A study revealed that the Y chromosome, which determines male sex, is degenerating and may vanish in a few million years.

It is important to note, however, that no chromosomal duplication occurs during this stage. What happens during meiosis II? During meiosis II, the two cells once again cycle through four phases of ...

c) For the inverted duplications, the ideograms and partial karyotypes of two chromosome 15s show the two different sizes of inv dup (15) chromosomes. The smaller inv dup (15), on the left ...

Chromosome imbalance caused by the absence or duplication of chromosomal material most often results in spontaneous abortion. In a live birth, chromosomal imbalance generally produces some ...

A diagram showing the evolution of vertebrate chromosomes from an invertebrate ancestor through two whole-genome duplication events (shown as starbursts). For simplicity, only one ancestral pair ...

Almost all of the DNA duplication in your body is carried ... Others cells in your body contain 46 chromosomes: 23 from your father and 23 from your mother. Your egg (or sperm) cells contain ...

These sex chromosome variations are found throughout the human population, and they lead to a variety of health disorders but ...

During the first two months of a horse's gestation, 42 percent of miscarriages and spontaneous abortions were due to ...

We are interested in the mechanism of chromosome replication, a process that is highly conserved across eukaryotes and that involves the duplication of both the chromosomal DNA and its associated ...

Our bodies absolutely need carbohydrates for energy. It’s a matter of survival. So much so, that some human populations have ...

Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...

All array platforms will detect copy number variations including deletions, duplications, unbalanced translocations, some marker chromosomes and aneuploidy. SNP arrays have the added advantage of ...
