The Father of Genetics
He is known as the "Father of Modern Genetics" for his work with pea plants.
Who is Gregor Mendel?
This is the study of heredity and the transmission of characteristics from parents to offspring.
What is Genetics?
This diagram is used to predict and compare the genetic variations that will result from a cross.
What is a Punnett square?
In this pattern, the heterozygous phenotype is a blend between the two homozygous phenotypes.
What is incomplete dominance?
This is the term for a cross that follows just one specific trait.
What is a monohybrid cross?
Mendel used these specific organisms to discover the basic principles of heredity.
What are pea plants?
The human genome is made up of this many total chromosomes.
What is 46?
This term describes an organism that has two identical alleles for a particular gene.
What is homozygous?
This occurs when both alleles contribute to the phenotype, like a chicken with both black and white feathers.
What is codominance?
This is the term for a cross that examines two different traits at the same time.
What is a dihybrid cross?
This Mendelian principle states that some alleles can mask the expression of others.
What is the Principle of Dominance?
These are the specific regions of a chromosome that code for proteins and determine traits.
What are genes?
This term refers to the physical characteristics or appearance of an organism.
What is a phenotype?
Traits like human blood type are controlled by more than two versions of a gene, a pattern known as this.
What are multiple alleles?
These are specialized cells, like eggs or sperm, that carry only a single copy of each gene.
What are gametes?
This law explains that the two alleles for a trait separate during gamete formation so each reproductive cell carries only one copy.
What is the Law of Segregation?
hese are alternate forms of the same gene.
What are alleles?
This is the genetic makeup or allele combination of an organism, such as Tt or RR.
What is a genotype?
Traits controlled by the interaction of two or more genes, like skin color or height, are called this.
What are polygenic traits?
Scientists use this type of cross to determine if an organism with a dominant phenotype is homozygous or heterozygous.
What is a test-cross?
This generation of plants is the first offspring produced from a cross of two parent plants.
What is the F1 generation?
Humans inherit exactly this many chromosomes from each individual parent.
What is 23?
These mathematical principles are used to predict the likelihood of certain outcomes in genetic crosses.
What is probability?
This principle states that genes for different traits segregate independently during gamete formation.
What is independent assortment?
his term describes organisms that, if allowed to self-pollinate, would produce offspring identical to themselves.
What is true-breeding?
