In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made between true-breeding flies with curved wings and gray bodies to flies with true-breeding straight wings and ebony bodies. The F1 offspring were then mated to flies with curved wings and ebony bodies to produce an F2 generation. 1. Diagram the genotypes of this cross, starting with the parental generation and ending with the F2 generation.
2. What are the predicted phenotypic ratios of this F2 generation?
3. Suppose the following data were obtained for this F2 generation:
114 curved wings, ebony body
105 curved wings, gray body
111 straight wings, gray body
114 straight wings, ebony body
Conduct a chi-square analysis to determine if the experimental data are consistent with the expected outcome based on Mendel's laws.

Population of F2 generation will be formed on 9:3:3:1 ratio.

Explanation:

The predicted phenotypic ratios of F2 generation is 9:3:3:1. Ratio 9 represents straight wings, gray body which are dominant allele, ratio 3 represents hybrid flies having curved wings, gray body, ratio 3 represents hybrid flies having curved wings, ebony body and ratio 1 indicates flies with curved wings, ebony body. The population of F2 generation will be formed on the above ratio.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
