Chapter 12: Genetics Crossword

genes do not influence each other with regard to sorting of alleles into gametes; every possible combination of alleles is equally likely to occur
having two different alleles for a given gene on the homologous chromosome
in a heterozygote, complete and simultaneous expression of both alleles for the same characteristic
gene variations that arise by mutation and exist at the same relative locations on homologous chromosomes
visual representation of a cross between two individuals in which the gametes of each individual are denoted along the top and side of a grid, respectively, and the possible zygotic genotypes are recombined at each box in the grid
trait that appears “latent” or non-expressed when the individual also carries a dominant trait for that same characteristic; when present as two identical copies, the recessive trait is expressed
observable traits expressed by an organism
variation in the physical appearance of a heritable characteristic
having two identical alleles for a given gene on the homologous chromosome
results of a cross between two true-breeding parents that express different traits for only one characteristic
result of a cross between two true-breeding parents that express different traits for two characteristics
any of the non-sex chromosomes
trait which confers the same physical appearance whether an individual has two copies of the trait or one copy of the dominant trait and one copy of the recessive trait
underlying genetic makeup, consisting of both physically visible and non-expressed alleles, of an organism
phenomenon in which alleles that are located in close proximity to each other on the same chromosome are more likely to be inherited together
An organized visual profile of the chromosomes in the nucleus of a body cell of an organism.
