The convergence in external morphology of sharks‚ penguins‚ and porpoises is attributed to selection pressures that are common to these groups Genes that are located on the same chromosome are all of these An incompletely dominant gene controls the color of chickens so that BB produces black‚ Bb produces a slate-gray color called blue‚ and bb produces splashed white. A second gene controls comb shape‚ with the dominant gene R producing a rose comb and r producing a single comb. If a pure-breeding

of 10 TOPIC 1: MENDEL’S 1ST LAW‚ SEX AND BLOOD GROUP DETERMINATION Learner Note: Mendel’s Laws are very important and you must understand the basic concepts of Genetics. You must understand the concepts of dominance and how this plays a role in monohybrid crosses (mono = one = one characteristic or trait). Be aware of confusing the word ‘cross/ crossing’ with ‘crossing over’ in Meiosis. You cross individuals and calculate the chances of a characteristic or trait being in the offspring. “Crossing

fly’s have for distinct stages‚ the egg‚ larva‚ pupa and adult. the egg and larva stages last for eight days‚ the pupal stage last for six days and then the adult stage which last for many weeks this period of growth is called instars. In this lab a dihybrid cross was performed to get data results and to draw a conclusion to the hypothesis. The hypothesis for this experiment is that it will yield a 9:3:3:1 ratio XY‚ Xy‚ xY‚ xy. Which is that 9 out of 16 would have long wings red eyes‚ 3 out of 16

Fruit Fly Lab Alycia Fletcher Biology IB HL March 25th 2010 Fruit Fly Lab Introduction Genes can either be sex-linked or autosomal. If a gene appears mostly in one sex chances are the gene is sex-linked and if it appears frequently in both sexes it is most likely autosomal. Using Drosophila melanogaster‚ also known as the fruit fly‚ we will determine whether the gene is sex-linked or autosomal. Drosophila melanogasters have a relatively short life span and are an excellent organism
