What else can I help you with?
Does the number of chromosomes determine how complex an organism is?
No there isn't. Humans are much more complex than a fern, yet the Adder's Tongue Fern has 1262 chromosomes and a human has only 46. It also doesn't work the other way either (more complex organisms having less chromosomes) for fruit flies have 8 chromosomes and dogs have 78. Also, chimpanzees have the same number of chromosomes as potatoes and, surely, they are on different complexity levels.
What is the types of human chromosomes in a karyotype?
Most chromosomes will make up a karyotype. It is important that you list a little more information to answer this question.
What is the maximum number of chromosomes ever observed in a human individual?
Oh, dude, the maximum number of chromosomes ever observed in a human individual is 92. Yeah, that's like double the usual 46. It's a rare condition called tetrasomy, but hey, more chromosomes, more fun, right?
How many pairs of chrosomes do humans have?
There are a total of 23 pairs (22 chromosome pairs, plus another pair determining sex) for a total of 46 chromosomes for a normal human being. There are various chromosomal abnormalities in which an individual may have more than (trisomy) or less than (monosomy) than 46.
Why are individual chromosomes more difficult to see during interphase than during mitosis?
During interphase, individual chromosomes are more difficult to see because they are in a less condensed state and are spread out within the nucleus. In contrast, during mitosis, the chromosomes are highly condensed and tightly packed, making them more visible under a microscope.
What is the process call when a human cell may have more or less than 46 chromosomes as a result of nondisjunction?
Chromosomes fail to separate during cell division (its in the lesson)
A human cell may have more or less than 46 chromosomes as a result of nondisjunction a process in what?
A human cell may have more or less than 46 chromosomes as a result of nondisjunction, which is a process that occurs during cell division where chromosomes fail to separate properly. This can lead to an incorrect number of chromosomes in the resulting daughter cells.
Why do older human eggs have more of a chance of chromosomes not dividing properly?
The older human eggs have more chance of chromosomes not dividing properly because of the chromosomal abnormalities in their eggs.
What describes the relationship between the number of genes and the number of chromosomes in human skin cells?
There are more genes than chromosomes in skin cells.
Do chromosomes have the same or different genes?
There are many more genes than chromosomes. The Human Genome Project currently has identified about 20,000 protein-coding genes, while there are only 46 chromosomes in the human genome.
Do more-complex organisms always have more chromosomes than simpler organisms do.?
Chromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.
How would human population be different if crossing over didn't happen during meiosis?
There wouldn't be any variety in the human population. Everyone would look more or less the same. This is because crossing over in meiosis allows the chromosomes to exchange genetic information to ensure that each daughter cell is unique and therefore, when reproducing, each person is also unique.
Whether each and every human cell posses 46 chromosomes?
no, normally humans do have 46, but certain mutations or genetic disorders can result in more, less, or fused chromosomes. the most common example of missing chromosomes is down's syndrome. when someone has an extra chromosome(s) it's called polyploidy. i can't tell you too much about fused chromosomes.
How many chromosomes do human have in prophase?
Humans have 46 chromosomes in prophase, which consists of 23 pairs of chromosomes. During prophase, the chromosomes become more condensed and visible as they prepare for cell division.
How many set of chromosomes dose human have?
It is because with only 2-3 pairs of chromosomes we would have much less variability (Variability is critical for the existence of a population;less variability, less resistant population). Why more variability? Because we have 23 pairs of chromosomes but they are not two exactly same sets of chromosomes.
How many chromosomes does a human cell that has been produced by the process of meiosis have?
After meiosis 2 in human cells are 23 chromosomes. Meiotic division occur only in reproductive cells because when spermatozoid and ovum combine they form again 46 chromosomes(23 pairs of chromosomes).
Which part of the human cell controls how the cell will grow?
nucleus.nucleolus and chromosomes to be more specific.
