Dafna11 [192]

Creationists criticize the idea of natural selection as a circular argument, or tautology, claiming "the fittest are those that survive, and survival is how fitness is defined. "

The definition of natural selection is not tautological because natural selection is measured by contribution to the next generation, not simply survival of an individual organism.

Tautologies or circular arguments are true at all times and therefore are not productive as theories since they cannot be disproved. A tautology is a statement which is true by necessity.

Natural selection is the prevalent theory which explains biological change by predicting the mechanism behind evolution.

Nevertheless, natural selection can be explained non-tautologically. It should be described as the theory which tries to speculate as well as retrodict evolutionary change by environmental forces affecting the organisms.

E is a dominant allele for wet earwax and e is a recessive allele for dry earwax. if two individuals with the phenotype of wet e
MrRissso [65]
Given 
E dominant allele for wet
e recessive allele for dry

that means
for phenotype wet, the possible genotypes are EE, or Ee, and
for phenotype dry, the only possible genotype is ee.

Therefore we also know that the child who has dry earwax has genotype ee.
Since the child inherits one allele from each parent, therefore each parent must have a recessive allele "e".

If both parents have phenotype wet earwax, they both must be heterozygous for wet/dry earwax, namely Ee.

Which best describes meiosis?
Mariulka [41]

The right answer is It produces male and female sex cells.

Meiosis is the process of double cell division allowing the formation of gametes, or sexual cells in eukaryotic organisms. It differs from mitosis, somatic cell division, which takes place only in a time. From a diploid mother cell, we obtain four haploid daughter cells with different genetic material.
