If there is a lack of chromosomes, then the full genetic structure of a human being cannot be reproduced because a human is made up of forty-three chromosomes (twenty-three from each parent) and if one is missing, there will only be forty-five, which will not reproduce a human being.
What else can I help you with?
What are the key differences between prokaryotic chromosomes and eukaryotic chromosomes in terms of structure and organization?
Prokaryotic chromosomes are simpler and circular, found in the cytoplasm, while eukaryotic chromosomes are more complex and linear, found in the nucleus. Eukaryotic chromosomes are organized with histone proteins into chromatin, while prokaryotic chromosomes lack histones.
Predict what might happen to each daughter cell if all the chromosomes moved to only one side during anaphase?
don't know : D haha one of the daughter cells would lack chromosomes while the other one would have too many. In the end they would probably both be mutants and either die or have serious issues. I don't know for sure. Just a guess.
What stage in mitosis does the chromosomes uncoil happen?
During the telophase phase, the chromosomes begin to uncoil. There are six phases with mitosis and telophase is number four.
Does recombination happen when chromosomes get tangled?
No, recombination is a specific process where genetic material is exchanged between homologous chromosomes during meiosis. When chromosomes get tangled, it may lead to genetic mutations or chromosomal abnormalities, but recombination is a separate biological mechanism that occurs to generate genetic diversity.
What are chromosomes that are of the same size and function and the centromere is at the same location yet are not homologous?
These are known as isochromosomes. They consist of two identical arms due to an abnormal chromosome division where the centromere is duplicated. Despite their similarity in size and centromere position, they lack the genetic diversity found in homologous chromosomes.
Is colorblindness caused by a lack of chromosomes?
no
Is huntingtons disease due to lack of chromosomes?
No, the Huntington's disease is inherited from either the mother or father. It's genes not a lack of chromosomes.
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
What will happen if you have excessive chromosomes in your body?
Nothing serious will happen.
What happen to chromosomes during meiosis?
half of each parents' chromosomes go to the offspring
What phase does the division of chromosomes happen?
Chromosomes will line up in metaphase and in anaphase they will split apart.
Is breast cancer do to a lack of chromosomes or extra chromosomes?
Neither. Breast cancer is the over growth of cells due to hormones or genetics.
What are the key differences between prokaryotic chromosomes and eukaryotic chromosomes in terms of structure and organization?
Prokaryotic chromosomes are simpler and circular, found in the cytoplasm, while eukaryotic chromosomes are more complex and linear, found in the nucleus. Eukaryotic chromosomes are organized with histone proteins into chromatin, while prokaryotic chromosomes lack histones.
What would happen if homologous chromosomes paired with non-homologous chromosomes in meiosis 1 instead of the matching homolog?
good question!
How many chromosomes does a tomato have?
A tomato would happen to have 12 pairs of chromosomes, therefore it has 24 chromosomes. I figured that by multiplying 12 by 2.
Is cleft lip due to a lack if chromosomes or extra chromosomes?
Cleft lip is typically not caused by a lack or extra chromosomes. It is often a result of a combination of genetic and environmental factors, such as maternal smoking or certain medications during pregnancy. It is a congenital condition where the lip does not form properly during fetal development.
What might happen if an egg cell received two X chromosomes during meiosis instead of one?
The offspring could have three X chromosomes or two X chromosomes and a Y chromosome.
