What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
Explain the exchange of chromosome segments between chromatids of homologous or non-homologous chromosomes?
a. crossing over b. independent assortment or c. random fertilization
What are 4 types of chromosome structural changes?
The four types of alterations of chromosome structure are deletion, duplication, inversion, and reciprocal translocation. Deletion is the loss of one or more nucleotides from a gene by mutation; the loss of a fragment of a chromosome. Duplication is repition of a part of a chromosome resulting from fusion with a fragment froma homologous chromosome. Duplication can result from an error in meiosis or from mutagenesis. Inversion is a change in a chromosomeresulting from reattachment of a chromosome fragment to the original chromosome, but in a reverse direction. Mutagens and errors during mesosis can cause inversions. Translocation is the attachment of a chromosomal fragment to a nonhomologous chromosome.
What is the difference between translocation and nondisjunction?
Nondisjunction is when a Chromosome is unable to separate correctly during cell devision. Translocation (In Chromosomes) is when an abnormality is caused by the rearrangement of parts between non-homologous Chromosomes.
How many chromosomes are in a mouse's gamete?
Gametes only have one set of each chromosome pair so that when two gametes come together, the chromosome number in the embryo is correct. There are 19 autosomes and one sex chromosome in the mouse gamete.
What are The two sets of chromosome that come from the female parent and the male parent?
heterozygous
How many chromosomes are in a homologous pair?
in a homologous chromosome there are two chromosomes ( a chromosome and a sister chromosome)
Chromosomes that have a corresponding chromosome?
Homologous
What is a chromosome called with matching information?
Chromosome pairs that contain matching information are called "homologous".
What can homologous chromosomes be called?
chromosome pairs
What portion of the human Y chromosome is homologous to the human X chromosome?
biology!
The two copies of each chromosome in body cells are called?
Homologous pairs.
When is the haploid chromosome created?
homologous chromosomes separate.
One of the two homologous strands of a chromosome?
Chromatid
What is the differences between bivalent and tetrad?
The bivalents are homologous chromosome containing a total of two chromosomes. On the other hand, tetrad is the homologous pair of chromosomes containing four chromosome.
The haploid chromosome number is created when?
homologous chromosomes separate.
Is homologous recombination a type of mutation?
No. A mutation can change an allele into any other allele. Homologous recombination can only change an allele to the allele of the homologous chromosome.
