Definetion: the scientific
study of heredity
Example: when you study
about heredity.
Definetion: The passing
of physical
characteristics
from parents to offspring.
Defineiton: Each specific
characteristic,
such as stem hieght or seed
color, is called a trait.
Example: If you have a nose
or eyes or anything
else like a certain parent
that than is a trait.
Examples: Plants grow different sizes.
Some plants produce green seeds while others produce yellow seeds.
Heredity happens when
offspring occurs.
Example: Secientists are
describing factors that control a trait.
If you look more like your
mom than you have
more traits from her.
Definition: hidden whenever
the dominant
allele is present.
Definetion: To describe
the factors
that control a trait.
Studying the heredity
Example: you can only see it when the dominant allele is present.
Definetion: An organism is the
offspring of
many generations that have the
same form of a trait.
Definetion: A new organism
begins to form when egg and sperm
cells join in the process called fertilization.
Example: when the
egg and
sperm cells join
The word gene is only used
for another word.
Recessive Allele
Defintion: the different
forms of a gene.
Example: Purebred pea plants
always come from tall parent
plants.
Before fertilization
in pea plants, pollen
must reach the pistil
of a pea.
Example: Traits that are
different.
Plants grow by traits.
Scientists study this when the dominant is present.
Definetion: one whoose trait always
shows up in the organism when the
allele is present.
This organism has different
alleles.
Example: this organisms
dominant allele
showed up when it was tested.
Definetion: an organism
has two different
alleles for a trait.
Example: If a plant has two different alleles for a trait than the plant is a hybrid.
People study dominant
Allele.
Alot of plants are
hybrids.
