal for cells to stop dividing, so this can cause cancer because cancer cells won't stop dividing without this signal.

Ede4ka [16]

Complete question:

Thinking creatively about evolutionary mechanisms, identify at least

two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.

<u>Select the two correct answers.</u>

-inbreeding among individuals in the population

-purifying selection against mutational variants of alleles in the population

-continuous migration of individuals with new alleles into the population

-mutations that do not severely affect viability and reproductivity

-genetic drift of alleles common in the population

-events leading to genetic bottleneck effect

Answer:

The two events that might favor heterozygotes among the options are  

  • The Continuous migration of individuals with new alleles into the population
  • Mutations that do not severely affect viability and reproductivity.  These might favor heterozygous frequencies.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

svet-max [94.6K]
The question is the following :
<span>What is the best evidence to prove that Irene was heterozygous for hemophilia?
A) Alice carried the recessive allele.
B) Alexandra carried the recessive allele.
C) Frederick carried the recessive allele.
D) Waldemar carried the recessive allele.


The correct answer is A

In the pedigree, marked with blue are the carriers of the X recessive allele ( they have one X that has the mutation and the other that doesn't).
Alice was Irene's' mother, and since both Alice and iIrene have the allele, it is safe to conclude that Irene inherited the recessive allele from Alice.</span>

Stella [2.4K]

Answer:

A key feature of animal body plans is that they can show multiple types of symmetry.For example,,a dog would represent bilateral symmetry,while a jellyfish and other cnidarians would represent <u><em>radial symmetry</em></u>.

Explanation:

In biology, symmetry can be described as the balanced distribution of the body shape of an organism.

Radial symmetry can be described as a symmetry which depends on a central axis. The symmetry of cnidarians depends on a central axis hence they have radial symmetry.

Bilateral symmetry can be described as a symmetry in which the two halves of the symmetry are mirror images of one another. For example, humans, dogs etc.
