Genetics
The scientist responsible for the study of heredity, aka genetics.
Who is Gregor Mendel?
Mendel principle that states alleles separate during the formation of gametes.
What is the Principle of Segregation?
Skin color is an example of this mode of inheritance.
What is multiple alleles?
Red carnations are crossed with White carnations. The probability of pink carnations in the offspring.
What is 100%?
The cell that is made by the process of meiosis.
What is a gamete?
The unit of heredity as identified by Mendel.
What is an allele?
Test subject used by Mendel to develop the principles of genetics.
What is a pea plant?
Two dominant alleles are present and they mix in offspring.
What is Incomplete Dominance?
A pea with homozygous dominant green seeds is crossed with a pea producing homozygous recessive yellow seeds. The probability of the offspring having yellow seeds.
What is 0%?
The name of the name of a cell with a full set of chromosomes.
What is diploid?
The number of alleles that were responsible for a trait according to Mendel.
What is 2?
Name for a genotype composed of the same type of allele.
What is homozygous, or pure?
In the presence of the dominant allele the recessive allele is hidden, or masked.
What is Mendelian Dominance?
A person with heterozygous type B blood is crossed with a person having heterozygous type A blood. The probability of offspring with type O blood.
What is 25%?
The process of exchanging parts of chromatids in a tetrad that results in tremendous genetic diversity for sexually reproducing organisms.
What is "crossing over"?
The representation of the genetic make up of a trait.
What is a genotype?
Principle that explains why eye color and hair color are not passed from parent to offspring in pairs.
What is the Principle of Independent Assortment?
Codominance occurs when 2 dominant alleles are present for the trait and both are expressed in the phenotype. An example would be
What are human blood types?
A person is heterozygous for six fingers is crossed with someone else that has 5. The probability of the baby having 5 fingers.
What is 50%?
What is 19?
The name for the expression of the physical characteristic.
What is a phenotype?
Mendel found that this was the dominant allele for plant height.
What is tall?
A trait controlled by more than one gene.
What is a polygenic trait?
White carnations are crossed with Pink carnations. The probability of White carnations in the offspring.
What is 50%
The phase, or lack thereof, that is most important for getting the diploid cell to four haploid cells.
What is the lack of Interphase II?
