Answer #1

THE FOUNDER EFFECT -

B) Occurs when a new isolated population is founded by a small number of individuals possessing limited genetic variation relative to the larger population from which they have migrated.

The founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. As a result of of the loss of genetic variation the new population may be distinctively different , both genotypically and phenotypically from the parent population.

Many genetic diesease are increased in prevalence in human population due in part to the founder effect.

An example of the founder effect is the higher incidence of fumarase deficiency in a population of members of a fundamentalist church.

    For this exercise we will be re-enacting founder effect on a population of hypothetical people. You can use red and white beans (or any other small household item that comes in two colors) to complete the exercise. The beans will represent genes and the different colors will represent different alleles (gene variants). Red beans will represent the dominant (R) allele for the trait, while white beans will represent the recessive (r) allele. Humans have two copies of each gene, so...

    need help with this .. From the pages 571-587 attached below. 1a) Suppose a population of guppies was infected with a parasite. In that population a mutation results in a parasite resistant genotype that spreads through the population through natural selection. A subsequent mutation in the parasite results in a genotype that is unaffected by the newly evolved resistant guppy genotype. What is the name of the hypothesis that explains this host parasite “arms race”.? 1b) What is this name...

    explaim the mechanisms amd toxological effects if type 1 diabetes in this article Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...

    10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
