Why are there no green mammals in the animal kingdom?
Mammals do not have green pigment in their skin or fur because they do not have the necessary genes to produce green coloration. This is why there are no naturally occurring green mammals in the animal kingdom.
If an organism has XX genes it is a?
If an organism has XX genes, it is typically female in species where females have two X chromosomes, such as in humans and many mammals.
Some mammals have genes for fur color that produce pigment only when the outside temperature is above a certain level This pigment production is an example of how the environment of an organism can?
influence the expression of certain genes
What is holandric genes?
Holandric genes are genes located on the Y chromosome and are passed down from father to son. These genes are specific to males and play a role in determining male-specific traits and characteristics. Examples of holandric genes include those involved in determining certain aspects of male sexual development.
How is the cloning of genes different from the cloning mammals?
The difference between cloning genes and cloning a mammal is that when a gene is cloned, it is typically removed from a DNA sequence and inserted into an organism. The cloning of a mammal, however, is when a somatic cells from the mammal are cloned to produce a "copy" of the mammal.
Homeotic genes are best describe as?
Homeotic genes are a group of regulatory genes that control the development and spatial organization of an organism's body plan. They play a crucial role in determining the identity of body segments and the formation of structures in specific locations. Mutations in these genes can lead to significant morphological changes, often resulting in the transformation of one body part into another. In many organisms, including fruit flies and mammals, homeotic genes are essential for proper embryonic development.
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
What evidence is there that whales have formed from land mammals?
Some have the remains of hind legs and a pelvis still inside their bodies. On top of that, land was where mammals evolved.
Does prokaryotes have genes?
Of course they have genes. They need genes for survival and reproduction.
Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
Are linked genes genes located on the same chromosome?
Yes, linked genes are genes located on the same chromosome.
Are master genes and homeotic genes the same thing?
Master genes and homeotic genes are related but not the same. Homeotic genes are a specific type of master gene that regulate the development of anatomical structures in organisms, determining the identity of body parts. Master genes generally refer to genes that control the expression of other genes and play crucial roles in regulating developmental processes. Thus, while all homeotic genes are master genes, not all master genes are homeotic genes.
