Can a male have the same X chromosome as his paternal grandfather?
No, he cannot.He cannot even have the same X chromosome as his father.The reason is that a male has an X and a Y chromosome in his genome. The Y must come from Dad, because Mum does not have any Y to pass on!So the X must come from Mum.Now looking at grandparents: a male's father supplied the Y, and father's Y came from the paternal grandfather. So the paternal grandfather's contribution must be the Y chromosome.The male's Mum has two X chromosomes, one from the maternal grandfather, and one from Mum's Mum.
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.
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.
What happens in anaphase I but does not happen in anaphase II?
In anaphase I of meiosis, homologous chromosomes are separated and move to opposite poles of the cell, while sister chromatids remain joined. This step does not occur in anaphase II, where sister chromatids are separated and move to opposite poles.
What two things happen during meiosis?
chromosomes split and the cell divides The above mentioned two things happen in mitosis also, so the correct answer would be - 1. Exchange of chromatin material by crossing over and 2. Reduction in the number of chromosomes to half.
What phase of meiosis does independent assortment happen?
The independent assortment happens in the following steps in the meiosis 1. During the Pachytene stage of prophase I of the meiosis one the genes in the homologous chromosomes mixes randomly among each other by a process called crossing over and largely responsible for the variation between the siblings. 2. Metaphase 1 : The random assortment of bivalent takes place. 3. MetaphaeII : The chromosomes move randomly to the equator

What is the opposite word of happen?
the opposite of "happen" is "dematerialize"
When does independent assortment occur in mitosis?
Independent assortment does not happen in mitosis, it happens in meiosis. In metaphase I of meiosis, synapsed homologous chromosomes align independently of one another along the metaphase plate. That is to say, one aligning in a certain fashion has no effect on another aligning in a certain fashion. In mitosis, chromosomes are exact copies of the parental cell's and independent assortment is a method of achieving genetic variation, which does not happen in mitosis.
What will happen if you have excessive chromosomes in your body?
Nothing serious will happen.
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
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.
Explain why prophase is the longest phase in mitosis?
because the most things happen in it. centrioles grow, spindle fibers arrange on chromosomes, and the cell grows exponentially.
What the opposite of happen?
Well, I can tell you that the opposite of happen is spelled in two ways: 1) Dematerialize or 2) Dematerialise.
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.
