Biology

In a certain insect, body color is determined by a gene with two alleles (C and c), and wing pattern is determined by another gene with two alleles (W and w). The allele C gives black body color and is dominant over c (which gives white body color), and the allele W gives striped wings and is dominant over w (which gives plain wings). If a double - heterozygous insect (CcWw) is crossed with an insect that is homozygous recessive for both genes (ccww), what fraction of the offspring will have a black body and plain wings?
