a model that predicts the likely outcomes of a genetic cross
A Punnett square shows all of the _______ that could result from a given cross
A simple Punnett square can be used to analyze a _________ cross
Monohybrid Homozygous Crosses
cross between two homozygous plants
YY x yy=Yy
Monohybrid Heterozygous Crosses
Predicts the results of a monohybrid cross between two heterozygous genotypes
What is the genotypic ratio of a monohybrid heterozygous cross?
1 YY: 2 Yy: 1 yy
What is the phenotypic ratio of a monohybrid heterozygous cross?
3 yellow: 1 green
________ is the likelihood that a specific event will occur
Law of segregation states that each gamete has an _____ chance of receiving either _ of the two alleles
a family history that shows how a trait is inherited over several generations
A simple way to model inheritance is to use a _______
A healthcare worker may use a ______ to help a family understand a _______ ________
pedigree, genetic disorder
A pedigree can help answer questions about what 3 aspects of inheritance?
sex linkage, dominance, heterozygosity
A sex linked gene is located on either the _ or _ chromosome, but most are located on the _ chromosome
X, Y, X
If a person has a trait that is autosomal and dominant and has even one dominant allele, they (will/will not) show the trait
If a person has a recessive trait and only one recessive allele, he or she (will/will not) show the trait, but may pass it on
