What is the predicted percentage of homozygous recessive offspring in this cross?
Which term refers to an organism's physical appearance
If one parent is heterozygous, what does that mean? Choose all that apply.
One dominant allele, one recessive allele
It means they are a hybrid
They have one capital letter and one lowercase letter as symbols
They can pass on either allele
a percent, ratio, or fraction that describes how likely it is that an event will occur
diagram predicting the possible gene combinations that might result from a genetic cross
A _______ is an alternative form a gene.
Red (R) is dominant over white (r). How can a flower be white?
It can have RR and be white.
It has to have rr.
It has to have rR
There is no way it can be white until the third generation.
