Genetics and Evolution3.3

Genetics and Evolution solves four types of basic problems commonly taught in introductory genetics courses in high schools and colleges. This app was originally designed for the Duke University (and Coursera) Introduction to Genetics and Evolution course, but it is helpful for any students, teachers, or practitioners in genetics! Problems solved include:

* Genetic cross mapping -- accepts genotype counts for three genes from a "test cross", and uses the counts to infer the gametic phase, the recombination rate between the three genes, and the gene order.

* Breeder's equation heritability -- with any three of the following values, calculates the fourth: starting phenotype, selected phenotype, response phenotype, broad-sense heritability.

* Hardy-Weinberg -- accepts genotype counts for a single gene and outputs observed genotype frequencies, expected genotype frequencies, and the coefficient of inbreeding (F).

* Population Growth -- with any of the following 3 values, calculates the fourth: Initial Population, Final Population, Time in years, Growth Rate (or separate birth/death rates)

* Self Test quiz-- quiz yourself on some common basic genetic terms.

* Allele Freak: track and graph the fate of alleles over multiple generations based on relative fitness, genetic drift etc

* Cross Simulator: simulate various types of Mendelian crosses. results are displayed in Punnett Square format, and resulting genotypes/phenotypes and ratios are displayed

Use this app to check your answers, or better yet, to generate a nearly infinite number of practice problems! Features Dropbox integration for depositing a pdf of practice problems.

Version History Self Test Quiz upgrade:
- Now able to easily install alternative sets of quiz questions using Quiz Code Tokens. New quizzes and associated tokens can be created freely via web app http://quizupdate.genevol.com/
- New Population Genetics quiz (code 'POPGN') delivered standard, in addition to default App quiz (common genetics terms)

Bug fixes:
- Fixed bug in Cross Simulator caused by ios update (was causing crashes when attempting to change organism,)
- Fixed bug in Breeders Equation Problem Solver (was causing occasional crash when parameters resulted in an R/S value > 1)
- Updated support email address (now support@genevol.com) 3.3 03/17/2016 Minor patch release:
- Corrected issue with Refresh in Problem Generator obscuring top line of answer in certain circumstances
- Corrected issue in bulk Practice Document creation causing mis-alignments for some problem types
- Included "distance dashes" in Genetic Cross Mapping problem solver between two genes that are linked (where the third gene is un-linked). Distance dashes were previously only included where all three genes were linked)
- Added Information on iPad HD version and link to upgrade 3.2 02/14/2015 Minor updates:
- In Practice Problem Quick generator, can now tap refresh button to generate a new problem of the same type without leaving the screen
- In Practice Problem Document Creator, now includes a txt version of practice problems (in addition to pdf version) in email export. Also, page separation added between Questions and Answers
- Cross Simulator re-organized to present Settings screen prior to main cross screen
- Minor adjustments to Population Growth Problem Solver: If growth rate entered, disables entry for birth rate and death rate (and vice versa). Subscripts added for N0 and Nt texts
- Allele Freak: correct issue with Fitness input where regional settings set to Sweden (and some others)
- Allele Freak: Auto-clear setting now defaults to "off" (i.e. allows plotting of multiple graphs) 3.1 08/26/2014 New "Cross Simulator" module:
- allows simulation of various types of Mendelian crosses. Results are displayed in Punnett Square format. Genotype/phenotype ratios can be analysed

"Allele Freak" module:
- added "Inbreeding co-efficient" functionality

"Problem Central" module:
- added "Population Growth" solver

"Self Test Quiz" module:
- added functionality to allow customised set of quiz terms to be installed
- Randomised terms now allow no repeats (until all terms have been used at least once)

General:
- Various updates for ios7
- Implemented Analytics (opt out option included)
- Several pop up help/info screens added
- Minimum ios version now 6.1 3.0 12/05/2013 - New "AlleleFreak" module introduced. Tracks and plots the fate of alleles over multiple generations based on relative fitness and genetic drift

- Added link to online manual

- Cross Mapping Problem Solver: Revamped cross mapping simulation engine. Added functionality to predict gene order in addition to phase and linkage. Added functionality to occasionally generate unlinked genes

- Breeder's Equation Problem Solver: Corrected minor bugs

- Added user-definable settings for various options relating to Cross Mapping and AlleleFreak

- Genetics Terms: Added functionality to automatically retrieve updates from the cloud when new terms become available 2.0 09/10/2013 1.0.0 05/29/2013
