Monohybrid cross in corn introduction: a cross between individuals that involves one pair of contrasting traits is called a monohybrid cross first we will use punnett square diagrams to predict the results of various monohybrid crosses we will then examine ears of corn purple results from the dominant allele (p), and yellow from the recessive.

Ap biology lab 8: population genetics report conclusion mendelian genetics of corn • recognize contrasting phenotypes • collect data from f2 ears of corn segregation and analyze the results from monohybrid and dihybrid crosses • study dominance and independent assortment of alleles in corn • compare predicted results with. Introduction: this laboratory investigates a dihybrid cross as shown in the above photo of an ear of corn the four different genes and grain types are identified in the following photo, and the complete cross is shown in table 1 below. Use the monohybrid and dihybrid cross probability spreadsheets, coin toss, chi-square probability chart and the data collection sheet - genetics (see above) you need to follow the same procedures for these three lab activities, except the corn kernel analysis will be as images. Corn genetics lab report february 20, 2015 uncategorized dsudesh2000 in my biology honors class, my lab group and i conducted an experiment to apply our newfound knowledge of genetics – using multicolored and multi textured corn. The corn grains used in this experiment are the f2 generation of a cross between homozygous dominant corn and a homozygous recessive corn theoretical questions 1 mendel’s second law, also know as the law of independent assortment, is a conditional law of genetics because it only applies when the genes are on separate autosomal chromosomes.
Monohybrid cross, recessive gene, dominant gene, maternal, penny represents, expected probability, resulting offspring, allele and tails, percentage, mendel predicted this is lab manual for an experiment all required instructions for experiment are given in this handout few points are given above from this manual. Table two in the attached lab report shows that the chi-square calculations gave us a p-value of 006 which made it failed to reject the null hypothesis the chi-square calculation sample can be observed in the methods and materials section of this lab report. Genetic corn seed, green:albino is rated 48 out of 5 by 6 y_2018, m_10, d_12, h_2 growing this corn for a monohybrid lab helps the students visualize the phenotype using corn as an example is also good because most of my students come from a farm background so they tend to ask more questions about the corn and how it was created. 2 lab #4: genetics & inheritance work in groups of two this lab is designed to demonstrate genetics, or the study of how heritable characteristics are passed from generation to generation genetic traits are determined by genes, or small segments of dna carried on chromosomes that determine physical characteristics. The dihybrid cross had for grain phenotypes in the ear of genetic corn and they were red and smooth (rs), red and wrinkled (rs), yellow and smooth (rs), and yellow and wrinkled (rs) in addition to our previous dominant and recessive genes of red (r) and (r), s represents a smooth texture dominant to s which is a wrinkled texture.
