Genetics Flashcards
What is true breeding
They produce offspring identical to themselves
What is genetics
The study of heredity, how characteristics are passed from one generation to another
What is a monohybrid cross
Looks at one tait at a time
What are genes
Two factors that control each trait
What is an allele
Genes that can be expressed in different forms
What is the principle of segregation
Parents can pass on at random only one allele for each trait to the offspring in their gametes
What is the principle of dominance
Of the two alleles, one will be dominant over the other
Dominant traits are expressed even if only one of the alleles is dominant
What is the purpose of a test cross (punnett squares)
To determine if a dominant genotype is homozygous or heterozygous dominant
