How many chromosomes would be in a zygote if the bird has 30 chromosomes?
A zygote is a fertilized egg cell, so it is diploid and thus has a full set of DNA. If the adult has 30 pairs of chromosomes, the zygote would have 30 pairs. If there are 30 chromosomes, then the zygote will have 60 (30 from the mother and 30 from the father). It comes down to whether you meant individual chromosomes or pairs of chromosomes.
What happen to chromosomes as the zygote continues to divide?
as a zygote continue to divide the chromosomes keep producing
How many chromosomes human zygote possess?
46 23 from each parent...unless there is a mutation. Hi sorry to but in, but i was just wondering. If a human zygote contains 46 chromosomes and then total chromosomes they have is 46. Then if a mouse has 40 chromosomes would it's zygote be 40 as well? I have Biology homework and i was just wondering. Thanks!
If there is 10 chromosomes how many zygote?
A zygote is the combination of the half DNA data from both "parents" and if each have a total of 10 then the Zygote receives 5 from each parent and ends up with the same as its parents' number of chromosomes.
Trisomy-21 results from a mutation to the chromosomes in?
Gametes
How many chromosomes does a zygote have and a gamate have?

Where are the chromosomes in the zygote?
chromosomes are present in the nucleus of zygote.
How many chromosomes does s fruit flies zygote have?
8 chromosomes

How many Chromosomes does the zygote contain?
46 I think
How many sets of chromosomes does a zygote have?
there are 23 sets
A human egg cell has 23 chromosomes. How many chromosomes will a human zygote have?
46
Does a zygote have double or triple the number of chromosomes that a gamete has?
A zygote has twice the amount of chromosomes as a gamete.

What part of the body is involved in Trisomy 21?
The root of Trisomy 21 is within the chromosomes of the body cells.
