Gregor Mendel was the first person to make connections between parents and children by using math symbols. He made the set of laws which are now known as the three laws of inheritance. This set of laws consists of the Law of Dominance, the Law of Segregation, and the Law of Independent Assortment. To begin, the first law of inheritance is the Law of Dominance. This law states that genes come in pairs and are inherited in different units called alleles. In a situation with one dominant allele and…

Oh, Babies! Figure 1: Twin babies When you saw multiple on your ultra sound, what did you do? You are certainly getting more than you bargained for! Did you question whether you were seeing multiple or question your prescription? Having multiple babies, specifically twins, is perfectly normal! Twins are now on the rise; every one in thirty babies is a twin. This article helps simplify the science of twins for you, so you know exactly what is happening in your body or your wife’s body! Twins…

1) Which genome engineering mechanism they used to create transgenic ES (Embryonic stem cell)? What is the goal of this transgenesis? Answer: They chose to mutate Sos1 because it showed more expression in tissues and cell lines than Sos2. After they tested which Sos gene had more expression, they moved on to mutating Sos1 in murine ES cells using homologous integration of a lacZ-neor cassette. This cassette was placed in front of the Sos1 coding sequence. The goal was to integrate this cassette…

provides an increased understanding of how nutrition affects metabolic pathways. “Nutrigenomics is the new strategy in nutrition research that will lead to its development towards Nutritional Science 2.0”(Nutrigene.4t.com). It also shows the relation of genotype-phenotype to define an individual 's personal health. This means that since nutrigenomics was developed after the 20th century, it has been restoring people’s health such as preventing diet-related diseases to create a nutritious…

Clonality is homogeneity in the genotype of cells originating from a specific linage. One cell like the other, expressing the same set of genes to carryout functions that they have to do as a tissue; a causality of cells having a common ancestor or a progenitor cell which can be sourced at one point in time of development of an organism. This expansion of one cell into various clones occurs via a process called clonal expansion. The process is not different in cancer cells, there is one cell…

always used the term race, but what they have not done is define how they are using the term. Everyone knows what “race” is but not everyone has the same understanding of what race is. Do we define race biologically or geographically? Do we use genotypes or phenotypes when classifying race? Is the race concept biological or is it socially constructed? All of these questions will have been answered by the end of this paper. In this paper, I will explore how anthropologists in different fields…

Introduction Background While the clinical validity of genetic tests is growing, there emerges a concern that the disclosure of individuals’ genetic test results could lead to discrimination by health insurers and employers (Hudson et al., 2008). Federal legislation addressed the protection of individuals’ genetic information by passing the Genetic Information Nondiscrimination Act (GINA) in May 2008. The law prohibits health insurers and employers from using an individual’s genetic…

Mitosis is a process of cell division resulting in two genetically identical daughter cells developing from a single parent cell. Meiosis is a type of cell division resulting in the production of sperm or eggs that have half the chromosomes of the parent cell. Mitosis and meiosis are similar in a way that they are both ways in which cells reproduce. Mitosis and Meiosis both occur in humans and animals. In both cases (Mitosis and Meiosis), cells copy DNA and make new cells based on the…

The subject these scientists are interested is the brain. They want to know whether the abnormal spindle gene (ASPM gene), important for encoding human homologue for spindle function, is responsible for an abnormal brain growth disorder (MCPH). They know that during primate evolution there has been a significant increase in brain growth, but are unaware of what causes this increase. The central nervous system is the only thing being affected by individuals whom have MCPH. To test their…
