Unit 11: Intro To Genetics Flashcards
Cross pollination
Two genetically different parent plants
Offspring known as hybrid
Sexual reproduction
Gregor Mendel
“Father of genetics”
Studied pea plants
P Generation
Original pair of parents
F1 Generation
First offspring of the P generation
F2 Generation
Offspring of F1 generation
Alleles
Different expressions of a gene
Tall vs short
Green vs yellow
Dominant trait
Shows up even if paired with a recessive allele
Capital letter
Recessive trait
Masked if paired with dominant allele
Expressed if paired with another recessive
Lowercase letter
Hybrid
Organism with two different alleles for a single trait (eg Tt)
The Law of Segregation
During gamete formation, alleles for each gene separate into sperm and egg so that each carries one allele
