Genetics - Human Blood Types

Part 1: Genetics Problem- Human Blood Types Mendel is the father of modern genetics, but there are some genetic characteristics that cannot be explained by simple Mendelian genetics. Such is the case with the human blood types in which there are 3 alleles for the same gene, A B, and o. A parent can pass allele A, B, or o to the offspring based on the parent’s genotype. From these 3 alleles, there are 4 blood types (phenotypes): A, B, AB, and O, and there are six genotypes: AA, Ao, BB, Bo, AB, or oo. This is an example of codominance in which both A and B alleles are codominant to each other. Blood types can be used in forensics to determine if blood is from the victim or criminal... click for more

A study of energy flow in a Georgia salt marsh revealed that gross production was about 36,380 kcal/square meter/year

A study of energy flow in a Georgia salt marsh revealed that gross production was about 36,380 kcal/square meter/year of which 7,900 kcal/square meter/year formed detritus and 305 kcal/square meter/year was consumed by insects. a. What proportion of gross production was used for respiration? Show calculations b. What proportion of net production went directly to consumers? Show calculations

Nitrogen Cycling

Assume that nitrogen cycling in a deciduous forest ecosystem is complete and involves all the producers, consumers and nitrogen fixing, denitrifying and ammonifying bacteria described in lecture a. Trace an atom of N (N15) that was released into the atmosphere of the forest through its route to a bacterial cell that releases it back to the air. b.Suppose that decompsers were removed from the forest ecosystem, predict what would happen to the rate of nitrogen cycling. Explain the logic behind your prediction.

Interpreting data; Chi-square test

Please see the attached file. a. If students transplanted the germinated seeds on each day that they observed them, how many germinated seeds (seedlings) from the Plant Food treatment did the students transplant on Day 14? b. Of the seeds that were stratified in Water Only , the highest number of seeds germinated between days _______________ and _______________. c. Calculate the X^2 (chi squared) for Water Only versus Plant Food treatment on day 28. Show calculation.
