the science that studies how traits are inherited through the interactions of alleles
heredity
genetics
biology
the passing of traits from parent to offsprint
heredity
genetics
botany
the physical or visible appearance of an organism; a trait we can see
genotype
phenotype
blue eyes, curly hair
genotype
phenotype
Tt, BB, rr
genotype
phenotype
controls the trait; you only need one gene for the trait to show up in an organism
dominant
recessive
the weaker trait; you need 2 genes for the trait to show up in an organism
dominant
recessive
the different forms of a trait that make up a gene, R OR r
allele
dominant
recessive
purebred; the same gene pair (Alleles)
homozygous
heterozygous
hybrid; a different gene pair (Alleles)
homozygous
heterozygous
TT, tt

the father of genetics
James Watson
Robert Hooke
Gregor Mendel
Reginald Punnett
a tool used to predict the results from crossing 2 sets of allelles
microscope
Punnett square
Jawsome trapezoid
The basic unit of heredity that consists of a segment of DNA on a chromosome
chromosome
double helix
homozygous
gene
An organism that inherits two of the same alleles from its parents
dominant
phenotype
heterozygous
homozygous
A term that describes an allele that is not expressed when combined with a dominant form of the allele
gene
recessive
homozygous
phenotype
The likelihood or chance that a specific outcome will occur out of a total number of outcomes
heredity
probability
percentage
ratio
The passing of genes from parents to offspring
Punnett Square
probability
genetics
heredity
An organism that inherits two different alleles from its parents
dominant
recessive
homozygous
heterozygous
The trait expressed if you inherit Ff is the
genotype
dominant trait
recessive trait
homozygous
Which of these would express the dominant trait?
AA
Tt
Rr
All of the above
In order for a recessive trait to be expressed,
both alleles have to be recessive
one allele has to be recessive
one allele has to be recessive while the other is dominant
both alleles have to be expressed with capital letters
P refers to
Punnett squares
The parental generation
The percentage of offspring
a recessive allele
F1 refers to
The first dominant allele
The first offspring
The first filial generation from crossing the P generation
The second filial generation from crossing the F1 offspring
F2 refers to
The second dominant allele
The second offspring
The first filial generation from crossing the P generation
The second filial generation from crossing the F1 offspring
True or False: Phenotype is determined by genotype
True
False
