How is it still balanced if, let's say we have 100% chromosome A and 100% chromosome B. In simple translocation, 25% of chromosome A moves to chromosome B, to get 125% genetic material. This is unbalanced (I am referring to individual chromosomes). Together, we still have 200% genetic material but individuall it is not

Can simple translocations ever be balanced? I know with reciprocal translocations that if you're swapping the same *amount* of genetic material, it would be balanced, but if not, it would probably be unbalanced. (I'm referring to the genetic material of each chromosome, and not the total genetic material). But simple translocations on the other hand, you're adding part of a chromosome to another without swapping. So it's not possible to have a balanced simple translocation, correct?
A prairie grass species called "little bluestem" is tetraploid. It has four complete sets of chromosomes. There are ten kinds of chromosomes; in other words, each complete set of chromosomes has a total of 10 chromosomes. A single somatic cell (e.g., a cell in a leaf) will have 40 chromosomes, 4 of each kind of chromsome, i.e., 4 of the number 1 chromsome, 4 of the number 2 chromsome, etc. The illustration below shows prophase of meiosis 1 in chromosome number 10. In a diploid cell, there would be one tetrad (group of 4 chromatids) for each kind of chromosome. For example, there would be one tetrad for chromosome 8, one for chromsome 9, etc. When the tetraploid little bluestem undergoes meiosis, how many of chromosome number 10 will each sperm cell carry?
"If a fragment of a chromosome breaks off and then reattaches to the original chromosome but in the reverse direction, the resulting chromosomal abnormality is called a translocation." The above statement is True or False? and Explain
In an electrophoretic gel across which is applied a powerful electrical alternating pulsed field, the DNA of the haploid fungus Neurospora crassa (n = 7) moves slowly but eventually forms seven bands, which represent DNA fractions that are of different sizes and hence have moved at different speeds. These bands are presumed to be the seven chromosomes. How would you show which band corresponds to which chromosome?
The following diagram represents two nonhomologous chromosomes: A B • C D E F G R S • T U V W X What type of chromosome mutation would produce of the following groups of chromosomes? Q. A B • C D R S • T U V W X E F G
In a germline progenitor cell before DNA replication (2N), a translocation occurred between a telocentric and submetacentric chromosome resulting in a translocation heterozygote. The location of the translocation is illustrated below. Draw the Prophase I pairing conformation that would result from this translocation. The four types of chromosomes you have now can be labeled as follows: T-WT (telocentric wild type), T-TL (telocentric translocation), SM-WT (submetacentric wild type), and SM-TL (submetacentric translocation). Using these labels, list (please do not draw) the possible outcomes of Anaphase I and the possible phenotypes for each outcome. Please explain your reasoning for each phenotype in a few words. asap
Two phenotypically normal parents produce a phenotypically abnormal child in which chromosome 5 is missing part of its long arm but has a piece of chromosome 7 attached to it. The child also has one normal copy of chromosome 5 and two normal copies of chromosome 7. With regard to chromosomes 5 and 7, what do you think are the chromosomal compositions of the parents? Would it most likely be reciprocal translocation? It wouldn't be simple translocation because then the child would have the entirety of one chromosome and only some of the other, but in this case, there is only partial chromosome 5 and chromosome 7?
A chromosome with the following gene order has a paracentric inversion of BCDE. A B C D E F • G H If a cross-over occurred between C and D, what would the resulting chromosomes look like?
What types of chromosome mutations are required to change this chromosome into the following chromosomes? (In some cases, more than one chromosome mutation may be required.) Q. A B • C F E D G
Researchers have discovered that some regions of chromosomes are more likely than others to cross over, these areas of frequent crossing over are called "recombination hot spots". Gene A and B are 500,000 bp apart - the genes are either side of a recombination hot spot. Gene C and D are also 500,000 bp apart but the region containing genes C and D are not near a recombination hot spot. Would the map distance between A and B be the same as the map distance between C and D? Explain your answer.
