An opening
Gregor Mendel is known as the “father genetics”. He discovered Mendelian inheritance. Gregor Mendel, the “father of genetics”, discovered that different patterns were observed when certain traits and gene separation were combined. His experiment was conducted with peas, and he found that traits were more likely to appear in subsequent generations. The three Mendel Principles were The Principles Dominance & Excessiveness, Principles Segregation, and Principles Independent Assortment. Segregation and mutations are often the driving forces behind genetic variation. Phenotypes are the physical characteristics that make an individual unique. In contrast, the genotype of an individual cannot be directly observed but rather is a part of one’s DNA. Homozygosity is the term used when an organism has identical alleles. If the organism is heterozygous and has different alleles than its recessive allele, then it’s classified as homozygous. To find out the probability that an organism has the same alleles its parents, punnet squares can be used. The same as homozygous is dominant homozygous. However, heterozygous dominate gene has two traits. The gene pool of certain individuals has a greater probability of producing specific phenotypes. Natural selection has led to the variation of corn colors. In the laboratory, we talked about two mono-hybrid crosses: a hybrid of yellow starch with purple starchy. When two heterozygous corn plants are crossed, they produce phenotypes in a 3:1 ratio.
Materials and Methods The materials that were used in the experiment are as follows:
One ear purple and yellow starchcorn
One blue mark
Record data with a single pen
One person counts the kernels of corn on the cob while the second records the information. We started by counting vertically from one column. Each kernel had a blue marker to prevent a repeat of the same rows. After recording all the data, the chi-square was used to check if it matched the ratio predicted by the genetic cross. Multiplying the observed total by 0.75 will give you the expected number of purple-colored kernels. Multiplying.25 by the observed total will yield the expected number yellow kernels. The observed value for purple starchy was 3.6:1.
DiscussionThe hypothesis states that when two heterozygous violet corn plants are crossed in monohybrid, the phenotypes produced have a 3:1 ratio. This hypothesis is well-supported by the ratios of group and class, which equal 3.6:1. The dominant heterozygous trait we observed in the corn ear was purple, as opposed to yellow starchy. When the data from the group was compared with the data of the class, they both had the same ratio between purple starchy and yellow starchy. The data collected by each class helps to provide a greater understanding of what corn species are being handled. Genetic variation in the corn or mutations may provide an alternative explanation to our hypothesis. The observed ratios of the corn pieces were similar, but no two were identical. This reveals the diversity in genetics amongst organisms. Transposable elements were responsible for the yellow kernels with purple specks. Some genes can move around on chromosomes, causing color changes on the kernel.
ConclusionThe results obtained from the experiments are more than what was anticipated. The ratio between purple starchy grains and the white starchy ones exceeded 3:1.
