An extra chromosome will produce an aneuploidy. It may have severe consequences on the resulting zygote.
<h3>Aneuploidies and chromosome abnormalities</h3>
The term 'chromosome abnormalities' refers to different types of problems that occur in meiosis which are associated with the disjunction of chromosomes.
The most common chromosomal abnormality is called aneuploidy, which means an abnormal number of chromosomes.
Aneuploidy is caused by the presence of an extra or due to the lack (missing) of a chromosome during meiosis.
For example, a trisomy is an aneuploidy due to the presence of an extra chromosome (three copies of the same chromosome instead of two).

Answer:
Homolog genes with sequence identity often exhibit differences in length associated with size variations in the intronic sequences
Explanation:
In eukaryotic organisms, genes are composed by 1- coding sequences (i.e., exons) that are transcribed into precursor mRNAs, and 2-noncoding regions (or introns), which are not transcribed but contain sequences involved in the control of gene expression
Cool air over any pole will either cause a voluntary crash on the floor/ collapse, but it all depends on the strength of its placement in the ground. A weak placement could easily make it collapse, or it could stay still (with perhaps a flag waving in the direction of the wind, on top) of kept firmly onto the ground.
It depends on how you look at evolution. I would say B would be my answer. but it also depends on the course you take. Mine was a Christian based course. So I learned that evolution wasn't a thing.
Answer:
cephalochordates
Explanation:
Cephalochordata is one of the subphylos of the phylum Chordata with about 30 species. Cephalocords are small (centimeter long) animals, thin, laterally flattened (like the body of fish), transparent and live buried in sandy substrates leaving only their heads apparent. They are currently represented by the amphioxes. Cephalocords are the group of invertebrates that is most related to vertebrates.
The body of the cephalocordates is composed of longitudinal (horizontal) muscles that are divided by blocks called myotomes. The notochord holds in adults giving a stronger structure to the body.
