How flies which are recessive homozygous

Reference no: EM1395728

In drosophila, an autosomal recessive mutation sepia (se) (on chromosome 3) causes sepia eye door, and another recessive mutation scarlet (st), also on chromosome 3, causes scarlet eye color. distance between the two genes is 18 map units apart. flies which are recessive homozygous by both of these mutations have white eyes (NOTE: gene w is NOT used in this problem) a) cross a female homozygous by both mutations to a true breeding wild type male. then cross a F1 mlae to a F1 female. give the scheme of the cross, the resulting F2 phenotypes, and their percentages. b) cross a tru breeding sepia eyed female to a true breeding scarlet eyed male. then cross a F1 male to a F1 female. give the scheme of the cross, the resulting F2 phenotypes and their percentages.
