What does it mean, really, if your 14-week-old fetus has a deletion on chromosome 12?
It's not delirium tremors and chromosome breakage and only a small number of users would be seriously harmed.
Haploid (n) chromosome numbers were determined from cells in diakinesis, metaphase I, and metaphase II of meiosis.
The locus of miniature at 36.1 is slightly beyond the middle of the chromosome.
Suppose we have two parents, both of whom are hybrids in respect to chromosome pair one.
We interpret this to mean that sable is far from yellow in the chromosome.
The number of such males depends on the distance apart of the two lethals in the chromosome.
Purple is an eye-color whose gen is in the second chromosome.
For this test we used yellow, which lies at the extreme left of the chromosome series.
Lindstrom of Iowa has led in research on the genetics of tomatoes, chromosome relations and mode of inheritance.
chromosome chro·mo·some (krō'mə-sōm')
A threadlike linear strand of DNA and associated proteins in the nucleus of animal and plant cells that carries the genes and functions in the transmission of hereditary information.
A circular strand of DNA in bacteria and cyanobacteria that contains the hereditary information necessary for cell life.
A structure in all living cells that consists of a single molecule of DNA bonded to various proteins and that carries the genes determining heredity. In all eukaryotic cells, the chromosomes occur as threadlike strands in the nucleus. During cell reproduction, these strands coil up and condense into much thicker structures that are easily viewed under a microscope. Chromosomes occur in pairs in all of the cells of eukaryotes except the reproductive cells, which have one of each chromosome, and some red blood cells (such as those of mammals) that expel their nuclei. In bacterial cells and other prokaryotes, which have no nucleus, the chromosome is a circular strand of DNA located in the cytoplasm.
