the passing of traits from parents to offspring
the different forms of a gene
the study of how traits are inherited through the actions of alleles
He was a monk who was born in Austria in 1822. He experimented with pea plants. He is known as the "Father of Genetics".
an organism that always produces the same traits in its offspring
a factor that covers up a recessive factor; tall is dominant to short
a factor that is covered up by a dominant factor
a handy chart that predicts genetic results
the genetic make-up of an organism
the two alleles for an organism are exactly the same (TT or tt). This is also known as Purebred..
the two aleles for an organism are different (Tt or Nn). This is also known as Hybrid.
The physical trait that shows as a result of a genotype. (TT = tall; Tt = tall; tt = short; YY = yellow; yy = white))
the phenotype resulting in a "blended" result; red and white flowers producing a PINK flower, not just only red or white flowers.
when a gene undergoes a change that results in a trait that is expressed differently
some causes of mutations
chemicals, x-rays, and radioactive substances
when either too many chromosomes or too few chromosomes are inherited by an offspring
recessive genetic disorders
these genetic disorders occur when both parents have a recessive allele for a disorder; the parents my be heterozygous and not show any symptoms of a disorder, but if the child inherits a recessive gene from each parent, then the child will have ta recessive genetic disorder like cystic fibrosis.
The female only provides an X chromosome, but the male may fertilize an egg with either an X or Y. If an X fertilizes the egg, then XX or a girl will result. If a Y fertilized the egg, then XY or a boy will result.
some allele are on the sex chromosomes like color-blindness, which is sexlinked on the X chromosome.
it is a visual tool for following traits through generations of a family
experimenting with biological and chemical methods to change the arrangement of DNA that makes up a gene
inserting a useful segment of DNA from one organism into a bacterium; an example is the production of growth hormone to treat dwarfism and chemicals to treat cancer
replacing abnormal genetic material with normal genetic material
Alternate forms of a gene are called _____________.
The outward appearance of a trait is a ______________.
Human height, eye color, and skin color are all traits controlled by _____________.
The science that deals with the study of heridity is _____________.
The actual combination of alleles of an organism is its ________________.
The moving of fragments of DNA from one organism and inserting them into another organism is ____________.
The helpful device for predicting the probabilities of possible genotype is called a ______ ______________.
The passing of traits from parents to offspring is called ______________.
Red-green color blindness is a numan genetic disorder caused by a ____________.
What controls traits in organisms?
What term describes the inyheritance of cystic fibrosis?
What describes the allele that causes color blindness?
it is carried on the X chromosome
