The four types of alterations of chromosome structure are deletion, duplication, inversion, and reciprocal translocation. Deletion is the loss of one or more nucleotides from a gene by mutation; the loss of a fragment of a chromosome. Duplication is repition of a part of a chromosome resulting from fusion with a fragment froma homologous chromosome. Duplication can result from an error in meiosis or from mutagenesis. Inversion is a change in a chromosomeresulting from reattachment of a chromosome fragment to the original chromosome, but in a reverse direction. Mutagens and errors during mesosis can cause inversions. Translocation is the attachment of a chromosomal fragment to a nonhomologous chromosome.

What are 2 possible end results of meiosis?
There could be 4 daughter cells with half the chromosomes as the original. Another outcome is crossing over in which one allele from one chromosome changes positions with an allele from another chromosome.
On which chromosome is the defective gene located in Hurler's syndrome?
chromosome 4
What are the 3 main types of adaptation?
The two main types of adaptations are structural (physiological) and behavioural.Structural adaptations include features such as bipedalism, jaw and tooth structure, opposable thumbs, position of the eyes and ears, electroreception, webbed feet, beak size and shape for birds, etc.Behavioural adaptations include behaviour such as being nocturnal or diurnal, herding, hunting in groups, to name a few.
How many chromosomes are in a homologous pair?
in a homologous chromosome there are two chromosomes ( a chromosome and a sister chromosome)
4 chromosome mutations?
They include: trans-location, deletion, duplication and inversion. A chromosome mutation is an unpredictable change that occurs in a chromosome.
