possible theories may explain these such as habitat loss due to the urbanization of Area 2, human impact, and nest predation. The Hardy-Weinberg principle states that the allele and genotype frequencies of a population will remain constant as long as population remains large. Thus, a change in the population may change the allele and genotype frequencies which may change the observed heterozygosity. Due to the amount of human interaction, the bottleneck effect, which occurs when the size of a…

Meiosis is a type of cell division that occurs in sexually reproductive organisms that leads to the production of reproductive cells called gametes. The process of meiosis begins with a diploid (2n) cell, which has a full amount of chromosomes. For example, in humans, the diploid number is 46. Meiosis gives the end product of four haploid (n) gametes, which have half of the amount of DNA that their parent cells have. In humans, this haploid number is 23. The process of meiosis has many steps…

is a heterozygote, in which case the child can be affected if either a new mutation occurs on the gamete inherited from the other parent, or uniparental disomy occurs resulting in the child inheriting two copies of the heterozygous parent’s mutant allele. When calculating risks in autosomal recessive inheritance, the underlying principle is to establish the probability that both the parents are carriers and then multiply the product of these probabilities by ¼, this being the risk that any child…

affects lipid accumulation, vascular remodeling and plaque instability resulting in cardiovascular disease. Human MMP-3 gene is found on chromosome 11q22.3. The wild type promoter contains 5 consecutive A residues (5A allele) while the mutant contains 6 consecutive A residues (6A allele), resulting in a decrease in the stromelysin-1 levels. Any decrease in stromelysin-1 levels decreases proteolytic activity, increases extracellular matrix deposition thus causing artherosclerosis. There are…

Complete Name: Unit 4 Student Name: Carroll, Nicholas ********************************************************************************************************** 1. Describe Mendel's P, F1, and F2 generations in his experiments with pea plants. Student Answer: Mendel's F1 generation, also known as the first filial generation is the parent of the offspring generation which is the F2 generation(Daempfle,2016). The P generation is the also known as the parent generation. The parent…

PURPOSE The purpose of this lab is to acquire the ABO blood type of four unknown individual’s samples through a series of steps. Blood typing consists of a test in which ultimately determines an individual’s blood form. This procedure is an essential process for those who need blood transfusion or those willing to donate blood. The reason this stage is compulsory is because not all blood is compatible. Potentially a fatal transfusion reaction can occur if a unit of blood containing an ABO…

Gaucher disease is on gene GBA; 2629 (Pastores, Hughes, YEAR). The alleles of the GBA gene are not yet known, however, there have been multiple testings’ of southern blots. Although, due to the lack of nomenclature (base pairing) understanding, there has not been a definite number of alleles found (Futerman and Zimran, YEAR). Yet, one study was able to find a few mutant alleles. The results of this study found one mutation consisted of a single-base substitution in three…

Heavier Procambarus clarkii have higher success rates in agonistic interactions Animals in a community are always competing with one another for the resources that the area has to offer such as food, space, and water. Often, this competition can escalate into a violent confrontation. For Procambarus clarkii, these confrontations can result in losses of antennae, limbs, or even lives. To avoid this, clarkii size each other up before engaging in combat to determine if dominance is worth the risk,…

neuropsychiatric disorder is thought to be influenced by microRNA abnormalities that provide psychological markers traceable through a patient’s genome to afford early detection (He 2017). Genomic studies uncovered that schizophrenia can be caused by various alleles in a genome that interact together. Signs and symptoms of the disease are linked through the Disconnection hypothesis that allows for molecular and neuronal pathophysiology. This pathophysiology allows for receptor functions and…

According to the National Institute of Neurological Disorders and Stroke, there are more than 600 neurologic disorders 1. Neurodegeneration is one of the main contributors to Alzheimer’s, Parkinson’s, and Multiple Sclerosis. Neurodegeneration is the debilitating condition along with those diseases, which results in the healthy, functioning nerve cells to deteriorate and slowly die off. Deterioration gradually leads to the loss of cognitive skills, motor skills, and eventually death of the nerve…
