The organism will receive two letter symbols for each trait, one from each parent, these letter symbols make up the organsims ________ for that trait
The outward appearance of an organism is its ________
The phenotype is determined by the genotype, so an organism with a genotype of Gg would have a phenotype of _____ pods.
When both alleles of a pair are alike the organism is said to be homozygous for that characteristic. An organism may be homozygous ________ or homozygous _________
_________ is the likelihood that a specific event will occur.
Probability may be expressed as a decimal, _________, fraction, or a ratio
A cross between individuals involving a single pair of __________ traits is called a monohybrid cross.
Scientists use a tool called a ______ square to aid in predicting the probability of heredity patterns.
A homozygous; homozygous cross always predicts 100% probability that the offspring will be a certain genotype and phenotype. Thus there is a __% probability that the offspring will be a certain genotype and phenotype.
A homozygous; heterozygous cross will always predict a 50% 50% genotypic mix. The ________ mix will be dependent on what was crossed.
A heterozygous; heterozygous cross will always predict a 75% 25% __________ mix.
The ____ of the genotypes that appear in offspring is called the genotypic ratio.
The ratio of the phenotypes that appear in ________ is called the phenotypic ratio.
A ____ _____ is used when an individual of unknown genotype is mated to a homozygous recessive individual, the offspring are then compared to predicted values of known genotypes to determine the genotype of the unknown.
_________ dominancer occurs when there is no dominant phenotype and in the hererozygous condition both alleles are expressed in a blended phenotype.
In _________ both alleles are active and expressed. In this instance the alleles are not blended but are individually expressed, so you may end up with an organism that has two disticts colors of fur that appear as one color.
A ________ cross is a cross between two individuals where two pairs of contrasting tratits are compared.
