Dominance
An allele is said to be this when it masks the effects of the other allele
dominant
The Study of Heredity
What is Genetics
When the two alleles are the same
homozygous
The tool/chart that is used to examine crosses
Punnett Squares
traits that are passed on from parent to offspring are said to be ____ and not acquired
inherited
T
The father of genetics
Who is Gregor Mendel
the t in Tt is this type of allele. You must have two of this type of allele for it to be expressed
recessive
25%
A Sun tan is an example of this type of trait
A type of dominance where both alleles are fully and independently expressed
What is Codominace
One of a number of different forms of a gene
When the two alleles are different
Heterozygous
the mating of two organisms to observe the resulting genotypes and phenotypes
cross
the likelihood of a certain trait occurring in an organism
What is probability
This is when you have 2 alleles and one codes for red flowers and the other for white and you actually get pink flowers
Incomplete Dominance
The passing on of characteristics from one generation to the next
what is heredity
tt is a recessive example of this type of allele pairing
homozygous
the probability that you get a recessive phenotype from this cross: tt x tt
100%
The genotype dictates this, it is the physical expression of the organism
phenotype
This is when the heterozygous phenotype is a blend of the two homozygous phenotypes
What is Incomplete dominance
The actual Genetic make-up of an organism (TT Tt tt)
What is genotype
The allele that always wins when it is present
dominant allele
LL x ll results in 100% probability of this genotype
Ll
The type of plant that Gregor Mendel studied
Pea Plant
