What does hetero mean in biology?
hetero refers to the sexual orientation of an organism. Sexual attraction is a sexual behavior. The term Hetero is actually a shortening of Homo, which means “same species”. This term was initially used to describe interspecies sexual attraction.
Hetero means attraction between members of the same species. These species are sexual species or organisms that can reproduce sexually. Hetero refers to sexual reproduction. In order to reproduce, an organism needs two different sex cells: a male one called a sperm and a female one called an egg.
Sexual reproduction is the combination of two sexual cells that form a new one, a new individual with unique characteristics. During sexual reproduction, a male and a female combine their genetic material to produce a new egg or sperm.
What does heterocentric mean in biology?
heterocentric means that the sex cells in an individual are not located within their own bodies, but instead are developed in a different individual, the one with the sex cells. Almost all sexually reproducing animals are heterocentric, including humans.
In humans, each egg is produced in an ovary of one sex and each sperm is produced in a testicle of the other sex. In bisexual species, such as many species of fish, invertebrates, amphibians, and reptiles, both Heterocentric means that the center of a cell is not at its nucleus.
In most animal cells, the center of the cell is the location of the Golgi apparatus, the organelle that processes and packages proteins and other macromolecules before they are sent out to other parts of the cell. The Golgi apparatus is also where many cell-signaling proteins are produced and stored.
In other words, the Golgi apparatus is where the cell “makes” its center.
What does heterozygous mean in biology?
Heterozygous means that you have two different alleles for a particular trait. One allele may be a dominant allele, meaning that it is “expressed” or “dominant” over the other allele. If you have two copies of the dominant allele, you will express the trait (or express the trait more than if you have two copies of the recessive allele).
The other allele may be a recessive allele, meaning that it is “inactivated” Heterozygous means that a person has two different alleles. A dominant allele is one that is expressed even if an individual has two copies of the recessive allele.
Thus, a heterozygous dominant trait will express itself when an individual has two dominant alleles. A recessive trait is one that must have two copies of the recessive allele to express itself. A double recessive trait will not express itself with just one copy of each.
What does heterozygous mean in terms of survival?
Heterozygous means that you have two different alleles of a gene, so one copy of the version created in your parents, and one copy of the different version that developed in your grandparents or great grandparents. So, if you have a recessive trait, such as sickle cell anemia or color blindness, you need to have two copies of the recessive allele to be born with the trait.
If you have a dominant trait, such as blue eyes, you only need one copy of Many genes are linked to a disease. If a person has two copies of a disease-causing version of a gene, they will get that disease.
If they have one copy of the disease-caining version and one normal (or non-disease-causing) copy of the gene, they will not get the disease.
A heterozygous, or “hetero” person, has one copy of a disease-causing version of the gene and one copy of
What does heterozygous mean in terms of sex?
Heterozygous means that a given trait is expressed in two different ways in either sex. This is called heterozygous dominance. For example, most people have two different types of color pigment in their eyes. Those who have a lot of one color are red-eyed; the other variety has a lot of the other color and are called blue-eyed. These two different types of pigment are usually recessive. In other words, to get a red-eye color, you need to have Heterozygous means a person is genetically different from their parents in one of the pair of chromosomes that determines their sex. In some cases, one of the two parents has only one copy of the gene for a trait while the other parent has two. We call these recessive traits. If a child has two copies of the recessive trait, they will have the trait, while a child who has only one copy will not. If you are a carrier of a gene for a recessive trait
