Document Summary

Frequency: how many times an allele occurs within a population. Complete dominant: both bb and bb appear the same (have the same phenotype) Incomplete dominance: bb will have different phenotype than bb. 2pq= frequency of bb q2= frequency of bb. Decide what to investigate using set protocol and write up journal style report. A fungus is a kingdom in the eukarya domain which has cell walls, are absorptive heterotrophs. Symbiosis: when two organisms have a relationship which can be parasitic, cause benefit for one party, or benefit for both parties. Endophytes: microbes living inside plants that colonize living, internal tissues of plants without causing any immediate, overt negative effects. Plants benefit from: pathogen inhibition, herbivore resistance, increased environmental tolerance, anti- insect, increased growth.

A rare disorder of cystic fibrosis (characterized by abnormal transport ofchloride and sodium across an epithelium, leading to thick, viscous secretions) occurs every 1 in 3,300 births. To express this trait one must be homozygous recessive (ff).

The cystic fibrosis allele is represented by f. The normal allele is F. Suppose both parents have alleles Ff. The possible combinations of alleles in the children are FF, Ff, Ff and ff. The alleles ff will cause the disease. So, although the parents do not have cystic fibrosis, they can produce children with the disease. The parents are called 'carriers' of the disease

What is the frequency of the population that carries the trait? (Ff)

a) mitosis b) decrease c) Heterozygous recessive d) increase e) dominant f) homozygous dominant g) out- breading h) plant poination by bees i) heterozygous j) migration k)recessive l) large population m) evoltion n) meiosis o) founder effect

You are an ecologist studying a population ofgerbils that can be found in nature with 3 different colors. Anindividual gerbil can be, dark brown, medium brown, or lightbrown. There are 2 alleles for this gene B and b. Thecolor trait is determined by incomplete dominance. This is a casewhere one allele is not dominant over the other but insteadheterozygous individuals show an intermediate phenotype. In thiscase of incomplete dominance Dark brown individuals are homozygousBB, medium brown individuals are heterozygous Bb, and light brownindividuals are homozygous bb. You spend a night trapping andcatch.

10 Dark brown gerbils
10 Medium brown gerbils
10 Light brown gerbils

What is the gene pool in thispopulation?
What is the gene frequency in thispopulation?

Explain how genetic drift could alter thegene frequency in a population. Use your data from the geneticdrift experiment to support your answer.
