and 10th chromosome, that all show similar result among homosexual males (MD, 2005). The regions on the 7th and 8th chromosome were associated with male sexuality whether the gene came from mother or father, but the 10th chromosome were only associated with male sexuality if they were inherited from the mother (MD, 2005). If an individual were wanting the “gay gene” removed from the future child it would most likely effect the 10th chromosome. With the change of the 10th chromosome it could…

19th century. Haemophilia was known to be a recessive sex-linked disorder as it is carried down generations through the X sex chromosome. Since males have one X and one Y chromosome, if their X chromosome contains the gene for haemophilia, then the males will have this disorder. As a result, haemophilia is mostly likely to result in men. If women were to have an X chromosome with the defected gene, than they would be a carrier of the disease (Pemberton 2011). While women may not experience the…

visible, this is when we can start to see the chromosomes, or condensed DNA. During metaphase, the chromosomes are connected by spindle fibers and all of the chromosomes are aligned in the middle of the cell, the sister chromosome are connected by the centromere. Errors in this phase can happen when the spindle fibers are connecting and connect to an uneven amount of chromosomes. In anaphase, spindle fibers connect to centromere and pull the chromosomes to the opposite end of the nucleus. An…

doesn’t take up most of my time but it’s a very important part of my day. The chromosomes line up across the center of the cell.…

90 percent of unborn babies diagnosed with Down syndrome are aborted (19). Everyday, all around the world babies are diagnosed with Down syndrome and parents are facing this choice. Down syndrome is a physical and mental disorder resulting from a chromosome malfunction in their DNA. Down syndrome is a complex disorder that can have a wide range of effects and little to no treatment, resulting in patients having…

Body Planes, Regions, Cavities, and Directional Terms The fundamentals of learning the body in the medical field are body planes, regions, cavities, and directional terms. First up are the body planes, which the definition of a body plane is simply a two-dimensional surface. The dimensions of the body plane are both of length and of width and the body planes are used to describe the different locations that are located in the body or are just used for the point of location. There are three…

only carried on X chromosomes, never on Y chromosomes. Therefore, it is often carried by females but expressed by males. This is because females inherit two X chromosomes, one from their mother and one from their father. If one of the X chromosomes that a female inherits is flawed (carrying the defective gene) her other healthy X chromosome will allow her body to make sufficient clotting factors. However, males inherit one X chromosome from their mother, and one Y chromosome from their father…

pairs with T. DNA is the blueprint of life. Humans have 46 chromosomes. Our entire DNA sequence is is called a genome. The average gene is 10,000 to 15,000 bases long. DNA can be extracted from many different types of samples: blood, cheek cells, urine. Alleles are forms of of the same gene with small differences in their sequence of DNA bases. Genes are made up of DNA. There are about 20,000 important genes located on one of the 23 chromosome pairs found in the nucleus or on long strands of DNA…

malaria. Malaria weakens the immune system’s response to Epstein-Barr, which allows it to change infected B-cells into cancerous cells. Chromosome affected: The c-myc gene on chromosome 8 is affected. Symptoms: Symptoms include fever, night sweats, swollen lymph nodes, intestinal…

extra copy of chromosome 21. Dr. Jerome Lejeune; a French physician discovered that being "mongoloid" was a result from a chromosomal abnormality, which meant the…
