Question
Chapter 13, Problem 12TYK
Summary Introduction
To review:
The mechanism that is responsible for causing variation in chromosome number among the mammals.
Introduction:
Cell division results in the formation of two or multiple daughter cells from a parent. A cell might undergo either mitosis and meiosis, in order to divide itself, however, each one is specific for different types of cell. These divisions lead to the formation of gametes.

Biology
A colleague has given you a population of avian neural crest cells to use in an in vitro culture system, but that individual keeps poor records and does not remember if the neural crest cells are still undifferentiated. How would you go about testing the cells to determine if they were undifferentiated or differentiated down a particular neural crest lineage? Include your experimental design and any necessary controls you will need to interpret your results.
Describe the evolution of primate chromosomes.

Why do you think they prefer to use fruit flies instead of elephants?arrow_forwardin a summary use your understanding of molecular biology to explain that recessive alleles are expressed through transcription and translation, and that they may have functional gene products. Describe how the interaction of the products produced by each allele results in what we see as dominant or recessive traits.arrow_forward

Briefly explain your choice.arrow_forwardUse the information and diagram to answer the following question. In humans, the pelvis and femur are involved in walking. Despite the fact modern whales live in water, they contain a pelvis and femur that are common in land dwelling animals. Based on your observation of the whale diagram and your understanding of evidence that supports evolution, what is TRUE about the pelvis and femur found in living whales today? A. They are newly developed structures found in modern whales due to mutations. B. They are examples of fossilized remains of ancient organisms. C. They are traits acquired by modern whales over time as they adapted to living in water. D. They are vestigial structures which are remnants of structures that served a function in the organism’s ancestors.arrow_forwardOn an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here? Group of answer choices development high complexity evolution requirement for resources irritabilityarrow_forward
