What percentage of Edwards Syndrome fetuses are stillborn or miscarried?
comparative genomic hybridizations a method that can be used to detect what changes in chromosome structure
an organism that has only one copy of a particular chromosome instead of the normal two copies is said to be
the term meiotic ---refers to the failure of chromosomes to separate normally during meiosis, this results in haploid cells that have too many or too few chromosomes/
in organisms that are normally diploid, a monosomic individual is designated---
a(n) --- organism is one that contains three or more sets of chromosomes
polyploid plants that have odd numbers are often ---- and that have even number are ----
a triploid plant is advantageous in agriculture because it is often---
Liver cells of humans may be triploid (3n). tetraploid ( 4n), or even octaploid (8n). this phenomenon is best described as
the three most common autosomal trisomies in human are those involving what chromosomes
polyploidy is commonly found in species of
an organism that has at least two set of chromosomes from two or more different species is best described as a(n)
---- is the gain or loss of individual chromosomes to or from a complete set.
the failure of chromosomes to segregate properly during mitosis or meiosis is called
true or false: all copy number variations found in humans are known to be associated directly or indirectly with genetic or infectious disease
an organsim that has three copies of a particular chromosome instead of the normal two copies is said to be
in this figure, the blue and red chromosomes represent chromosome number 14 and 21, respectively. an individual with the circled chromosomes has---- -----syndrome.
unlike trisomy or autosomes, trisomy X is often without serious phenotypic consequences. this is due to the fact that the additional X chromosomes is converted to an inactive ---- ---- in the somatic cells of the adult
individuals with down syndrome have three copies of chromosome 21. the extra copy is most likely to be due to ---- during meiosis I in the oocyte
in a triploid plant, the probability that meiosis will produce a gamete that is perfectly haploid or diploid is ---, where n is the number of chromosomes in a set. thus, the high probability of aneuploid gametes makes triploid plants sterile
