TT or tt are examples of heterozygous or homozygous?
What is the homozygous genotype for tallness (T)?
cross of two of two individuals that involves one pair alleles for a single trait
law of independent assortment
inheritance of one trait has no affect on the inheritance of another
example of somatic cell mutation
mutations that occurs when a piece of chromosome breaks off and reattaches
if characteristic on Y-linked it occurs in
traits influenced by genes and environment
traits controlled by 2 or more genes
example of sex-influenced trait
male pattern baldness
occurs when phenotype of the heterozygous is an intermediate form between dominant and recessive (Roan Cow)
when pollination occurs with two different plants
Both alleles are expressed in the heterozygous condition.
cross with individual of unknown genotype is grossed with homozygous recessive individual
describes organisms which produce offspring with a desired trait
two different alleles in a pair
probability of offspring of homozygous dominant crossed with homozygous recessive individual will exhibit the dominant phenotype
A genetic trait that appears in every generation of offspring is called
inheritance of one trait does not affect the inheritance of another
law of independent assortment.
