Vocab
“+”
The initial phenotype of a trait in nature, gets matured into other traits.
Wild Type
An organizations underlying genetic makeup. Consisting of physically visible and non-expressed alleles.
Genotype
A fatal genetic disorder causing the progressive breakdown of nerve cells in the brain
-this will likely be a genetic problem-
Huntingtons disease
“Recombination”
it is possible for two genes on the same chromosome to behave independently or as if they were not linked.
Crossing over
A paired cross in which the respective traits of a couple in one cross become the respective traits for a couple in another cross.
Reciprocal cross
two discrete copies of characteristics that are passed individually to offspring.
Genes
-variation of incomplete dominance-
both alleles for the same characteristic are simultaneously expressed in the heterozygote.
Codomininece
Range off small differences between individuals
ex: height
Continuous variation
Matching two true-breeding individuals that have different traits
Hybridization
A variation in the physical appearance of heritable characteristic.
Trait
A form of inheritance where one allele does not completely mask the other. Resulting in a heterozygous phenotype that is a blend or intermediate of the two homozygous traits.
Incomplete dominance
Gender most effected by X-linked traits.
Males
Segregation of alleles into gametes can be influenced by ____?
Genes that are located physically close to one another on the same chromosome are more likely to be inherited as a pair.
Linkage
Gene variations that arise by mutations and exists at the same realistic locations on homologous chromosomes.
Alleles
Used to predict all possible outcomes of all random fertilization events and their expected frequencys.
Punnet Squares
Seen when one person shows one of two or one of a few characteristic
ex: white flowers
Discontinuous variation
Only have one allele for any X-linked characteristic; most prominently in males.
Hemizygous
Observable traits expressed by an organism.
Phenotype
An inherited genetic disorder, primarily effecting males, that prevents blood from clotting due to low levels of clotting factors.
X-linked genetic disorders caused by mutations in f8
Hemophilia
The interactions between genes is antagonistic, such as that one masks or interferes with the expression of another.
Epistasis
