Answer:

A XY or XY gamete fuses with a normal gamete (X or Y)

Explanation:

Meiotic nondisjunction is the phenomenon whereby chromosomes fail to separate during meiosis I or II. Meiotic nondisjunction leads to the formation of abnormal gametes I.e. gametes with additional or missing chromosomal piece.

The fusion of these abnormal gametes produced by nondisijuction with a normal gamete (X or Y chromosome). This leads to a condition called ANEUPLOIDY, which is a chromosomal disorder. In the case od Calix, XXY is an ANEUPLOIDY state that could have resulted because there was a fusion between a XX gamete and Y gamete or XY and X. The XY or XX gametes are produced as a result of nondisijuction.

Answer:

1) Refrigerate or freeze

If you freeze or refrigerate the food, the bacteria or whatever organism growth will slow down in the food by a Greta amount due to the coldness. Refrigerate might be a temporary food soteage for like a week or 2/ month max. While freezing will just freeeze the bacteria and mold on the food which can be stored up to 3- 12+ months even. But then again it will be most likely flavorless by the end or have no nutrients value. You can stores mik in the freezer for a while but its not recommended to taste, same for other thing syou usually see in the fridge, eggs/ vegetables/fruits/ milks/ yogurts/ etc.

2) No moisture, no water of any kind (drying in the sun or salted)

So every living thing we know of needs water. Including bacteria and mold. Without water, theres no place to thrive. No place to thrive means no bacteria and food is safe for a good amount of time. Dried foods can last a really long time, sure some types are really unpleasant but its edible. But you can’t techincally “dry” meat since it will be A whole nest for flies before it even reaches the halfway mark. You can slat it which will lessen he time but still really efficient. Salt absorbs water and breaks down any type of Stuff. Its like a mini acid.

3) Canned good and no air access (Pressurized/ controlled container)

This is done by putting all your favortie food in a metal container. With no air access, the bacteria or mold in the food already in can’t escape and new ones can’t get in. THe can then is boiled to a certain tempature where then the bacteria dies. Now the food can even be perishable stuff like meat (most common fishes), fruits and even a nice can of liquid soup. Nothin g can get in. Nothing can get out but nothing CAN get out becuase eveythign is dead. Canned food can last REALLY LONG, good for long term expeditions without a fire or food.

Many genetic disorders of humans are caused by multiple alleles. recessive alleles. drinking during pregnancy. a mutation that o
MrMuchimi

The answer is recessive alleles. Generally, a recessive allele is the form of a gene that codes for a non-functional protein. When an individual inherits recessive allele for a gene from both parents, then they are more likely to suffer a disorder that is attributed to lack of the respective functional protein. Often the heterozygous individual will not bear the disorder even though they carry the recessive allele. This is because the dominant allele is able to mask the recessive allele by producing a functional protein.
