Written answer/problems. Type the full answer to each part of the question.

Describe the characteristics that are similar between the Drosophila homeotic genes and the mammalian Hox genes. Be sure to include the general functions of the proteins these genes encode.

Answer 1

Homeotic gene, any of a group of genes that control the pattern of body formation during early embryonic development of organisms. These genes encode proteins called transcription factors that direct cells to form various parts of the body.

Some "control" genes are common to many organisms (they are homologous — inherited from our common ancestor). For example, Hox genes help lay out the basic body forms of many animals, including humans, flies, and worms. They set up the head-to-tail organization
