What is that chance that one of your non sex chromosomes is an enacct copy ot the same chromosome possed by your maternal grandmother?
The chance is 25%. Each individual inherits one set of chromosomes from each parent, so you have a 50% chance of inheriting a specific chromosome from your maternal grandmother. Since non-sex chromosomes come in pairs, the chance of inheriting an exact copy of one specific chromosome from your maternal grandmother is 25%.
What are pair of similar chromosomes called?
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
True or false in humans each pair of the 22 maternal autosomes has a homologous paternal chromosome?
True. In humans, each pair of the 22 maternal autosomes has a homologous paternal chromosome, meaning that the chromosomes are similar in terms of size, shape, and genes they carry. This ensures that genetic information from both parents is represented in the offspring's genome.
What does each member of the chromosome pair come from?
Each member of a chromosome pair comes from one parent; one chromosome is inherited from the mother and the other from the father. This means that for each chromosome in a pair, one is maternal and the other is paternal. These chromosomes carry genes that determine various traits and characteristics of an organism. In humans, for instance, there are 23 pairs of chromosomes, totaling 46, with half coming from each parent.
Can a sperm cell contain maternal chromosomes?
Absolutely (assuming you are referering to the maternal chromosomes of the man who is making the sperm) , the human set of chromosomes is composed of 46 pairs with half (23) coming from each parent. Mendel's laws suggest that each chromosome segregates and separates independently during mitosis (and subsequently meiosis) thus each gamete should contain a mixture of paternally and maternally derived chromosomes.
Where does each chromosome in a pair of homologous chromosomes come from?
Each chromosome in a pair of homologous chromosomes is inherited from one parent. One chromosome comes from the mother (maternal) and the other from the father (paternal).

Why does genetic deversity result in miosis one?
In prophase I there is a phenomenon known as genetic recombination or crossing over. Similar or homologous chromosomes get together to form a structure known as a tetrad. Two chromosomes (of the four= tetra) are originally from the parental sperm and the other two chromosomes are from the maternal source. Exchanging the DNA from one chromosome to another mixes the genes on these chromosomes so that after crossing over each chromosome is a mixture of maternal and paternal genes.

True. In humans, each pair of the 22 maternal autosomes has a homologous paternal chromosome, meaning that the chromosomes are similar in terms of size, shape, and genes they carry. This ensures that genetic information from both parents is represented in the offspring's genome.
What are chromosomes with same size and shape?
Chromosomes that have the same size and shape are called homologous chromosomes. These chromosomes carry the same genes, although they may have different versions of those genes. Homologous chromosomes are typically found in pairs, one inherited from each parent.

What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
How can a genetic disorders as Turner syndrome occur?
Going down to the cellular level, it occurs in meiosis when chromosomes fail to separate (nondisjuction). We get a set of chromosomes from our paternal side and the other set from out maternal side. For example, one of the gamete that may have came from our maternal side contains no chromosomes , O, when it should contain that chromosome x while from our paternal side we get a gamete containing the x chromosomes. This results in a XO, a sterile female when the normal sex chromosomes are XX or XY. -or- nondisjunction
The Probability that a male inherited his Y chomosome from his maternal grandfather is?
The probability that a male inherited his Y chromosome from his maternal grandfather is 0%. This is because males inherit their Y chromosome exclusively from their father, who passes it down from his own father (the paternal grandfather). The maternal grandfather contributes to the genetic makeup of his daughter's offspring through the X chromosome, not the Y chromosome.
How many chromosomes are created during the first division of meiosis?
Meiosis begins when a cell's chromosomes are duplicated by a round of DNA replication. This leaves the maternal and paternal versions of each chromosome, called homologs, with an exact copy known as a sister chromatid attached at the center of the new chromosome pair. The maternal and paternal chromosome pairs then become interwoven by homologous recombination, which often leads to crossovers of DNA from the maternal version of the chromosome to the paternal version and vice versa. A spindle fiberbinds to the center of each pair of homologs, and pulls the recombined maternal and paternal homolog pairs to different poles of the cell. The cell then divides into two daughter cells as the chromosomes move away from the center. After the recombined maternal and paternal homologs have separated into the two daughter cells, a second round of cell division occurs. There, meiosis ends as the two sister chromatids making up each homolog are separated and move into one of the four resulting gamete cells. Upon fertilization, for example when a sperm enters an egg cell, two gamete cells produced by meiosis fuse. The gamete from the mother and the gamete from the father each contribute half to the set of chromosomes that make up the new offsping's genome.
