Questions:
1.
The Kermode (Spirit) bear sub-population of black bears is estimated to include ~1300
individuals that reside along the western coast of British Columbia, Canada.
Approximately 20 percent of the bears on Princess Royal & Gribbell Islands are white;
the rest are black. Assuming complete dominance of the black coat color, calculate the
expected genotype frequencies, where
B
= black coat color, and
b
= white coat color.
3
points for each
genotype frequency
2.
Based on the genotype frequencies above, what is the allele frequency of the white (
b
)
allele?
Worth 3 points

Assignment SummaryIn this assignment, you will think of scientific questions that will help you better understand the role ofDNA and chromosomes in the expression of heritable traits in an organism. You will then conductresearch to answer these questions. Finally, you will compose a typewritten document that states yourquestions and provides your answers.Background InformationDNA in the nucleus of a cell contains the genetic code that dictates the structure and function oforganisms. DNA is compressed into structures called chromosomes. Chromosomes are made ofsegments of DNA called genes. Genes are the basic units of heredity in organisms and are transferredfrom parent to offspring.DNA contains the genetic code, or the set of instructions, in the form of triplet codons, for assemblingamino acids into proteins. All organisms share a similar genetic code based on the same DNA codons.The order of the codons differs, allowing for diversity among organisms.Not all DNA codes for proteins.…

Background:
Animals are multicellular eukaryotes from the kingdom Animalia.
This kingdom is vastly diverse. It contains organisms as massive as
So-foot-long bluc whales to microscopic organisms such as rotifers
and dust mites that can only be seen with powerful microscopes.

Morphological analogs are structures having similar functions but different origins. For
example, the wing of an airplane and the wing of a bird are analogous but certainly have
different origins. Name and explain the comparisons of THREE ideas that humans have
borrowed from plants and animals to use in building structures and making materials.

A student in a course on intelligent design theory claims that the graph in part (a) shows that losing the ability to respire actually is adaptive for yeast cells living in small populations. Please read the incomplete sentence that appears immediately below, assess as possible completions the lowercase-Roman-numeral-labelled statements that follow, and click each uppercase-letter-labelled response that is presented below and completes accurately the sentence.
An astute student in an evolution course would respond that
i. the graph in part (a) shows that selection among mitochondria within yeast cells can lead to fixation for traits that decrease mean fitness for that yeast population.
ii. the student in the course on intelligent design is wrong; the yeast cells in the small population group retained completely the ability to respire, as they otherwise would have…

concept map" connecting the BIO 001 Lecture Topics to Biology Core Concepts.
a. In the box provided below, connect the BIO 001 Lecture Topics listed below. Draw
boxes around each topic and lines to connect the topics to each other. Draw as many
lines as you see fit.
b. On each line, write an action word or phrase that describes how the topics are
connected (e.g., energy might be connected to grow by the phrase "organisms need
energy to grow").

please write your response to 1 of the options below. Ensure you include specific details of your ideas. Also, explain WHY you have chosen to highlight those aspects and make connections between the materials and your own previous knowledge and/or lived experiences.
#1: Science is not done in a vacuum by singular hero-scientists -- it is a team effort. Which of these other scientists (i.e., not Darwin) highlighted in the lecture OR on the Evolutionary Scientists Today, Bio Anth Edition page did you find most surprising or intriguing? Why?
#2: Evolution is not a mystery. We have observed many examples of populations changing over time both in the lab and in the wild. Which of these examples of Natural Selection in Action helped you understand how natural selection works the most? Why?

Question: Why pseudoallelism occuring in organisms?
arrow_forward
Hello, I need help answering 5c & 5d using the phylogeny below(letter (A) graph to the left). Pls and thank you!
a) In the 1990s, when only mitochondrial DNA sequencing was available, geneticists claimed that there was no hybridization between humans (Homo sapiens) and Neanderthals (Homo neanderthalensis). Does the phylogeny shown above support the claim humans did not hybridize with Neanderthals in the past? How can you tell?
b) Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why?
c) Did female H. sapiens hybridize with Neanderthal males to produce fertile offspring that then back-crossed with modern humans? What does the graph say about this?
d) Did male H. sapiens hybridize with Neanderthal females that then back-crossed with modern humans? What does the graph say about this?…
