Answer: Your answer is True.
Explanation:
Answer:
The correct answer is C) gene flow
Explanation:
The biological species concept defines what is a species. It says that a species is a group of individuals in a population that interbreed with each other. So there should be gene flow between the members of the population to come under species.
Appearance does not define that two individual are of same species because even different species can look same for example Western meadowlarks and eastern meadowlarks looks identical to each other but they do not interbreed so there is no gene flow between them so they are not same species.
Therefore the primary criteria for determining species boundaries is gene flow.
When the patient with emphysema was
selected lung values changed (from those of the normal patient) in the
spirogram are:
ERV, IRV, RV, FVC, FEV1, FEV1 %
<span>The reason behind the changes of these values are due to the loss or inability of electric recoil. A spirogram (graph
like structure obtained by the respiratory movements) is measured by
spirometer.</span>
The first statement above is an example of incomplete dominance. If
the calf has black and white spots then that’s an example of codominance.
Incomplete dominance is a form of transitional
inheritance in which one allele for an explicit trait is not entirely expressed
over its paired allele. This effects in a third phenotype in which the
expressed physical trait is a mixture of the phenotypes of both alleles.
Codominance<span> is a form of dominance by which the alleles of a gene
pair in a heterozygote are wholly expressed. This effects in offspring with a
phenotype that is neither dominant or recessive. A usual example showing this type of dominance is
the ABO blood group system.</span>
