What results form the process of crossing-over during prophase 1?
I do GP Biology (9th year here), and I'm on the quiz "Week 13-Meiosis: The Life Cycle of S-x Cells". I got the question What happens during crossing over? The answer was "homologous chromosomes trades pieces of DNA." Hope this was the answer you're looking for!
How similar are two people with respect to chromosomes genes and alleles?
Two individuals can be highly similar in terms of chromosomes, genes, and alleles if they are closely related, such as siblings. They will share a significant portion of their genetic material due to inheritance. However, unrelated individuals will have more differences in their genetic makeup, with variations in chromosomes, genes, and alleles.
How many chromosomes does a normal individual have?
The average human has 24 chromosomes, and autistic people have two copies of the 23rd in place of the 24th
How many chromozones do people have?
People typically have 46 chromosomes in their cells. This total comprises 23 pairs of chromosomes, with one set inherited from each parent.
How many chromosomes are present in each cell in this human?
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
What is an example of prophase?
An example of prophase is the first stage of mitosis or meiosis where chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

People with a Down syndrome have 27 chromosomes?
yes, whereas normal people have 23 pairs of chromosomes

Can you get Down syndrome from your father?
you can not "get" down syndrome, you are either born with it or you are not born with it. there has only been one documented case of a male with down syndrome fertilizing an egg and it resulted in a miscarriage. down syndrome is not something you can catch. it is a chromosomal defect, a fluke of nature. it is also known as Trisomy 21. typically advanced people are born with 46 pairs of chromosomes. each pair has only two chromosomes. people with down syndrome have an extra chromosome pair of the 21st set of chromosomes. so people with down syndrome have 47 pairs of chromosomes. Three to four percent of all cases of trisomy 21 are due to Robertsonian Translocation. In this case, two breaks occur in separate chromosomes, usually the 14th and 21st chromosomes. There is rearrangement of the genetic material so that some of the 14th chromosome is replaced by extra 21st chromosome. So while the number of chromosomes remain normal, there is a triplication of the 21st chromosome material. Some of these children may only have triplication of part of the 21st chromosome instead of the whole chromosome, which is called a partial trisomy 21. hope this helps your question. =]
What is meant by '' crossing over'' in terms of cells in your body?
Crossing over refers to the exchange of genetic material between homologous chromosomes during meiosis. This process increases genetic diversity by creating new combinations of genes, leading to unique traits in offspring. It helps in the formation of gametes with genetic variation.
How many chromosomes are present in each cell in this human?
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
What chromosomes are found in gays and lesbians?
People have the same number of chromosome pairs, no matter if they are gay, bi, straight, asexual, or anything else!
How many chromosomes do colorblind people have?
2
Where did people follow the wooly mammoths to during the ice age?
Because they needed food and material to make clothes and blankets
What type of chromosome do humans have?
Diffrent people have diffrent chromosomes.
How many chromosomes are in a genome?
The number of chromosomes in a genome varies depending on the species. For humans, there are 46 chromosomes (23 pairs) in a genome. Each chromosome contains thousands of genes that carry genetic information.
