* When they are formed, chromatins start folding in order to form chromosomes - A chromosome is therefore a complex of a double-stranded DNA and the packaging proteins. Main Parts of a ChromosomeThere are three main parts of a chromosome that include:...
Describe how the egg and sperm are produced or developed. How is genetic variation produced in meiosis? What is the name for the structure that is formed when the sperm and egg combine? What are chromosomes made up of? What are the 2 main causes of cell division?
Homologous chromosomes are very similar, but they are not identical. They carry the same genes (eg, hair or eye color), but they may not code for the same trait (eg, blonde hair or brown eyes). Stages of cell division Interphase – Replication of DNA. Most of a cell’s time is ...
(a) What are chromosomes made of? (b) Compare and contrast mitosis and meiosis.Cell division:After undergoing prophase, metaphase, anaphase, and telophase, the cell divides into two daughter cells with the chromosomal contents of the parent. The chromosomes are the components that...

Homologous chromosomes are Amorphologically & genetically different Bmorphologically different but genetically similar Cgenetically similar Dchromosomes which pair during synapsisSubmit The stage during which separation of the paired homologous chromosomes begin is APachytene BDiplotene CDiakinesis DZygoteneSubm...
The cells of an animal or higher plant have two sets of chromosomes: they are diploid. When gametes (sex cells) are produced, they have onlyone set of chromosomes: they are haploid. They have undergone a process of cell division calledmeiosis. During meiosis, crossing over occurs. This make...
Because women have two X chromosomes and men have only one, with the other being the Y chromosome, when a man with Fabry has children with a woman without it:all female children will inherit the mutated GLA gene no male children will inherit the disease, as they’ll only get a Y ...
A pair of chromosomes having similar which control the same characters are called homologous chromosomes.
