In fruit flies, the allele for vestigial wings is recessive to the allele for normal wings. in a generation of fruit flies, 18 males and 15 females with vestigial wings are produced, and 43 males and 44 females with normal wings are produced. which of the following is the best conclusion you can make about the parents of this generation? both parents were heterozygous for wing type. one parent was heterozygous for wing type and the other was homozygous with normal wings. both parents were homozygous with normal wings. one parent had vestigial wings and the other was heterozygous for wing type.

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.
