Genetics 1
How many dominant alleles are needed for a particular trait to show up?
1
What characteristics was Mendel studying when he crossed the pea plants?
-stem height -
color (yellow pea pods and green pea pods)
What is the law of independent assortment?
Alleles separate from each other during gamete formation.
This is the study of heredity
Genetics
TT and tt are both examples of a
Homozygous
What is another word for heterozygous?
Hybrid
What is another word for purebred?
Homozygous
This occurs when egg and sperm join to make offspring.
Fertilization
This is an organism's genetic makeup.
Genotype
This is an organism's physical appearance.
Phenotype
What did Gregor Mendel cross-pollinate in his genetics experiments?
Pea Plants
An organism with 2 different alleles for a trait is called a
Heterozygous/Hybrid
This shows all of the possible outcomes of a genetic cross.
Punnett Square
This type of organism has 2 different alleles for a trait
Heterozygous
What happens when a recessive allele is paired up with a dominant allele?
Hidden
This is a number that describes how likely it is that an event will occur.
Probability
This type of organism has 2 dominant alleles for a trait.
Homozygous Dominant
If a white flower and red flower are crossed, what color would the offspring be in incomplete dominance
Pink...due to blending of the traits because of incomplete dominance in flower colors.
This occurs when 2 traits are neither dominant nor recessive, both show up.
Co-Dominant
This type of organism has 2 recessive alleles for a trait
Homozygous Recessive
This is the passing of physical characteristics from parent to offspring.
Heredity
This was the scientist who first began studying heredity and genetics.
Gregor Mendel
Different forms of a gene.
Alleles
Neither trait is dominant over the other and the two blend together.
Incomplete Dominance
Factors that control traits are called.....
Genes
