Which of the following native Kentucky animals would most likely exhibit "K" selection? A) Black Bear B) Snapping Turtle Spotted Bass Monarch Butterfly

A recent outbreak of ranavirus in salmon has you concerned.  During your fieldwork you’ve discovered that individuals that have a hard operculum (gill covering) survive best because the virus cannot gain access to the gills.  Individuals with a soft operculum suffer 64% mortality due to ranavirus infection.  The hard operculum is a dominant trait.  You surveyed your population and found AA: 36, Aa: 45, and aa: 21. Showing the math increases the possibility of partial credit. Clearly indicate in your answer: The allele frequencies (both p and q) of your current population The allele frequencies (both p and q) you expect in the next generation due to the ranavirus outbreak

Which of the following traits is more associated with an Opportunistic (Equilibrial) species?  Which of the following traits is more associated with an Opportunistic (Equilibrial) species?   A. Short maturation time   B. Producing offspring at many different times over the course of life   C. Producing a lot of eggs at one time   D. High juvenile mortality   E. High level of parental care

Imagine three islands, each with a population of frogs. There are approximately 1,100 frogs on Island 1, 400 on Island 2, and 400 on Island 3. Researchers estimate that these populations have been separated for 800 years. Individuals in these populations show variation in markings on their body by shape and color. Frogs on Islands 1 and 2 have circle markings that are either red, blue, or purple. All frogs on Island 3 have yellow triangle markings.  The islands recently became a tourist destination, with new passenger boats connecting Island 1 and Island 2, and Island 1 and Island 3 (there is no boat that goes between Island 2 and Island 3).   Would a biologist agree or disagree with the following statements?  part 1:  It is possible that yellow or triangle markings exists on Island 1 at some point in the past. Question options:   Agree   Disagree part 2:  Genetic drift is not occurring on Island 1.   Question options:…

In Procedure 9.1, we will model natural selection in a prey population. Our prey population is beans. The students are the predators. As predators, you are going to capture the biggest beans possible. Whichy size prey will survive the hunt, the large ones or the hsmall ones?

In lizard species "A" the males approach the females directly, bobbing their whole body up and down and displaying their bright blue belly patches as they do so. In lizard species "B", the males slither around the female and bob only their heads. They have no belly patches at all. The females of each species will reject the males of the other species because of these differences. This is an example of isolation. habitat and post-zygotic habitat and pre-zygotic mechanical and post-zygotic behavioral and post-zygotic isolation behavioral and pre-zygotic mechanical and pre-zygotic

What affect will inbreeding tend to have on genotypic frequencies in a population? a) It will increase the frequency of genotypes that produce a dominant phenotype. b) It will decrease the frequency of genotypes that produce a dominant phenotype. c) It will increase the frequency of homozygous genotypes. d) It will increase the frequency of heterozygous genotypes.

Species A experiences a mutation that produces a favorable allele to avoid predation by species B. In turn, species B experiences a mutation that helps it to counter the 'predator avoidance' allele that appeared in species A. What term best describes this situation?

Generally speaking, natural selection tends to select for dominant alleles while genetic drift tends to favor recessive alleles. 1)True 2)False

Icefishes live in the Southern Ocean, which encircles Antarctica. Icefishes have evolved to produce antifreeze proteins which prevent ice crystals from forming in their blood, when ocean temperatures drop below the freezing point of fresh water.  The antifreeze proteins, which are produced in different amounts (high, medium and low) in different fishes, help them live in the cold waters.   What are the different variations of the antifreeze protein present in the population of icefish?           2. Out of the variations which one is the favorable trait in the environment of the icefish?       3. Which icefishes will natural selection select for?       4. How will the icefish population in very cold waters, change over time?           5. Describe the adaptation in icefish (in terms of allele frequency and reproductive fitness)
