Lesson 7 - Dihybrid Crossing Flashcards
1
Q
Mendel’s experiment for the inheritance of two traits
A
he crossed true breeding plants that produced yellow round seeds with true breeding plants that produced green wrinkled seeds, the peas in F1 gen all displayed the dominant trait for both traits, the F2 gen had a mix of four phenotypes but came to a close 9:3:3:1 ratio,
2
Q
law of independent assortment
A
he found the 9:3:3:1 ratio for all dihybrid crosses, this only happens if the inheritance of one trait has no influence on the inheritance of another
3
Q
chromosome theory
A
during gamete formation alleles segregate just as homologous chromosomes do and proposed that genes are carried on chromosomes
