Genetics test Week 31 Hardy Weinberg 1. If the frequency of allele p in a certain population is 0.78‚ what is the frequency of allele q? (1) 2. If the frequency of recessive homozygotes for a particular gene within a population is 0.36‚ what is the frequency of the recessive allele? (1) 3. What does the “2pq” part of the equation represent? (1) The peppered moth Biston betularia showed an increase in melanic (dark) forms during the industrial revolution. In most polluted

“To what extent does genetic inheritance influence behavior?” A debate of nature vs. nurture‚ as in whether it is our inherited genes or environmental factors that affect our behavior‚ has been going on for years. There are no true experiments on genetic inheritance influencing behavior due to ethical reasons. Only quasi-experiments and theories of pre-existing data are available that are on genetics or environmental factors affecting behavior. With the few studies existing one can still argue

The cause of albinism is a mutation in one of several genes. Each gene provides the chemical code instruction for making one of the several proteins involved in the production of melanin. Melanin is what makes the color of the skin its color and also your eyes and hair. You must inherit two copies of a mutated gene in order to have albinism. Albinism is not always apparent in a person’s skin‚ hair‚ or eye color. All albinism victims will experience vision impairments. You may have rapid‚ involuntary

What is a gene? A gene is a continuous DNA segment that is transcribed into a single preRNA molecule. A zoologist and geneticist named Thomas Hunt Morgan is known for his research with fruit fly. Thomas Morgan was born on September 15‚1866 in Lexington‚ Kentucky. In 1886‚ he received his B.S. degree at the University of Kentucky. In 1910‚ Morgan saw that one male fly had a distinct difference about it. Instead of normal red eyes‚ this fly had white eyes (Allen). He wanted to test the breeding of

11 Genetic and Environmental Influences on Human Development 11.1 Introduction We may often wonder about the reasons and forces which shape our personality and character. Each one of us has a specific kind of nature which takes that particuler form because of the effect of two major factors. The first is the genetic make-up which we inherit from our parents‚ and the second influence comes from the various experiences we have in our interaction with our surrounding environment. This includes

Drosophila melanogaster are a species more commonly known to us as fruit flies. They are extremely important in biological research due to the fact that they make excellent model organisms for understanding genetics. Reasons behind their frequent use include; easily cultured in the lab‚ short generation time‚ and they can produce many offspring. In this lab report‚ we began with three different strains of Drosophila. Introduction The common form of Drosophila is known as the “wild type”‚ any fly

1. REVIEW: Explain how each recent theoretical perspective regards children and adults as active contributors to their own development. (pp. 20–25) Each theoretical perspective regards children and adults as active contributors to their own development. Information Processing began with the idea that the human mind can act as a manipulating system through which information flows. It is a perspective that demonstrates people that learn from their thinking to solve a problem. It is suggested that

Question: If I cross a female apterous fly with a male wild fly‚ what would the offspring look like? Hypothesis: If I cross a female apterous fly with a male wild fly‚ then the offspring will be a 50% chance of a apterous fly or 50% chance of a wild fly. If I cross a female apterous fly with a male wild fly‚ then the offspring will be a 100% wild fly. Supporting Evidence for Hypothesis: Apterous flies have no wings‚ and are a recessive gene‚ while wild flies have wings and are a dominant gene
