major types of genetic data.” There is autosomal, Y chromosome, and mitochondrial DNA. Autosomal is a combination of your mother and father’s DNA that makes you. Y chromosomes come from your father and are given to a son, and mitochondrial DNA comes from your mother. Everyone has the autosomal and mitochondrial aspects of genetics. The mitochondrial makeup is just what genes you got from your mother. However, only males have the Y chromosome aspect of genetics since males sex genes are comprised

karyotype displayed in Figure one. There were 23 sets of chromosomes, each set containing two chromosomes. There were two karyotypes with an extra chromosome. The karyotype in Figure three had an extra chromosome 21 and the karyotype in Figure four had an extra chromosome 23. There were also two karyotypes displaying an absent chromosome. The karyotype in Figure four was missing a chromosome seven and the karyotype in Figure five was missing a chromosome 23. The chromosomal abnormality that appears in the

The first male chromosome that meets and unites with the egg determines the gender of the offspring. If Y chromosome from the male first unites with the egg (which is an X chromosome), the offspring is male (XY). But if an X chromosome coming from the male first unites (XX), the gender of the offspring is female. 2. The successful sperm cell penetrates inside the ovum. The

X and Y chromosome. Females however, are born with two X chromosomes. A female with Fragile X in one chromosome may not necessarily have Fragile X within the other chromosome. Within the female, certain cells may choose to activate one of the X chromosomes, and other cells may choose to activate the other X chromosome. Hence, even though there exists a Fragile X chromosome, not all cells within the body will use it, thus the production of FMRP is possible using the other normal X chromosome.

of chromosomes in diploid human cells was 46-not 48 as had been believed for the previous thirty years. In the earlier years of the research, experimenting, and treatment testings, they discovered the cause of Jacob’s syndrome. Jacob’s syndrome is a rare, chromosomal disorder that affects males. It is caused by the presence of an extra Y chromosome rather than the typical male possession of one X and one Y chromosome meaning that individuals with this syndrome have one X and two Y chromosomes. With

hypothesis that the environmental conditions such as heat of the male during the intercourse and the maternal nutrition determined the sex in mammals. This was proved wrong in the early 20th century by Painter TS who reported a sexually dimorphic chromosome in humans. The influence of environment in the sex determination was also proved true in certain species (Painter TS, 1923). The most common genetic problems that result in disorder of sex development (DSD) has raised the importance for the

name of Felix Hoppe-Seyler discovered that in the nuclein there were many smaller molecules with phosphates and sugars along with nucleic “bases”. In the 1800’s a group of scientists observed that when two cells divide they evenly split up their chromosomes, and later on more scientists discovered that

Born Criminal? A theory that the genetic composition of a human individual increases their likelihood of committing violent crimes. Does the “XYY chromosome theory” exist, a genetic syndrome that causes violent crime? There are many different arguments about what really causes violent crime. Crime is defined as an action or omission that constitutes an offense that may be prosecuted by the state and is punishable by law (Oxford 2017). On one side, people believe that crime originates from an individuals

sperm and one female ovum combined. This single cells contains all of a person's genes. Humans have 46 chromosomes, 23 from the mother and 23 from the father. Chromosomes contain instructions that a person needs for the rest of their life and for growth. Human's have close to 20,000 genes, each gene directs the way to make sepecific proteins. A gene is just a part of a chromosome, while a chromosome

to diseases. Chromosomes carry genetic mutations that cause a number of life-threatening diseases, including muscular dystrophy and hemophilia. Because women have two X chromosomes, a female with an abnormal gene on one of her X chromosomes can use the normal gene on the other and thereby avoid the expression of disease even though she is still a carrier of the defect. Men, in contrast, have one X chromosome and one Y chromosome, and so they cannot rely on an alternative chromosome if a gene on one
