What name is given to genes that regulate the genes involved in determining patterns of anatomical development?
These genes are called "homeotic genes" or "Hox genes." They play a crucial role in controlling the body plan of an organism during development by regulating the expression of other genes that determine anatomical structures.
Mutations in these genes lead to transformation in the identity of entire body parts?
Homeotic genes, also known as Hox genes, are responsible for controlling the identity and positioning of body parts during embryonic development. Mutations in these genes can lead to dramatic changes in body structure, such as transformations in the identity of entire body parts.
What do homeotic genes direct?
A homeotic gene, known as a Hox gene controls the development of metazoa or animal body segments. An exaple of a homeotic mutation that occured in Drosophilia would be a leg developing where an antenna would normally be located.
What is the evolutionary significance of duplication?
Duplication can lead to the evolution of new genes with novel functions or regulatory patterns. It provides genetic redundancy that can buffer against deleterious mutations, offering evolutionary flexibility and facilitating the evolution of complex traits. Additionally, duplicated genes can diverge in function, contributing to genetic innovation and adaptation in response to changing environments.
How can hox genes provide evidence of evolution?
The hox genes (actually a subset of the Homeobox genes) were important in evolutionary thought because they provided a basis for saltationism and punctuated equilibrium.These genes direct morphogenesis, defining the body plan of organisms. Thus, a small mutation in any of them can lead to an enormous change in the physical appearance of an organism.

A class of master genes necessary for normal development in eukaryotes is called?

What kinds genes that regulate development suggest that flies and mice are related?
Homeotic Genes
What is another word for Hox genes?
Hox genes are a type of homeotic gene. They can be called body plan genes.

In what organism were homeotic genes first indentified?
A spontaneous true breeding homeotic gene mutant Pps-1 with distinct partial petaloid sepals was detected in the population of downy mildew.
What is one way master control genes or homeotic genes could have affected evolution?
Master control genes or homeotic genes can influence the development of body structures in early developmental stages. Mutations in these genes could lead to significant changes in body plans, ultimately affecting the way organisms evolve and adapt to their environments. For example, a mutation in a homeotic gene could result in the development of an extra pair of wings in an insect, providing a selective advantage and driving evolutionary changes in that population.
Why does it take only a few homeotic genes to control the development of a eukaryote?
Different genes are turned on or off in the different cell types as a result of specialization
