Answer:

Polygenic inheritance

Explanation:

When multiple genes present at different loci on chromosomes regulate a single genetic trait, the trait is said to be polygenic and the inheritance is a polygenic inheritance. The phenotype of the individual is regulated by an allele of each gene in an additive manner. The sum total of phenotypic effects of each allele of all the genes determines the final phenotype of the individuals.

These traits not present in discrete contrasting pairs (such as tall and short) but exhibit quantitative variations. For example, skin color in humans is regulated by multiple genes and the phenotype of the individual ranges from very light to very dark with many intermediates in between.

The surface of the cerebral hemispheres consists of ridges and grooves. The shallow grooves are called ________.
Yuri [45]

The surface of the cerebral hemispheres consists of ridges and grooves. The shallow grooves are called Sulci.

<h3>What is Cerebral Hemisphere?</h3>

The brain is formed by two cerebral hemispheres. It is separated by a groove called longitudinal fissure. The brain is divided into left and right cerebral hemispheres. These consist of an outer layer of gray matter called the cerebral cortex which is supported by an inner layer of white matter.

In placental mammals, the hemispheres are connected by the corpus callosum which is a very large bundle of nerve fibers.

There are three poles of the cerebral hemispheres:

1. The occipital pole

2. The frontal pole

3. The temporal pole

The thin layers of cells that cover the cerebral hemispheres are called the cerebral cortex. These raised ridges of tissue on the surface of the cerebral cortex are known as gyri while the shallower grooves are called sulci.

Thus, the surface of the cerebral hemispheres consists of ridges and grooves. The shallow grooves are called Sulci.

Mitosis is for all cells, except sex cells. Daughter cells relate more to sex cells than other cells. Sex cells go through meiosis to create daughter cells. This also gets copies DNA. This gets rid of B

Basically: Mitosis is how we make new cells from the original cell (Think Zygote cell)
