LA 5 Flashcards
what is true breeding
when the plants are allowed to self fertilise , producing offspiring with the same trait over generations
what is a monohybrid cross
a single character trait with two forms
a single gene with two alleles
when do we use the multiplication rule
to determine the probability of two independent events
what is thebadditon rule
the probability that any one of two or more mutually exclusive events will occur, we add their probabilities
if a 3:1 ratio is seen what does this usually mean
a single gene with two alleles
what is mendels first law
the law of segregation : alleles of a single gene segregate equally into gametes
what are dihybrid crosses
involve 2 different character traits. ratio normally 9 3 3 1
what is mendels second law
independent assortment: alleles of different genes segregate independently into gametes
