Genetics
the scientific study of heredity
Genetics
Inheritance is...
one of two or more forms that a gene could take
Alleles
A molecule found in the cell nucleus that encodes genetic information
DNA
a scientist who studies heredity
Geneticist
A segment of DNA that determines or helps to determine a trait
Genes
a pattern of inheritance in which phenotypes of both alleles inherited for a trait are clearly expressed
Codominance
An allele that is always expressed when it is present
Dominant Allele
the genetic makeup of an organism
Genotype
The transfer of genetic information from one generation to the next
Reproduction
The rod shaped structures found in the nucleus of every cell in a organism
Chromosome
the passage of genetic information from a parent or parents to a offspring
Heredity
An allele that is not expressed when the dominant allele is present (Lowercase such as t).
Recessive Allele
The likelihood that something will occur
The trace remains of an organism that lived long ago, commonly persevered in sedimentary rock.
Fossils
A trait is..
A characteristic of an organism
a diagram that shows the possible offspring of two parents
Punnet Square
A condition when neither of the two genes in a gene pair mask another.
Incomplete dominance.
A single time experiment is conducted
Trial
Changes in species that occur through gradual processes over many generations.
Diversity of Life
The father of genetics
Gregor Mendel
A phenotype is...
the physical appearance of an organism
The difference between homozygous and heterozygous.
Homozygous is having two alleles that are the same while heterozygous is having two alleles that are different
A punnet square shows the probability of a pea coming out with smooth or wrinkled skin based on its parents. If the squares contain Rr, Rr,rr, and rr, what is the probability of it being a smooth plant
50%
Any different between individuals of the same species.
