A monohybrid cross is one that the parents have different alleles and only shows results for one trait. 3. Steps to create a Punnett grid: children letter to show the alleles determine the parents genotypes: all the possibilities determine the gametes

There are things that make you more likely to have a mutated gene‚ these include: ionising radiation and chemical mutagens like

INTRODUCTION TO SCIENTIFIC TERMINOLOGY The purpose of this document is to introduce root words and their definitions. These words play a vital role in Biology because many scientific terms are based on these words. Because these root words are Greek or Latin in origin‚ their meanings have remained consistent throughout time. By becoming familiar with root words and their definitions you can determine general meanings of many terms by simply applying these root word definitions. For example‚ the

Introduction In most kitchens the small flies that are found are Drosophila Melanogaster also called fruit fly. They are often brought in by ripened tomatoes‚ grapes and other perishable items from the garden. Drosophila melanogaster is a little two winged insect about 3mm long two winged insect that belongs to the Diptera‚ the order of the flies. The drosophila egg is about half a millimeter long. Fertilization takes about one day the embryo to develop and hatch into a worm-like larva. The larva

Chi-square requires that you use numerical values‚ not percentages or ratios. Then calculate 2 using this formula‚ as shown in Table B.1. Note that we get a value of 2.668 for 2. But what does this number mean? Here’s how to interpret the 2 value: 1. Determine degrees of freedom (df). Degrees of freedom can be calculated as the number of categories in the problem minus 1. In our example‚ there are two categories (green and yellow); therefore‚ there is I degree of freedom. 2. Determine a relative
