Somatic cells are all the cells that make up an organism, including the organ, muscle, fat, bone, and skin cells. The only exceptions are the egg and sperm cells, also called germ cells, which are involved in sexual reproduction. Although somatic cells differ greatly in their form and func...
Fertilization occurs when the sex cells of a male (sperm) and female (egg) fuse together to make a diploid single cell. This cell contains the paired genetic information of both parents. A fertilized egg embeds itself on the uterine wall and as cell division occurs, it will grow from an ...
1. Understanding Haploid and Diploid: - Haploid cells contain one set of chromosomes (n), while diploid cells contain two sets (2n). In humans, haploid cells are typically gametes (sperm and eggs), whereas diploid cells are somatic cells. 2. Analyzing the Options: - A. Spermatogonial cells...
How many chromosomes are in a human somatic cell? How many chromosomes are found inside the nucleus of every human cell except egg and sperm cells? How many chromosomes are in a human egg cell? What is diploid? How many chromosomes are in a human cell?
Acquired mutationsare not passed down if they occur in the somatic cells, meaning body cells other than sperm cells and egg cells. Some acquired mutations occur spontaneously and randomly in genes. Other mutations are caused by environmental factors, such as exposure to certain chemicals or radiatio...

Somatic cells forming the caput tubule's lumen also express GFP-CETN2 in their basal bodies (green). (C) Diffuse γ-tubulin (red, arrow; blue, DNA) surrounds the GFP-CETN2–expressing centrioles in caput epididymal sperm (upper inset: green, arrow; lower inset: DIC). (D) ...
Poised enhancers (PEs) represent a genetically distinct set of distal regulatory elements that control the expression of major developmental genes. Before becoming activated in differentiating cells, PEs are already bookmarked in pluripotent cells with u
Therapeutic cloning, also called somatic cell nuclear transfer, is a way to create versatile stem cells independent of fertilized eggs. In this technique, the nucleus is removed from an unfertilized egg. This nucleus contains the genetic material. The nucleus also is removed from the cell of a...
How many chromosomes do sperm cells have? How many chromosomes are in a somatic cell of a horse? How many chromosomes do dogs have in their somatic cells? During prophase II, a diploid organism contains how many copies of each gene?
