What technical term given to the type of chromosomes that has two equal arms?

Which type of chromosome has two equal arms?

A metacentric chromosome is a chromosome whose centromere is centrally located. As a result, the chromosomal arms (i.e. p and q arms) are almost equal in length.

What are chromosomes of the same type called?

Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism’s mother; the other is inherited from the organism’s father.

What is the term for two similar structured chromosomes?

​Chromatid

During cell division, the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes. Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.

What is the meaning of Submetacentric?

: having the centromere situated so that one chromosome arm is somewhat shorter than the other.

What is the difference between Acrocentric and Telocentric?

A telocentric and an acrocentric chromosome differ from each other based on the position of the centromere. The telocentric chromosomes are present at the end or terminal of the chromosomes while the acrocentric chromosome is present between the center and the terminal, which is at the sub-terminal position.

What is an organism’s appearance called?

The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.

What is the term diploid?

Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. … The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).

What are the heterozygous genotypes?

(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What is division of the nucleus called?

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

How are those two molecules organized structurally to form a chromosome?

How are those two molecules organized structurally to form a chromosome? Long strands of DNA are wrapped around the proteins to condense the DNA so it will fit inside the nucleus of the cell. … Each cell has 46 chromosomes (23 pairs); one in each chromosomal pair is inherited from each parent.
