When there is a dominant trait and a recessive trait the dominant trait is always showing but there is still the recessive trait hidden. The dominant trait also shows when there are two dominant traits. When there are two recessive traits the recessive trait is showing.
When there is co-dominant traits there are two alleles where neither is dominant nor recessive. Traits are controlled by dominant alleles. For example AB is co-dominance.
Each parent (mother and father) give the offspring 23 chromosomes. A human has 46 chromosomes but a human’s germ cells or sex cells have half. So the parents of any offspring give half their chromosomes to their offspring giving the offspring a total amount of chromosomes.
The project was launched in 1990. The main goal of the Human Genome Project is to identify the DNA sequence of every gene in the human genome. A genome is all the DNA in one cell of an organism. With the information from the human genome project researches will gain a better understanding of how humans develop from a fertilized egg to an adult. They may also learn what makes the body work and what makes things go wrong. New understandings can seek out genetic diseases before hand, for prevention basically.
With the human genome project scientists have been able to let people know there DNA sequence which lets you know every genetic disorder or disease that you may have or express. The problem with this is that scientists aren’t sure if you will ever experience the disorder or disease; there is still a 25% change you won’t get it. Knowing what you may experience before it happens can put people on edge and may change there life as they know it because they are afraid they might get the disorder or disease.
Created laws because people were getting information about genetic information. They made GINA which keeps test results private so there will be no discriminating.
A single-gene disorder is a heredity disorder caused by a mutant allele of a single-gene.
Hemophilia, Sickle-cell disease and Color Blindness are two single- gene disorders.
A chromosome abnormality is where a person’s chromosomes are unusual.
Some chromosome abnormalities are Turner syndrome which is where a women only has a X chromosome and is missing the other X, Klinefelter’s syndrome is when a male has XXy, that means they have male and female reproductive parts and Down syndrome is where there are too many or too few chromosomes.
Genetic counseling gives parents whose children might be born with genetic diseases information before or during a pregnancy to them make decisions about their child.
There are many pros and cons for designer babies. Some dislike the idea while others think it’s a good idea to use genetics and the technology we have now a day for a perfect child. In order to make the child you would have to alter the chromosomes, there are defects that may happen that will harm the mother and/or child. The procedure although risky can have many good outcomes like the child can have any attitude of physical traits you want it to have. The procedure costs around $18,000. Parents worry daily that there child will become sick, but with designer babies you only have to pay for the procedure and then your baby is normally healthy for the rest of its life there for you don’t have to pay the extra money for yearly check-ups or medical issues. Also if you have a type of cancer with this procedure you can alter your babies chromosomes so that they won’t have it.
