“People with autism spectrum disorder (ASD) demonstrate characteristics of impaired social interaction and communication abilities. These clients are unable to initiate conversations and fail to understand or observe nonverbal behaviors. Another identifier for someone with ASD is their use of repetitive and restrictive behaviors. A client with ASD will repeat the question being asked rather than answer it. The client will parrot or repeat one word or phrase that is spoken to them, also known as…

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…

caused by a mutation in the ATP6V1B2 gene on chromosome 8p21 or a mutation in the KCNH1 gene on chromosome 1q32. It affects individuals who are of Eastern Indian ancestry from India and the West Indies and also individuals from European descent. Zimmermann Laband Syndrome is inherited as an autosomal dominant trait, but also may exist as an autosomal recessive trait. This disease is genetic and can only be inherited. Scientist have also found a gene on chromosome three that may cause some cases…

Turner’s syndrome is a condition that results in a person only being born with one X chromosome. This condition is due to when someone is born with only one sex chromosome. Those who have Turner’s syndrome have one X-chromosome and are missing the other sex chromosome. Because there is the presence of an X chromosome only those with Turner’s syndrome are consider having the sex of female. This syndrome results in a vast variety of medical issues, but most issues that those who have this syndrome…

Chromosomal inheritance relates to how a person has 2 sets of chromosomes, 46 in total, that they inherited their parents. Chromosomes carry the genes, particularly the alleles that the offspring inherit. Gregor Mendel had no understanding of chromosomes when conducting his studies. He experimented and tested peas and discovered that some genes were dominated (showed up) while others were recessive (hidden). What he didn’t know was that chromosomes contained the genes that were responsible for…

and determine the crosses of the tan x wild type (black), gray x wild type (black), and tan x gray spores of the Sordaria fimicola. To accomplish the crossing, the plates filled with auger had to be set up with each individual kind of spore. Three plates with two different spore colors of sordaria in each. One plate was black and tan, black and gray, and gray and tan. For gene to centromere distance the standard deviation was 5.6 (tan x wild) and 4.8 (wild x gray). For part two, the linkages for…

helpful or neutral). An example of this is blood type in humans which is passed onto new generation and is not an advantage or disadvantage, but neutral. There are two kinds of chromosomes that are present inside cells and that are passed on to offspring during sexual reproduction. These are autosomes and sex chromosomes mutations in each determine. Some traits however can be harmful. An example of this are diseases that are present in an organism because of a mutation in the DNA of the…

important to understand which genes and alleles are present in which chromosomes, what the function and phenotype of the corresponding gene is, and if multiple genes are significantly linked and do not separate independently during meiosis. The results of this experiment have verified that the autosomal gene that control long versus apterous wings separates independently from two genes controlling eye color: one autosomal and one X-linked. This should pave the way for future studies, which…

different Chromaseratops offspring. It is like that because of meiosis. That process creates the cells and gives them chromosomes which become homologous pairs. From there, you can make a lot of different combinations of gametes. For this lab, there was 8 different gametes since there was 3 homologous pairs. For a human there would be way more combinations since we have 23 pairs or 46 chromosomes. Through independent assortment, you receive 2 homologous pairs which can be from the same gene, but…

Triple X Syndrome (Trisomy X) Genetic Disorders are diseases inherited through genetics. These disorders are usually scarce in number but affect one in thousands or millions of people. Trisomy X or Triple X syndrome is a genetic disorder that causes there to be three X chromosomes in a woman’s body. Trisomy X was discovered by a scientist named Patricia Jacobs in Edinburgh, Scotland. It was later named “XXX Syndrome” by a British pathologist and geneticist named Bernard Lenox after Patricia…
