science
how a trait appears or is expressed
phentotype
a different form of gene
allele
a type of asexual reproduction that occurs when an offspring grows from a piece of its parent.
regeneration
the way an organism reacts to other organisms or to its environment.
behavior
a genetic factor that is blocked by the presence of a dominant factor.
recessive
the passing of traits from parents to offspring.
hereditary
the alleles of all the genes on an organism’s chromosomes; controls an organisms phenotype.
genotype
a form of asexual reproduction in which offspring grow from a part of a parent plant.
vegetative reproduction
the process that occurs when pollen grains land on a female reproductive structure of a plant that is the same species as the pollen grains.
pollination
the study of how traits are passed from parents to offspring.
genetics
a genotype in which the two alleles of a gene are the same.
homozygous
a type of reproduction in which only one parent organism or part of that organism produces a new organism.
asexual reproduction
the growth of a plant toward or away from light.
phototropism
a genetic factor that blocks another genetic factor.
dominant
a genotype in which the two alleles of a gene are different.
heterozygous
a form of asexual reproduction where an organism grows on the body of its parent.
budding
the response of a plant to touch.
thigmotropism
a section of DNA on a chromosome that has genetic information for one trait.
gene
a model that shows genetic traits that were inherited by members of a family.
pedigree
type of reproduction where the genetic material from two different cells combine, producing an offspring.
sexual reproduction
the response of a plant to gravity.
gravitropism
