Below are the 3 requirements for natural selection to happen. Selection cannot happen unless ALL 3 requirements are met. After each dash, say why selection would NOT occur without this requirement Variation – Heritability – Different fitness for each variant – How is it possible for selection to NOT […]

Sulfur Part 2: Two exceptions (see question above) include (Circle exactly two) * A. Phenylalanine B. Leucine C. Tryptophan D. Proline e. Methionine […]
1.) A large population of land turtles on an isolated island has…
1.) A large population of land turtles on an isolated island has two alleles for a gene that determines shell thickness. The allele for thinner shells is dominant over the allele for thicker shells. The thinner-shell allele occurs at a frequency of 80%. Assuming there is no net advantage to thick or thin shells, what […]

DIHYBRID CROSSES PRACTICE PROBLEMS Your Task To familiarize yourself with Dihybrid Crosses, please complete the practice problems in this document. Set up a Dihybrid Cross using the following information: Dominant allele for tall plants = T Recessive allele for short plants = t Dominant allele for purple flowers = W Recessive allele for […]

A) B) 1. Select the option that BEST describes the relative fitness of organisms. Group of answer choices The probability of a population killing or eating another population before being eaten by a predator. The genetic contribution of a phenotype relative to all other phenotypes in the same population. How well people survive and reproduce in an environment. […]

1.) Imagine a species whose eye color is determined by a receptor molecule called eyeC. When eyeC is not activated, cAMP levels in the cell are low and blue pigment is produced. When eyeC is activated by the binding of the signal molecule, cAMP levels rise and yellow pigment is produced. The P allele […]

Which statement below about nucleotides is TRUE? A.) Base pairing occurs between adjacent nucleotides within a single strand of DNA B.) A nucleotide is a polymer, for which the monomers are molecules of DNAC.) In a nucleotide, the sugar is either deoxyribose (in DNA) or ribose (in RNA) D.) A nucleotide is composed of two […]

1. According to the competitive exclusion principle, two species cannot exist together if they occupy the same niche. Either they diverge their niches so they can coexist or one species will die out. All of the following are consistent with the principle of competitive exclusion EXCEPT a.Two species that share the same niche will exclude […]

Silent mutations are the most common type of mutation. Search for a silent mutation in any organism. What is the mutation (on a molecular level)? What gene is the mutation on? What makes it silent? Do you think this has the potential to become nonsynonymous (do not answer generically with ‘if the environment changes or […]
