E indicates the dominant allele and e indicates the recessive allele. 16 terms. Remove the flies you choose for mating and place in a new vial. A mutation is considered an alteration in the genome of an organism. Then if you breed such a female with a white eyed male, some of the female offspring will receive an X chromosome from the mother containing the white mutation, as well as the white mutant allele on the X chromosome from the father. E indicates the Obtain a vial of F1 flies from your teacher. 0, Critical Values of the Chi-Squared Distribution This is an excellent adaptation for the College Board lab on genetics.
