The passing of traits from parents to offspring is called
heredity
The scientist known as the “Father of Genetics” is
Gregor Mendel
Mendel conducted most of his experiments using
Pea Plants
Mendel controlled reproduction in his experiments through
pollination
Pollination that occurs within the same plant is called
self-pollination
Pollination between two different plants is called
cross-pollination
A trait that masks another trait is called
dominant
A trait that can be hidden by another trait is called
recessive
The physical appearance of a trait is called the
phenotype
The genetic makeup of an organism is called the
genotype
Different forms of the same gene are called
alleles
Structures that carry genetic information in the nucleus are called
chromosomes
When two alleles are the same (RR or rr), the genotype is
homozygous
When two alleles are different (Rr), the genotype is
heterozygous
In incomplete dominance, the offspring phenotype i
a blend of both parents
In codominance, the offspring phenotype
shows both traits equally
Traits controlled by more than one gene are called
polygenic
T or F: A genotype determines an organism’s phenotype.
T
T or F: Polygenic inheritance involves only one gene.
F
TT and tt would be?
Homozygous
Tt would be?
Heterozygous
White plants (WW) and red plants (RR) show incomplete dominance to create what color plants with what alleles?
Pink, RW
If white plants (WW) and red plants (RR) show codominance, what would their offspring look like?
The white and the red would both show up at the same time.
If a tall plant (T) and a short plant (t) have an offspring, and you have the following: TT, Tt, Tt, and tt, what percentage would be tall?
75%
Why did Gregor Mendel cross-pollinate?
Because he was able to see exact traits due to him pollinating the plants himself.
