Companion animal unit 2 test review (directional term) Flashcards
one of two or more forms of a gene that can exist at a single location
Allele
composed of a single DNA double helix molecule
Chromosome
refers to a pair of alleles, both of which exert an effect on the phenotype when they are present together
Codominance
the specific combination of alleles that an individual possesses at one or more loci.
Genotype
the outward appearance of an individual with respect to one or more traits that is associated with some particular genotype
Phenotype
having two different alleles at a Particular locus
Heterozygous
having two identical alleles at a particular locus
Homozygous
refers to an allele that has no effect on the phenotype unless it is present in the homozygous condition
Recessive
refers to an allele that has the same effect on the phenotype whether it is present in the homozygous condition
Dominant
tool used for determining the possible genetics outcomes of the offspring of two parents
Punnett Square
body plane that divides the animal onto dorsal and vertical parts
frontal
body plane that divides the animals into “equal” right and left halves
Median
closer plane that divides the body into cranial and caudal parts
transverse
any body plane that is parallel to the radian plane
Sagittal
further from the surface/ close to bone
Deep
toward the tail of an animal
Caudal
towards the head of an animal
cranial
part of the limb closest to the body
Proximal
part of the limb furthest form the body
Distal
along the back or uppermost surface
Dorsal
along the belly surface
Ventral
front of the animal
Anterior
