Chromosomes are counted differently depending on the stage of the cell cycle. To count the number of chromosomes, one could count the number of functional centromere. The number of DNA molecules is usually the number of chromatids.
During prophase 1, chromosomes condense, homologous chromosomes pair up, and crossing over occurs. In metaphase 1, homologous chromosomes line up at the cell's center. Anaphase 1 sees homologous chromosomes separate, while telophase 1 results in two daughter cells. Then, in meiosis 2, the process is similar to mitosis, with chromosome separation into four haploid cells.
Chromosomes
A lobster has 100 chromosomes. Humans have 46 chromosomes, the same as a lizard. A dog has 78 chromosomes, and a fly has 12 chromosomes.
No, sex chromosomes are not referred to as homozygous chromosomes. Homozygous chromosomes have identical alleles at a specific gene locus, while sex chromosomes determine an individual's biological sex. In humans, sex chromosomes include X and Y chromosomes.
chromosomes
male have one x and one y chromosome.
That sounds like kind of a description of chromosomes with DNA etc.
the readily stainable substance of a cell nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division
the chromosomes will move in the equatorial plane
well you see when the chromosomes split its called frigilious and the sex cell called the sex cell has a massive amount of fluid released called suffleisation and that results in suffle athorax and that's how to describe a chromosomes i think the previous answer is a little too much. Description of Chromosomes: coiled strands of genetic material simple. easy.
A karyogram is a photograph of an individual's chromosomes arranged in a standard format, while a karyotype is the set of chromosomes found within the nucleus of a eukaryotic cell. In simpler terms, the karyogram is the visual representation of the karyotype.
