Another function of the sperm is to determine the sex of the future baby. Depending on the chromosomal distribution that takes place during meiosis, the sperm cell will possess either the X chromosome (female sex) or the Y chromosome (male sex). Structure of a human sperm cell In 1677, th...
What is a chromosome? A. a portion of DNA that codes for a single protein B. a sequence of three nucleotides that codes for a single amino acid C. a structure within the cell nucleus that houses genes D. a portion of a protein that codes for a single amin ...

Most of an organism's DNA and genes are packed into chromosomes that lie within each cell's nucleus. A chromosome is a protein-based structure that carries genomic information from one cell to the next. Although genomics can apply to any organism, most of the attention has been on the huma...
In this article, we’ll break down the difference, give you simple definitions of the key terms (likechromosomeandallele), and provide several simple examples. Quick summary An organism that has the same two copies of a gene is consideredhomozygousfor that trait, while an organism that has di...
“Several research groups are now working together to investigate what effect this may have on the DNA molecule. We already know that R-loop regions are associated with DNA sequences that contain active genes, and that this can lead to chromosome breaks and the loss of genetic information.” ...
Finding a segment of chromosome where several identical markers run together in association with a disease or trait suggests that there may be an ancestral founder effect. The highest frequency for blue eyes in the population is around the Baltic Sea and this may be where the original genetic ...
Definition Oligospermia, also called oligozoospermia, is defined as having a low sperm count in the ejaculate. Oligospermic semen samples are considered of poor quality, and males diagnosed with oligospermia are likely to experience trouble conceiving due to the low amount of sperms able to ...
Q.1. Why is mitosis called equational division? Ans: The cell is also known as equational cell division because the chromosome number in the parent cell and daughter cell remains the same.Q.2. What are the stages of mitosis?Ans: The stage of mitosis are as follows:a. Prophaseb. ...
