does each member of a pair of homologous chromosomes have the same number of genes?
11676
One chromosome of each homologous pair comes from the mother (called a maternal chromosome) and one comes from the father (paternal chromsosome). Homologous chromosomes are similiar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.

Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state.

A gamete has one-half the number of chromosomes of a regular body cell. Homologous chromosomes are two chromosomes with identical DNA sequences. False, Homologous chromosomes contain the same genes as one another, but the DNA sequences vary.

heterologous chromosomes. When chromosomes are homologous, it means that they are the same, at least in terms of the gene sequences and loci. ... Homologous chromosomes have alleles on the same genes located in the same loci. Heterologous chromosomes have alleles on different genes.

Each cell in a normal human embryo has 23 pairs of homologous chromosomes, for a total of 46 chromosomes per cell.

A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during fertilization.

Answer and Explanation: While all autosomes are homologous chromosomes, not all homologous chromosomes are autosomes. Autosomes are the 22 pairs of non-sex chromosomes in...

A diploid cell is a cell that contains two complete sets of chromosomes. ... A homologous chromosome pair consists of one chromosome donated from the mother and one from the father. Humans have 23 sets of homologous chromosomes for a total of 46 chromosomes.

How do homologous chromosomes differ from sister chromatids? Homologous chromosomes are the two chromosomes that make a chromosome pair. A sister chromatid is the duplicate of each of the pair of homologous chromosomes. Each of the chromosomes that make up the homologous pair is derived from each parent.

Homologous Chromosomes. In diploid (2n) organisms, the genome is composed of homologous chromosomes. ... Homologous chromosomes are similiar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.

The cell has two sets of each chromosome; one of the pair is derived from the mother and the other from the father. The maternal and paternal chromosomes in a homologous pair have the same genes at the same locus, but possibly different alleles.

Each chromosome is one of two possibilities. Thus, there will be 2 x2 x 2 = 8 possible arrangements (or (2)3 = 8). 5. Humans have 23 pairs of homologous chromosomes.

Homologous chromosomes are the two chromosomes that make a chromosome pair. ... This means that at the gene level, each of the homologous pair could be carrying different alleles. On the other hand, sister chromatids are the exact duplicates and arise by duplication when the chromosomes undergo mitosis.

Human somatic cells have 46 chromosomes, including 22 homologous pairs and one pair of nonhomologous sex chromosomes. This is the 2n, or diploid, condition.

Homologous chromosomes are basically two similar chromosomes inherited from father and mother. They are homologous because they have the same genes, though not same alleles. During meiosis, the homologous chromosomes pair up during first prophase. When they do so, the homologous pair becomes known as a bivalent.

However, using the second definition, X and Y are not homologous -- so females have 23 pairs of homologous chromosomes and males have 22 homologous pairs and one non-homologous pair.
