Question
Chapter 24, Problem 1QC
Summary Introduction
To explain:
Whether humans are evolved from chimpanzees or not.
Introduction:
Evolution is a term that can be defined as the changes in the biological or heritable characteristics in a species of a population over several generations.
Expert Solution & Answer
Explanation of Solution
No, the humans have not evolved from chimpanzees. Humans are the modern species which share a common ancestor with the chimpanzees. Homo sapiens show a close relation with the modern apes like African chimpanzees, and gorilla, but they did not evolve from the apes.
Both of these species that are humans and apes are turned into two lineages and the changes have occurred in both the lineages from generations to generations. One lineage turned into apes and the other is evolved into early humans.
Conclusion
Humans did not show any evolutionary relationship with chimpanzees. So, they did not evolve from the apes like chimpanzees. However, they just share the common ancestral relations with each other.

The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows:
aabb: yellow
AABB, AABb, AaBb, and AaBB: red
AAbb and Aabb: orange
aaBB: yellow
aaBb: ?
Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?
Question 21 options:
orange because A is epistatic to B
yellow because A is epistatic to B
red because B is epistatic to A
orange because B is epistatic to A
red because A is epistatic to B
yellow because B is epistatic to A
A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation?
The cell membranes are more resistant than normal.
An isotonic solution had been added instead of water.
A solution of 0.1 M NaCl had been added instead of water.
Not enough water had been added to the red blood cell pellet.
The man had sickle-cell anaemia.

It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forward

So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants. Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus.
