Which statement is not an accurate description of meiosis?
sesenic [268]
<h2><u>Full Question:</u></h2>

Which statement is not an accurate description of meiosis? A) Meiosis produces offspring that are genetically diverse. B) Meiosis produces offspring that are identical to the parent. C) In sexual reproduction half of the genetic material comes from the father (sperm) and half of the genetic material comes from the mother (egg). D) Meiosis decreases the number of chromosomes by half so that when a sperm fertilizes an egg, the resulting zygote has the correct number of chromosomes

<h2><u>Answer:</u></h2>

Meiosis produces offspring that are identical to the parent.

Option B.

<h3><u>Explanation:</u></h3>

Meiosis is a type of cell division that is generally seen during then gametogenesis of the higher animals where the diploid cells become haploid, thereby reducing the chromosome number of cell to half. This meiotic division ensures that the gametes produced are haploid in nature, so that when they fuse the zygote becomes diploid. And the meiosis also involves the steps like  and indepencrossing overdent assortment which ensures that the offsprings produced are not identical to each other or with the parent as well. So the statement that meiosis produces identical offsprings is false.

CAN ANYONE HELP WITH THIS SCENARIO :(
Zanzabum
You can write the argument but I’ll list some stuff to help you write it out

•These warnings should be provided for the safety of people who buy their products because if they’re not, then the company should be held accountable for the deaths and or injuries.
This is because if they’re selling products without safety regards, they are selling dangerous products to people including children, which is Illegal.
The dad on the other hand did nothing illegal. He simply bought this product feeling safe to leave it with his child because there were no hazards or warnings of any kind, and BAM! It killed his child.
Therefore leaving the death of the child in the Companies hands.

•if their product does not contain a warning/hazard ( choking )of some sort, they’re technically saying that the child does not need to be supervised while being with that toy.
The dad felt no need to supervise the kid with the toy because there were no warning signs provided on it.
Therefore, leaving the safety in the playskool’s hands.

The dad did nothing wrong here. Since there were no warnings provided. As warnings are to warn those of danger who buy the product. Since no warning was clearly provided, then the safety of his child was not held towards him.

The company on the other hand, failed to do their job which was simply putting safety reguardes on children’s toys. Since that wasn’t provided, then that makes them (the greatest of the product without safety hazards) the killer of the baby.

- I’m sorry it’s so long and I tried but couldn’t think of anything else that would help defend the dad but I hope it helps you write your argumentative essay or whatever it is!
