In the the fruit fly drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. at another gene locus on the same chromosome, there is a dominant gene for red eyes and its recessive allele for purple eyes. a male that was heterozygous at both gene loci was mated with a female that was homozygous for both recessive alleles and the following results were observed among the offspring:

normal wings and red eyes - 420
vestigial wings and red eyes - 80
normal wings and purple eyes - 70
vestigial wings and purple eyes - 430

according to these data, what is the distance, in centimorgans, between these 2 gene loci? (enter the number only without the units. for example, 100 cm would be entered as 100)
