What is difference between genetics and genomics?

Image
Genetics is the study of genes and how they affect heredity, or how specific characteristics or disorders are passed down from one generation to the next. The scientific study of genes and their effects is known as genetics. Protein-making instructions, which are carried by genes, control how cells behave and how the body works. Cystic fibrosis, Huntington's disease, and phenylketonuria are a few examples of hereditary or genetic illnesses. Genomics is a more recent term that describes the study of all of a person's genes, including relations of those genes with each other and with the person’s terrain. Genomics includes the scientific study of complex conditions similar as heart complaint, asthma, diabetes, and cancer because these conditions are generally caused more by a combination of inheritable and environmental factors than by individual genes. Genomics is offering new possibilities for curatives and treatments for some complex conditions, as well as new individual sty

What are the difference between Male and Female Genetic?

Men and women share around 20,000 genes in common. Only the physical differences in the sex chromosomes can be distinguished from one another. It is only guys who have the Y chromosome. Despite the X chromosome being present in both sexes, females have two copies while males have just one. The X chromosome is one of two allosomes that determine sex in both men and females of many organisms, including mammals. It is a part of both the XY and the XO sex-determination systems. Early researchers named the X chromosome for its particular characteristics, which led to the subsequent discovery of its counterpart, the Y chromosome , which was named for the following letter in the alphabet. Males have one X and one Y chromosome, while females have two X chromosomes. Early in the development of the female embryo, one of the two X chromosomes is arbitrarily and irreversibly inactivated in cells other than the egg cells. This process is known as X-inactivation or lyonization. The Y chromosome is

What diseases can Pre-implantation genetic diagnosis(PGD) detect?

  Pre-implantation genetic diagnosis is a method used in conjunction with in vitro fertilizations, or IVF, that enables testing of embryos for specific traits like their chromosomal make-up as well as testing for genetic illnesses that are handed down via families. In vitro fertilizations  and preimplantation genetic diagnostic tests can be done on a couple's embryos to determine whether one or both partners are carriers of a genetic mutation that could cause a major medical problem in the kid. In the past, couples with a genetic mutation had the option of choosing not to have children or having prenatal testing done with either amniocentesis at around 16 to 18 weeks of pregnancy or with chorionic villus sampling at around 11 to 12 weeks to determine whether the baby was affected by the genetic condition. In case the unborn child has the disease, the couple then has the choice to abort the pregnancy. Nowadays, carriers of genetic illnesses have the option of having IVF and PGD per
