Each pair consists of chromosomes of the same size and shape, and they also contain the same genes. The chromosomes in a pair are known as homologous chromosomes. As see in Figure 6.3.
What are two similar chromosomes called?
Pairs of similar chromosomes are called homologous chromosomes. During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.
What is the name for a matching set of chromosomes that have the same size and same band pattern?
Homologous chromosomes are identical, or matching, chromosomes. One chromosome in a homologous chromosome pair comes from the mother, the other from the father. The arrangement of homologous chromosome pairs is called a karyotype. Humans have 46 chromosomes, 23 pairs.
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.
How many genes are in a chromosome?
Chromosome 1 likely contains 2,000 to 2,100 genes that provide instructions for making proteins.
