How do chromosome mutations affect an individual?
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
Which is more complex chromosome or gene?
A chromosome is more "complex" than a gene.:)
What various types of genetic material in order from simplest to most complex?
nucleus → chromosome → gene
List these in order from smallest to largest chromosome gene cell?
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
Which Chromosome has the trait For Blue Eyes?
Chromosome 19 has a blue/green gene. Chromosome 15 has a brown/blue gene. The genetics of eye color are more complex than realized previously, and more than one gene is involved in determining eye color.
Why are traits controlled by recessive alleles on the X chromosome are more common in males than in females?
Males only have one X chromosome, so even if the gene on that chromosome is recessive there is no other gene that could dominate it. Females have two X chromosomes, so if the gene on that chromosome is recessive there is still a chance that the gene on the other chromosome could be dominate and override it.
Gene is it the same as a chromosome?
no, the gene is not actually the chromosome but a part of chormosome...
What is the sry gene?
The SRY gene is a gene on the Y chromosome required for the development of testes. It stands for Sex determining Region on Y chromosome.
What chromosome is the HBB gene on?
chromosome 11
Gene A occurs on chromosome 5 gene B on chromosome 21 Therefore these two parts of a chromosome cannot be what?
alleles
Which chromosome contains the sex gene?
chromosome 1 chromosome 1
Whats a change in gene or chromosome?
A change in a gene or chromosome is called a: Mutation
