How do you rank the hereditary components nucleotide gamete chromosome and gene from small to large?
nucleotide, gene, chromosome, gamete
What do chromosomes become after they duplicate?
After chromosomes duplicate during the S phase of the cell cycle, they consist of two identical sister chromatids held together by a centromere. These sister chromatids later separate during cell division to ensure each daughter cell receives a complete set of genetic material.
How many chromosomes does a dragon have?
It is undetermined because a dragon is only a mythological character. There are no proofs that dragons exists or if they lived before. The only living dragon is the Komodo dragon and it is a lizard.
Sex Chromosomes
What chromosomes did the father contribute if a normal female is produced?
The father must have contributed an X chromosome if a normal female is produced.
Why do potatoes have more chromosomes than humans?
The number of chromosomes of a species has little to do with the complexity of the organism or the amount of DNA. The reason for this is, chromosomes are known to break and form two or more new chromosomes, or fuse into one. The chromosomes of the potato and the potato lineage may have undergone many such changes, and the human lineage may have undergone a different series, resulting in the potato having more chromosomes.
How many chromosome do congenital adrenal hyperplasia have?
The same number as any other human as the condition is not caused by the absence of an entire chromosome. 90% of cases are caused by an autosomal recessive of the CYP21 allele. So far there are at least 56 identified variations at this site that can cause the many variations of CAH.

Two chromosomes are homologous if they have the same genes at the same loci (position). In a homologous pair, there is one chromosome from the mother (maternal) and one from the father (paternal).
What two discrete ingredients make a chromosome?
A chromosome is primarily made up of two discrete ingredients: DNA and proteins. The DNA molecule contains the genetic information, while proteins, especially histones, help package and condense the DNA into a compact structure, allowing it to fit within the cell nucleus. Together, these components form the chromatin that constitutes chromosomes during cell division.
How many chromosomes in diploid cells in a monkey?
Diploid cells in monkeys typically contain 42 chromosomes. This number can vary among different species of monkeys, but for the common macaque, for example, the diploid chromosome number is 42. Each diploid cell has two sets of chromosomes, one inherited from each parent.
Why do abnormalities tend to be milder in x chromosomes?
Abnormalities tend to be milder on X chromosomes because of the phenomenon known as X-inactivation, where one of the two X chromosomes in females is randomly inactivated, leading to a "dilution" of the effects of mutations. Additionally, many genes on the X chromosome are present in two copies in females (XX) and only one in males (XY), allowing for a backup copy that can compensate for deleterious mutations. This dosage effect often results in milder phenotypic expressions of X-linked abnormalities in females compared to males.
Do asexual organisms have chromosomes?
Humans have 46 chromosomes, 23 from each parent. Out of those 46, two are the ones that define the individual's sex. The rest of chromosomas have no relation with detrmining the individual sex and that is why the may be called asexual chromosomes. S.V.
What statement best applies to chromosomes?
Chromosomes are structures within cells that organize and store genetic information in the form of DNA. Each chromosome consists of a single, long DNA molecule wrapped around proteins called histones, which help to compact and manage the DNA's structure. Humans typically have 46 chromosomes, arranged in 23 pairs, with one set inherited from each parent, playing a crucial role in heredity, cell division, and overall cellular function.
