  • Chromosomal Inheritance

    Chromosomal inheritance relates to how a person has 2 sets of chromosomes, 46 in total, that they inherited their parents. Chromosomes carry the genes, particularly the alleles that the offspring inherit. Gregor Mendel had no understanding of chromosomes when conducting his studies. He experimented and tested peas and discovered that some genes were dominated (showed up) while others were recessive (hidden). What he didn’t know was that chromosomes contained the genes that were responsible for…

  • DNA Damage And Repair In Vascular Disease

    1. In your own words, define what is a mutation? Abnormal inherited or acquired permeant alteration in the sequences of the nucleotides of the deoxyribonucleic acid of an organism may or may not change organism phenotype, it occurs with a frequency of less than1% among a population. 2. Are mutations bad or good for you? Justify your answer in either case Mutations could be good, bad, or may have little or no effect. Beneficial mutations: Some mutations if they happen they have a positive…

  • Pros And Cons Of Artificial Selection

    PSS is not the only example of when artificial selection has gone wrong. There are many positives to artificial selection people just need to become educated and make sure they are not breeding for genes that can have adverse reactions, other than what was originally expected. This does raise the question of the ethics of artificial selection in relation to the quality of life the pigs will have living with the stress gene. Humans have been doing artificial selection for a long time with many…

  • The Notch Signaling Pathway Paper

    The small genome and the short life cycle of Drosophila melanogaster makes the use of this organism proper to understand the role of signaling pathways, mainly the Notch signaling pathway, in the development of sensory organs in organisms. The molecular interactions of some genes with the Notch signaling pathway can help us understand cell differentiation in sensory organs. The gene Hairless shows high levels of interaction with the Notch signaling pathway of Drosophila melanogaster. Hairless…

  • Chi Square Test Lab Report

    Theses certain cells are called our sex cells or gametes which are sperm cells in men and eggs in females. This is how sickle cell is passed on to each generation. If one parent maintains the allele that codes for sickle cell, then there is a possibility their offspring will as well. Meiosis happens in two stages called Meiosis I and meiosis II. Within Meiosis I, there are four phases that occur called prophase I, metaphase I, anaphase I, and…

  • To The Bitter End Case Study

    When both parents are taster and their children not that means that the parent has alleles that are heterozygous dominant therefore their children possess the capability of not being a taster of PTC. 4. The consequence of having a parent that cannot taste the PTC will result if having children that can taste the PTC means that the PTC has…

  • Alopecia Areata Research Paper

    Alopecia Areata Alopecia Areata is a common autoimmune disease that affects the hair growth. Although this disease is only passed through genetics, but it differs from a single-gene disease. Both parents have to contribute a certain number of specific genes in order for their child to get this disease. Because of this it is rarely passed from parent to child. Now for identical twins it is much different. There is a very low chance that both twins will get it. There is only a 55% for each…

  • Meiosis Cell Cycle

    Genes are what parent passes on to their off spring. The reason that the off spring don’t look identical to the parent is due to a process called crossing over during meiosis.. Meiosis creates new cells that contain different data than that of the parent due to the genes getting shuffled around by cross linking. The chromatids which are parts of the chromosome cross over bits of data making the new cell unique from the parental chromosome. Dividing this way will ensure that the genes will be…

  • Differences And Characteristics Of Bianca, Bianca And Gialla

    3. Results Considering the morphological characteristics of the ecotypes, the cladode shape was elliptic or ovate, the number of spines varied among three classes (many, intermediate or few), the flowers had two types of petal color (scarlet or yellow), the fruit was elliptic or ovoid and the pulp color was white, pale yellow or orange (Table 2). The OFI populations studied showed statistically significant differences for DM of the fruits, F (17, 34.24) = 31.61, p < 0.05, which varied…

  • Mendel's Law Of Genetic Analysis

    breeding of pea plants Mendel formulated from his observations a 9:3:3:1 ratio of phenotypic traits in the second filial generation. Thus he formulated the law of independent assortment which will be examined in this experiment. This law states that alleles for different genes separate independently during gamete formation (Reece et al., 2011). The Drosophila Melanogaster is the organism used to study Mendel’s proposed patterns of inheritance because of its obvious advantages in that it is…
