Best answer: Is an allele A homologous chromosome?

So allele and homologue, these words are not synonymous ; but yes, alleles are always present on homologous chromosomes. One member of a homologous pair comes from father while another member comes from mother.

Is an allele the same as a chromosome?

An allele is one of two, or more, versions of the same gene at the same place on a chromosome. It can also refer to different sequence variations for several-hundred base-pair or more region of the genome that codes for a protein. Alleles can come in different extremes of size.

What is homologous in genetics?

A homologous gene (or homolog) is a gene inherited in two species by a common ancestor. While homologous genes can be similar in sequence, similar sequences are not necessarily homologous. Orthologous are homologous genes where a gene diverges after a speciation event, but the gene and its main function are conserved.

What is a chromosome real life example?

Frequency: The definition of a chromosome is a thread-like structure of DNA (nucleic acids and proteins) that carries genes. The “X” or “Y” gene that determines whether you will be a boy or a girl is an example of a chromosome.

What is the main difference between Chromatin and chromosomes?

Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.

Do all cells have homologous chromosomes?

All cells have homologous chromosomes except for the reproductive cells of higher organisms. Cells with homologous chromosomes are diploid. Reproductive cells, called gametes, are different. They contain only half the full number of chromosomes—one chromosome from each pair.
