In the fruit fly Drоsоphilа, there is а dоminаnt 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 - 420Vestigial wings and red eyes - 80Normal wings and purple eyes - 70Vestigial wings and purple eyes - 430According 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)
