Lecture 18: Intro to Mendelian Genetics Flashcards
1
Q
What is a monohybrid cross
A
a genetic cross that focuses on the inheritance of a single trait controlled by one gene
2
Q
What is the ratio in the F2 generation for a monohybrid cross
A
3:1
3
Q
What will happen to the ratio of next generation if the test is done with heterozygous parents
A
1:1 ratio
4
Q
What is Mendel’s first law
A
Genes segregate at meiosis so that each gamete contains only one of the two possessed by the parent
5
Q
What is Mendel’s second law
A
Independent assortment
Alleles of different genes assort
independently during gamete formation
6
Q
What is the ratio of the F1 generation of a Dihybrid cross
A
9:3:3:1
