Other genetic disorders are associated with the X (female) or Y (male) chromosome and are called sex-linked disorders because the X and Y chromosomes are related to sexual characteristics in humans. Finally, the development of some genetic disorders involves environmental factors, factors present ou...
In humans, genes code for traits that can include visible features like the type of earlobe, eye color, or the presence of freckles. Genes can also code for diseases that can be passed from parent to child. Traits such as eye color are inherited by children from their parents. Different...
Discover the process of genetic recombination. Learn the recombination definition, when it occurs, and what happens if errors occur in genetic...
Often, these kinds of mutations lead to the death of the animal soon or a few days after its birth. In humans, genetic disorders are often due to a mutation involving an altered gene or chromosomal aberration. Sickle-cell disease, for instance, occurs when the 20th nucleotide of the gene ...
Sex chromosome, either of a pair of chromosomes that determine whether an individual is male or female. The sex chromosomes of human beings and other mammals are designated by scientists as X and Y. In humans the sex chromosomes consist of one pair of th
Females usually pass the condition (defective phenotype) on to one-half of their sons and daughters. A X-linked dominant gene fails to be transmitted to any son from a mother which did not exhibit the trait itself. Human Disorders In humans, X-linked dominant conditions are relatively rare....
Antibiotic resistance, loss of susceptibility of bacteria to the killing (bacteriocidal) or growth-inhibiting (bacteriostatic) properties of an antibiotic agent. When a resistant strain of bacteria is the dominant strain in an infection, the infection ma
Autosomes in Humans Human autosomes, the non-sex human chromosomes, are integral components of the human genome. Consisting of 22 pairs, autosomes carry a wealth of genetic information that governs numerous biological processes. These chromosomes play a pivotal role in various aspects of human devel...
1. Formation of Human Zygote (animal zygote) Fertilization is internal in humans i.e. zygote is formed and developed inside the body of a female in a fallopian tube. During sexual intercourse, millions of sperms are ejaculated and about a few hundreds of them will reach the ovum in the ...
An example of a successful hostile takeover is that of pharmaceutical company Sanofi's (SNY) acquisition of Genzyme. Genzyme produced drugs for the treatment of rare genetic disorders, and Sanofi saw the company as a means to expand into a niche industry and broaden its product offering. After...
