Which of the Following Can Be Seen as an Indication That Intelligence Has a Strong Genetic Basis
What Is Genetics?
Genetics is the report ofgenes. Our genes comport information that gets passed from one generation to the next. For case, genes are why one child has blonde pilus like their mother, while their sibling has brown hair similar their male parent. Genes also determine why some illnesses run in families and whether babies will be male or female person.
What Are Genes?
Genes are sections ofDna (deoxyribonucleic acid) that are constitute inside every man cell. They're so tiny that they can be seen only under a powerful microscope. DNA is fabricated of four chemicals that form pairs in dissimilar combinations. The combinations create codes for different genes. Each person has near twenty,000 genes. The genes code for different traits, such every bit eye color, body type, or male or female sex.
What Is a Chromosome?
Inside each prison cell, Dna is tightly wrapped together in structures calledchromosomes. Every normal cell has 23 pairs of (for a total of 46):
- 22 pairs of chromosomes are the aforementioned in males and females. These are called autosomes (pronounced: AW-tuh-soamz).
- The 23rd pair — the sex chromosomes — determines the sexual practice of the baby. Females accept two X chromosomes and males have one X chromosome and 1 Y chromosome.
How Do Genes Laissez passer From Parent to Child?
To course a fetus, an egg from the female parent and sperm from the father come together. The egg and sperm each have one one-half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. That's how we can inherit some things from our mother and some from our begetter.
What Is a Genetic Disorder?
A genetic disorder happens when a gene (or genes) has a problem with its code, and this causes a health problem. Sometimes a genetic disorder happens when a child inherits it from ane or both parents. Other times, it happens only in the child (and the parents exercise non accept the genetic disorder).
How Do Genetic Disorders Happen?
Unlike things tin cause a genetic disorder, such as:
- a change (mutation) in one gene on a chromosome
- a missing part of a chromosome (chosen a deletion)
- genes shifting from one chromosome to another (called a translocation)
- an extra or missing chromosome
- too few or besides many sex chromosomes
Looking Ahead
Scientists are learning more and more about genetics. A worldwide enquiry project called The Homo Genome Projection created a map of all homo genes. It shows where the genes are located on the chromosomes. Doctors tin use this map to find and treat or cure some kinds of genetic disorders. There is hope that treatments for many genetic disorders will be developed in the future.
