A non-gamete cell, or somatic cell, typically has two alleles for each gene, one inherited from each parent. This means that in diploid organisms, such as humans, somatic cells contain two sets of chromosomes, resulting in two alleles per gene. However, some organisms can have different ploidy levels, affecting the number of alleles present.

What is the name of the male gamete of an animal called?
The male gamete is called a sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon, whereas a non-motile sperm cell is called a spermatium. The female gamete is called an egg cell. They are also known as ova (singlular = ovum).
What is a non example for allele?
A non-example of an allele would be a chromosome. While alleles are specific versions of a gene that determine particular traits, chromosomes are long strands of DNA that contain many genes, including multiple alleles. For instance, the gene for flower color in a plant can have different alleles (like purple or white), but the entire chromosome that carries these genes is not an allele itself.
What happens if a cell goes through non-disjunction?
The failure of chromosomes to separate during mitosis results in one gamete that lacks a chromosome and another with 2 chromosomes. Gametes with improper number of chromosomes are called aneuploid gametes. Aneuploid gametes are the most common cause of spontaneous abortion and handfuls of other congenital disorders that varies depending on donors gamete content.
What effect does non disjunction have on the chromosome number of the gametes?
A gamete can possess n+1 or n-1 chromosomes as a result of nondisjunction.
What is sickle cell Trait The condition is Autosomal and there is Codominance between alleles what does this mean?
sickle cell trait is inherited from one set of gene alleles from both parents. if you get two traits together it will cause sickle cell anemia which is a disease, sickle cell trait is not a disease. i dont know what autosomal means!! i dont know what codominance means!!
How many autosomes are present in a mouse gamete?
A normal mouse gamete would have 19 autosomes.
What type of cell is Meiosis?
That type of division is done by a gamete (sex cell). mitosis is performed in a somatic (non-reproductive) cell.
What is the name of the male gamete of an animal called?
The male gamete is called a sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon, whereas a non-motile sperm cell is called a spermatium. The female gamete is called an egg cell. They are also known as ova (singlular = ovum).
Are gamete cells mutations and somatic cells mutations inheritable?
Since only gamete cells actually participate in the creation of a new organism, it is only the mutations in gamete cells which are inheritable; mutations in somatic cells are not inheritable.
What are tetrasomics?
Addition of a pair of chromosomes to a diploid set results in tetrasomic condition. Tetrasomics may be represented as 2N+2. Tetrasomics may arise when two abonormal gametes produced as a result of non-disjuction unite, with each gamete carrying an extra chromosome of the same pair as shown below. AABBCCDD a diploid cell----meiosis and non disjuction AABC Gamete carrying an extra chromosome--- BC Gamete short of one chromosome. Now if this Gamete (AABC) unites with another gamete of the same kind (AABC), we get tetrasomic AAAABBCC.
What is a non example for allele?
A non-example of an allele would be a chromosome. While alleles are specific versions of a gene that determine particular traits, chromosomes are long strands of DNA that contain many genes, including multiple alleles. For instance, the gene for flower color in a plant can have different alleles (like purple or white), but the entire chromosome that carries these genes is not an allele itself.
Gametes that are motile are often called?
A motile gamete is a sperm cell; it is motile because it has a flagellum and it swims around, and it is a gamete because, combined with the non-motile ovum, it can form a zygote and hence a new organism.
What happens if a cell goes through non-disjunction?
The failure of chromosomes to separate during mitosis results in one gamete that lacks a chromosome and another with 2 chromosomes. Gametes with improper number of chromosomes are called aneuploid gametes. Aneuploid gametes are the most common cause of spontaneous abortion and handfuls of other congenital disorders that varies depending on donors gamete content.
What effect does non disjunction have on the chromosome number of the gametes?
A gamete can possess n+1 or n-1 chromosomes as a result of nondisjunction.
Does oogamy always involve fertilization from gametes of different sizes?
Yes, oogamy is a form of sexual reproduction where the female gamete is much larger than the male gamete.
What are non-mendelian trait?
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
What is sickle cell Trait The condition is Autosomal and there is Codominance between alleles what does this mean?
sickle cell trait is inherited from one set of gene alleles from both parents. if you get two traits together it will cause sickle cell anemia which is a disease, sickle cell trait is not a disease. i dont know what autosomal means!! i dont know what codominance means!!
