Inbreeding has the effect of maintaining genetic defects in the bloodline. For example some human populations are descended from a limited genetic stock and have a high incidence of particular types of cancer and other diseases carried by defective genes, such as hemophilia, sickle-cell anemia and cystic fibrosis.
If anyone in the family has a health problem the children would be more likely to get it. If anyone had a harelip or other deformity the children might inherit it.
inbreeding= the act of of mating genetically within the same genetic pool (close relations) Mating with 1st cousins does contribute to inbreeding and can be OK but often presents genetic problems, which is far less likely with 2nd cousins to the point where it is basically OK to marry a 2nd cousin. Some 1st cousins can and do marry and everything is fine, especially with genetic testing prior to having kids. In many small towns throughout history cousins tended to end up married here and there- the worst problems come from repeated marrying of 1st cousins over and over within a small community or family. This has affected royal families since they could only marry other royals- at times anemia, retardation, and genetic diseases have plagued royal families until they realized the need to bring in some new blood.
Inbreeding can cause some risk such as blindness or joint deformities in animals.
BREEDING
Inbreeding is a selective breeding method in which 2 individuals with identical or similar sets of alleles are crossed.
Inbreeding
Yes. Even first cousins will usually have normal and healthy children. No one worries about fifth cousins having children together, unless there has been lots of closer inbreeding in their families in previous generations.
There are some people in the Ozark mountains who have married 5th cousins. In fact, it is quite common in many places. The closest to inbreeding occurs in the Arab world where marriage between first cousins is common. Historically, the closest inbreeding occurred among Egyptian, Incan, and Polynesian royalty where a brother would marry a sister.
There's a very slight risk of inbreeding, but it's really not as bad as most people think. In many cultures, first cousins are regarded as ideal mates.
Your first cousins childrens are your second cousins.
Not f*cking your cousins will definitely reduce the likelihood of homozygous recessive allele expression, thus effectively eliminating the damaging effects of inbreeding.
Your father's first cousins are your first cousins, once removed.
You would have a variety of different relationships to the cousins of your first cousins. Some of them are you and your siblings, and some of them are also your first cousins. Second cousins of your first cousins may also be your second cousins. In addition, your first cousins will have many cousins who are not related to you at all. You are lreated to your first cousins because each of you have one paret who is a sibling of one parent of the other. But each of you also has one other parent, who also has siblings and the children of those siblings are cousins to one of you but not to both.
Your Father's first cousins are also your first cousins, once removed.
second cousins or first cousins once removed
Hi, Ciara and T.i are cousins, full blood first cousins. Hi, Ciara and T.i are cousins, full blood first cousins.
Your uncle's first cousins are also your parent's first cousins and so are your first cousins once removed. Similarly his second cousins are your second cousins once removed.
The children of your mother's first cousins are your second cousins. The children of your mother's second cousins are your third cousins. The children of your mother's third cousins are your fourth cousins. And so forth.
