What is the definition of secondary polycythemia?
Secondary polycythemia is an acquired form of a rare disorder characterized by an abnormal increase in the number of mature red cells in the blood. Secondary polycythemia is also called secondary erythrocytosis.
What occurs during nondisjunction?
If nondisjunction occurs, abnormal numbers of chromosomes may find their way into gametes, and a disorder of chromosome numbers may result.
What chromosomes do human have 22 of?
The chromosomes number1- 22 is called autosomes and pair number 23 is called as sex chromosome.
What is the medical term meaning cancer characterized by an increased number of abnormal white blood cells?
What chromosomes are autosomes?
The 44 chromosomes that are not sex chromosomes. 1st through the 22nd pair. The X and Y chromosomes are the only chromosomes not autosomes.
What is the medical term meaning cancer characterized by a progressive increase in the number of abnormal leukocytes?
Leukemia (loo-KEE-mee-ah) Is a malignancy characterized by a processive increase of abnormal leukoytes. (''leuk'' means white and ''emia'' means blood condition).
What is the medical term meaning abnormal increase in red blood cells?
Macrocytosis is the term meaning abnormally large red blood cells. Macrocytosis is seen in a number of RBC disorders. Megaloblastic anemia is one of the best characterized ones. It is cause by vitamin B12 deficiency.
What is a dipliod number?
The diploid number is the total number of chromosomes found in the autosomes, or non-gamete cells of an organism. The diploid number includes both chromosomes of each homologous pair. Gametes, on the other hand, carry only one chromosome from each homologous pair; they are haploid rather than diploid. Gametes therefore carry half the number of chromosomes that autosomes do.
Nondisjunction can alter the number of chromosome as well as autosomes?
Nondisjunction is a very bad thing and cells and can lead to lying of the cell.
What is an increase in the number of abnormal leukocytes?
leukemia
How many acrocentric chromosomes does a mouse have?
Diploid chromosome number in standard laboratory mice (genus Mus) is 40: 19 autosomes and the X and Y sex chromosomes. Whereas the autosomes and the X Chromosome are telocentric (centromere at one end of the chromosome), the Y chromosome is acrocentric
How many autosomes are ther in a gamete?
Normal body cells contain pairs of chromosomes. For example, in humans there are 23 pairs of chromosomes. Of these, 22 pairs (=44 chromosomes) are autosomes and one pair is the sex chromosomes. When gametes are made the number of chromosomes is halved. This is so that when two gametes fuse during fertilisation, the normal chromosome number is restored. So in humans, gametes contain 23 singlechromosomes. Of the 23 single chromosomes in a gamete, 22will be autosomes and one will be a sex chromosome. So, if your question is about humans, the answer is: 22. See: http://www.bbc.co.uk/schools/gcsebitesize/biology/cellprocesses/celldivisionrev3.shtml
