Lesson 2: Assignment 1-Genetic Information Resources, Assignment 2- Critical Thinking Exercise, and Assignment 3-Definition Matrix Tabytha Balash Ohio University  Assignment 1: Genetic Information Resources There are several areas to retrieve information on genetics. The following paragraphs will summarize three organizations that provide information on genetics, genetic counseling, and genetic testing. The summary will include what information is obtainable from the site, who supports the…

Your DNA is relatively free from mutation DNA is constantly replicating itself in your cells to grow, which can lead to some errors in replication and recombination, and is also subject to bombardment from environmental factors everyday (such as UV rays or cigarette smoke, which can damage DNA and lead to cancer.) This leads to more than one quintillion DNA changes in one day, and you’re probably asking how you don’t have superpowers already. DNA mutations can be dangerous, and often cause…

Comparative morphology is the study of the anatomical patterns of structures within an organism’s body and how it allows the taxonomical categorization of a species. The anatomy of an organism is significant to the functions of that particular body part of the organism (Kardong, 2015). To be able to compare the structures of an organism allows emphasis in particular themes of the vertebrae structures. The functional morphology of an organism includes the study of the relationships between…

1. Introduction The most recent research lines are based on understanding wild paralarvae behaviour and prey preferences, refining paralarval nutrition and rearing conditions for O. vulgaris welfare (Iglesias and Fuentes et al., 2014). In the culture of cephalopods, the paralarval life stage is a critical period, especially for octopuses. During this period, the paralarvae must initiate the consumption of a suitable diet to grow, requiring stable conditions for proper development (Iglesias &…

had fused with an unknown embryo during gestation and had retained the differing DNA of that embryo” (Granzen, 2014). All along “Karen was a whole-body chimera, otherwise known as a tetragametic chimera, meaning she resulted from the fusion of four gametes--two eggs and two sperm” (Hutchison,…

The ethical issue that I feel everyone should be aware of states the morality of parents using pre-implantation genetic diagnosis (PGD) to achieve the same disability that they have. Parents use that process to select an embryo of a disability or a disease to acquire the same characteristic as the parents. In the case study Causing Deaf Children, a lesbian couple chose a sperm donor that was deaf to ensure that their child would also be deaf like they are. This is an ethical problem because most…

Discussions concerning the ‘social construction’ of gender generally revolve around the premise that gender is not an intrinsic aspect of a person. Rather that it is something which has come about through the formation of societal ideas surrounding what it means to be a man or a woman. Arguments in opposition to this may draw their reasoning from biological differences between the male and female sexes as evidence of a natural divide between men and women, which could promote the attribution of…

pregnancies. Assisted reproductive treatment is a widely accepted method for treating patients that suffer from infertility. There are many different methods to achieving a pregnancy through ART some being (ICIS) intracytoplasmic sperm injection, gamete intrafallopian transfer (GIFT), and In vitro fertilization to name a few. Although the pregnancies themselves are much desired the outcome of multiple fetuses is not. In order to resolve this iatrogenic problem doctors use fetal reduction as a…

Living organisms are made from cells. There are two types of cells: Prokaryotic and Eukaryotic. Prokaryotic cells do not contain a nucleus or membrane bound organelles. Eukaryotic cells are more complex because they contain both. Plants and animals are made from eukaryotic cells, but they are different. Plants have a cell wall that provides more structure and the also have chloroplasts that help them carry out photosynthesis. Animal cells have neither of these. Stem cells are a unique type of…

Selective breeding is the human interference in the genetic transfer in animals and plants. Humans take the idea of natural selection where instead of the environment selecting for the alleles that are best suited for the organism to survive in the wild, humans select rare desirable phenotypic traits in organisms and breed them with each other in order produce an offspring containing those traits. Desirable traits include leaner meat in animals, or better quality milk in cows for commercial uses…
