Which one is not a genetic disorder color blindness hemophilia cystic fibrosis down syndrome?
Down syndrome is a polyploidy (three chromosome 21s)and is considered to be a somatic disorder. The other three are genetic because they are present in the form of a defective allele on achromosome.
Describe three ways genetic diseases are caused?
1. (1) Produced by an abnormality in, or a mutation of the genetic code in a single gene; (2) Caused by several abnormal genes (Producing so-called polygenic diseases); or (3) Caused by the abnormal presence or absence of an entire chromosome or by alteration in the structure of chromosomes.
All organisms have a genetic code made of?
All organisms have a genetic code made of these three nucleotide sequences called codons.
What is a genetic wheel?
Because of four different bases, there are 64 possible three-base codons (4x4x4=64). the genetic wheel shows all 64 possible codons of the genetic code.
What is genetic engineering describe three possibilities benefits on this technique?
Genetic Engineering is the study and application of genetics for a better life/future. Genetic engineering can be used to produce medicines & to improve food crops. Researchers are also using genetic engineering to try to cure human genetic disorders.
When Having three copies of chromosomes 21 leads to a disorder known as trisomy 21 or more commonly as?
Down syndrome is trisomy 21
Which term is defined as all the genes in a person's twenty-three pairs of chromosomes?
Humans without a disorder will have 23 pairs of chromosomes. However, there are many disorders caused by different numbers of chromosomes. For example, Trisomy 21 (Down Syndrome) is a disorder caused by the presence of an extra chromosome 21.
What happen lack of chromosomes?
If there is a lack of chromosomes, then the full genetic structure of a human being cannot be reproduced because a human is made up of forty-three chromosomes (twenty-three from each parent) and if one is missing, there will only be forty-five, which will not reproduce a human being.

What is three copies of chromosomes known as?
Three copies of chromosomes are known as trisomy. This genetic condition can result in disorders such as Down syndrome (trisomy 21) when an individual has an extra copy of chromosome 21.
What are the three outcomes of meiosis?
The three outcomes of meiosis are genetic diversity through crossing over, haploid cells with half the number of chromosomes as the parent cell, and the formation of four genetically unique daughter cells after two rounds of cell division.
How many chromosomes are in 1 pair of chromosomes?
There are 46 chromosomes (condensed threads of genetic material formed from chromatin as a cell prepares to divide), and 23 pairs of chromosomes in the human body.
How many chromosome does a gamete contain?
there are 23 chromosomes in a human gamete
How does triple x syndrome occur?
Triple X syndrome is a genetic disorder in which a girl has three X chromosomes instead of two. Triple X occurs once in every 1,000 female births. However, doctors believe many girls with Triple X go their lifetime undiagnosed. The major features of Triple X are learning, behavioral and emotional problems. Compared with other syndromes in which a person has inherited three chromosomes. Triple X is quite mild in nature.
What are the 3 sources of genetic recombination?
Genetic recombination refers to the process by which two DNA molecules exchange genetic information. The three types of genetic recombination are crossing over, conservative site-specific recombination and transpositional recombination.
How many chromazones do fruit flys have?
They have 4 pairs ofchromosomes not chromazones. one sex chromosome and three autosomes.
What happens if you have more than one chromosomes?
Individuals with additional chromosomes beyond the normal 2N complement are generally nonviable and the few exceptions that result in a live offspring are still profoundly affected in a negative way. he presence of additional sex chromosomes often have less profound effects.
