What diseases are inherited by boys?

There are many diseases in life that are passed down from father to son and not from father to daughter. Others occur specifically in boys or girls. In fact, most of the genes for these genetic diseases determine the memory of the children. The genes of boys and girls are different, so the chances of inheritance are naturally different. Let us take a look at the relevant introduction to genetic diseases below.

What is Genetics

Heredity refers to the transmission of genes so that offspring acquire the characteristics of their parents. Genetics is the discipline that studies this phenomenon. It is currently known that existing life on Earth mainly uses DNA as genetic material. In addition to genetics, other factors that determine biological characteristics include the environment and the interaction between environment and genetics.

Genetic diseases

Genetic diseases refer to diseases caused by changes in genetic material or controlled by pathogenic genes. Genetic diseases refer to diseases that are completely or partially determined by genetic factors. They are often congenital but can also be acquired. Such as congenital idiocy, polydactyly, congenital deaf-muteness, hemophilia, etc. These genetic diseases are completely determined by genetic factors and will only occur after a certain period of time after birth. Sometimes it takes several years, more than ten years or even decades before obvious symptoms appear.

Genetics

Genetics - the science that studies the inheritance and variation of organisms, and the discipline that studies the structure, function, variation, transmission and expression of genes. The concept of parent-child in genetics is not limited to parents and children or one family, but can also be extended to groups including many families, which is the research object of population genetics. The concept of parent-child in genetics can also be based on cells. Cells cultured in vitro can maintain some genetic characteristics of the individual, such as the presence or absence of certain enzymes. The genetic study of cells cultured in vitro belongs to somatic cell genetics. The concept of parent-child in genetics can also be expanded to the replication of DNA and even the transcription of mRNA, which are topics of molecular genetics research.

Research Scope

The research scope of genetics includes three aspects: the nature of genetic material, the transmission of genetic material and the realization of genetic information. The nature of genetic material includes its chemical nature, the genetic information it contains, its structure, organization and changes; the transmission of genetic material includes the replication of genetic material, the behavior of chromosomes, genetic laws and the quantitative changes of genes in a population; the realization of genetic information includes the original function of genes, the interaction of genes, the regulation of gene action and the mechanism of action of genes in individual development.

Genetic abnormalities

Abnormalities in one or more genes, especially recessive genes, are quite common. Each person carries 6 to 8 abnormal recessive genes. However, these genes do not cause abnormal cell function unless two similar recessive genes are present. In the general population, the probability of an individual having two similar recessive genes is very small, but in children of close relatives, this probability is higher. The rate is also higher in groups that practice close-kin marriage, such as the Amish Christian Amish.

A person's genetic makeup is called their genotype. The reflection of the presence of these genes in the human body, that is, the expression of the genotype is called the phenotype.
