What do you mean by homologous chromosomes?
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 are homologous chromosomes Brainly?
Homologous chromosomes or homologs are a pair of two chromosomes with the same length, centromere position, and staining pattern in a karyotype. What is the relationship of these two pairs of chromosomes?
What are homologous chromosomes Class 9?
Homologous chromosomes are a chromosomal pair that contains the maternal and paternal chromatid of the same length and gene position, and that are joined at the centromere. The gene position on each chromosome is the same, but they may contain different alleles of gene.
What do you mean by homologous chromosomes Class 10?
Homologous chromosomes are defined as two pieces of DNA within an organism who is a diploid (2n) which carry the same genes one from each parent i.e. one from a father and one from the mother. This suggests that both parents contribute to the complete genome of an organism.
What is homologous chromosome Class 11?
Homologous chromosomes – Homologous chromosomes are defined as a set or pair or chromosome which offspring received and got from its parent one from the maternal parents and one from the paternal parent.
What is a homologous chromosome quizlet?
Homologous Chromosomes. Chromosomes found only in diploid cells, that are the same size, the same shape, have the same instructions or genes, but not necessarily the same information or alleles.
What do you mean by homologous chromosomes Class 12?
Homologous chromosomes are chromosomes pairs (one from each parent) that are similar in length, gene position, and centromere location. The position of the genes on each homologous chromosome is the same, however the genes may contain different alleles.
What is a Nondisjunction quizlet?
Nondisjunction refers to the failure of pairs of chromosomes or sister chromatids to separate during meiosis or mitosis.
What are homologous chromosomes Ncert?
Homologous chromosome: A set of one maternal chromosome and one paternal chromosome that pair up with each other inside a cell. … Homologous regions code for the same gene.
What is chromosome 10 CBSE?
A chromosome is a DNA molecule that consists of a part or all of the genetic material of an organism. The chromosome is present in the nucleus of each cell, and it is packaged into thread-like structures. … Males have one “X” and “Y” chromosome, while females have two copies of the “X” chromosome.
What are homologous chromosomes ICSE?
Homologous chromosomes are chromosome pairs containing a maternal and a paternal chromatid that are similar in length, gene position, and are joined at the centromere. The position of the genes on each homologous chromosome is the same, however, they may contain different alleles of the genes.
