What are the general findings of identical twins separated at birth? Identical twins separated at birth are not only in looks, they similar in behaviors throughout life, good or bad grades, use or non-use of alcohol, use or nonuse of illegal drugs, and type of family they get as adults. The text states that studies "clearly show that MZ (monozygotic) twins were far more similar in the traits of criminality." (Schram, & Tibbetts, 2014, p. 112) What implications do these findings have for the…

Insoo Cho Dr. Danzi Engoron BI356 Genetics Currently, there are more than 600 genetic disorders known, all caused by defective genes. Genetic disorders result from the accumulation of the harmful substance in the body or from an inability of the body to produce or utilize essential substances that influence development and function. Most of the time genetic disorders are passed down through family, however, sometimes they can also be due to gene mutation caused by a combination of both…

Drosophila Melanogaster, or better known as the common fruit fly, is found all over the world and referred to as the cosmopolitan species (Mitrick, 2010). This fruit fly has three main body parts, which include the head, the thorax, and the abdomen. On males, the bottom half of the abdomen is black, while on the female, each segment of the abdomen is striped black. Drosophila have four main stages to their life cycle. These include: egg, larva, pupa and adult. The eggs small and translucent eggs…

reproduces many offspring and the offspring are created in a very fast fourteen-day cycle. The mutations are easy to identify because the traits that are affected are noticeable. (1) It contains only a few chromosomes. The only ones that contain a significant amount of genetic information are chromosomes two, three, and X. The female…

For a century, scientists studied chromosomes by looking at them under a microscope. In order for chromosomes to be seen this way, they need to be stained. Once stained, the chromosomes look like strings with light and dark bands, and their picture can be taken. A picture, or chromosome map, of all 46 chromosomes is called a karyotype. The karyotype can help identify abnormalities in the structure or the number of chromosomes. To help identify chromosomes, the pairs have been numbered from 1 to…

fissions of the nucleus which result in four gametes or sex cells. Each cell possesses half the number of chromosomes of the parent cell. The process of meiosis occurs…

CHROMOSOME SYNDROMES 14 What is RING14 syndrome? RING 14 indicates an aberration with respect to chromosome 14, which takes the form of a ring as soon as its two extremities, the long arm and the short arm, fuse together. The fusion occurs through two ruptured events, one at the extremity of the short arm and the other at the end of the long arm, which usually leads to a partial loss of the informative genetic materil of chromosome 14. The chromosomal abnormality can…

the loops contained tiny parts where a protein is called CTCF.Researcher found large parts of gene looped together. There were a lot of experiments that took place in my article talking about looping and folding DNA.They also talk about Y chromosome and X chromosome with the 3-D experiment. Folding happen in cancer cells they can use 3-D maps to help find a cure. This is just some of the experiments they did in the article I…

concept of race is a social construct, but unfortunately it is still used around the world. The video shows that everyone came from a scientific Adam and Eve and how it all started in Africa. Even though there are a lot of variations in a few DNA chromosomes around the world, African DNA and its unique variations of DNA show that it is indeed in Africa where all of our ancestral DNA can call…

weaken the musculoskeletal system. Muscle Dystrophies are characterized by muscle weakness, defects in muscle proteins and the death of muscle cells and tissue. Duchenne Muscular Dystrophy is one of many types found and it passed down through the X chromosome. DMD is one of the most common muscle diseases found in early childhood. 1 in 3500 boys are born with DMD however very rarely affects girls with a 1 in 50million chance. It is caused by a small mutation in the DMD gene and it is inherited…
