________ is the measure of the likeliness that an event will occur.[1] ________ is quantified as a number between 0 and 1 (where 0 indicates impossibility and 1 indicates certainty).
A family tree describing the occurrence of heritable characters in parents and offspring across as many generations as possible.
monohybrid cross
A cross between parents differing with respect to a single specified pair of allele pairs.
Punnet Square
Squares used to find the probability of gene crosses. There are different kinds like mono, di.
F2 Generation
Progeny produced by intercrossing or self fertilization of the F1 individuals.
The study and analysis of heredity and variation.
Is the process that all living things reproduce themselves and transfer physical characteristics to the next generation.
Test Cross
The individual having the dominant phenotype is crossed with one having the recessive phenotype.
The resemblances and differences between individuals of the same or different generations.
An _____ is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome.
Observed expression of an organism
Law of segregation
Alternative forms are encoded by discrete alleles, each gamete has an equal chance of getting either allele.
Is made up of the sum total of all the character determinants. Genetic constitution of an organism.
A line of descent whose member carry the same genotype.
The progeny of a cross between genetically unlike parents.
Law of Independent Assortment
Genes located on different chromosomes assort independently of one another.
Relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents.
When two members of an allele pair are alike, individual is _______ for these alleles.
When two members of a given allele pair are unlike.
In genetics, a trait that will appear in the offspring if one of the parents contributes it.
P1 Generation
The parental generation with which the genetic experiment starts.
F1 Generation
First filial (latin word for son) generation.
Self Pollination
Pollen is transferred from the anther to the stigma of the same flower. Such flowers are hermaphrodites, which have both sexes. In Type II pollen is transferred from the anther of one flower to the stigma of another flower from the same plant.
