BIOL 105: Inheritance
08 with 100% correct
answers (graded A+)
Allele - answer one of two or more variants of a gene that determines a
particular trait for a characteristic
Blending Inheritance - answer the theory is that the progeny inherits any
characteristic as the average of the parents' values of that characteristic.
Codominance - answer in a heterozygote, complete and simultaneous
expression of both alleles for the same characteristic
Continuous Trait - answer When the phenotype for a given trait can take on
any value between two extremes. Ex. Height.
Dihybrid Cross - answer the result of a cross between two true-breeding
parents that express different traits for two characteristics
Discrete Traits - answer are controlled by a small number of genes, often only
one. These genes typically have two alleles
Dominant - answer describes a trait that masks the expression of another
trait when both versions of the gene are present in an individual
Epistasis - answer an interaction between genes such that one gene masks
or interferes with the expression of another
, Genotype - answer the underlying genetic makeup, consisting of both
physically visible and non-expressed alleles, of an organism
Heterozygous - answer having two different alleles for a given gene on the
homologous chromosomes
Homozygote - answer having two identical alleles for a given gene on the
homologous chromosomes
Incomplete Dominance - answer in a heterozygote, expression of two
contrasting alleles such that the individual displays an intermediate
phenotype
Inheritance of acquired characters - answer traits present in parents are
modified, through use, and passed on to their offspring in the modified form
Linkage - answer a phenomenon in which alleles that are located in close
proximity to each other on the same chromosome are more likely to be
inherited together
Mendel's law of independent assortment - answer genes do not influence
each other with regard to sorting of alleles into gametes; every possible
combination of alleles is equally likely to occur
Mendel's law of segregation - answer paired unit factors (i.e., genes)
segregate equally into gametes such that offspring have an equal likelihood
of inheriting any combination of factors
Monohybrid Cross - answer the result of a cross between two true-breeding
parents that express different traits for only one characteristic
Multiple Alleles - answer three or more forms of a gene that code for a single
trait
