What inheritance pattern does this heterozygous individual demonstrate?
The heterozygous offspring has a phenotype showing each parent's phenotype
Gregor Mendel found that traits are....
What does true breeding mean?
Contain same allele for a trait
What does hybrid mean?
Offspring of two different true-breeding varieties.
Only requires one copy to express trait, appears to affect the trait
Requires two copies to express trait, doesn't appear to affect the trait
What is a genotype?
The alleles they carry for a trait
What is a phenotype?
The physical expression for the trait
Two different alleles for a trait
What is the parent (P) generation?
A cross between two homozygous parents, one homozygous dominant and the other homozygous recessive
What is the F1 generation?
The offspring of the parent generation, which will be all heterozygous individuals
What is the F2 generation?
Is the result of a cross of two heterozygous individuals. The offspring will be 1 homozygous recessive, 2 heterozygous, and 1 homozygous dominant
What is a testcross?
A cross of an unknown genotype with a homozygous recessive individual. This will reveal the genotype of the unknown.
Who is more effected by sex-linked traits?
Males, because they only inherit one x chromosome
