The arctic fox has 50 chromosomes (25 per set), and the common red fox has 38 chromosomes (19 per set). These species can interb
Irina-Kira [14]

Answer:

The organism is sterile because parts of the chromosomes in the zygote will only have a  single set of chromosomes rather than the ideal pair. The arctic fox will produce gamates with 25 chromosomes (a single set) while the red fox will produce gametes with 19 chromosomes (another set). These gametes are supposed to fuse and have their chromosomes paired. However notice that the offspring will have (25 – 19) six (6)  unpaired chromosomes. This means that during the formation of gametes in this hybrid offspring, there will be an issue in meiosis I which will result in nonviable gametes.

BabaBlast [244]

The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.

This kind of squamous epithelial cells are slightly porous which allows the oxygen from the air to enter the blood in the capillaries of the lung. So the squamous epithelium is the epithelium in which the lining of the air sacs or alveoli occurs. Each alveolus is lined by the squamous epithelium.

So we can conclude that: The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.
