Question

During metaphase 1 of meiosis, homologouus chromosomes can orient thenselves such that one or the other will by chance go to a particular daughter cell in a process known as
a. segregation
b. independent assortment
c. crossing over
d. chromosomal inheritance

Answer 1

The correct answer to this question is B, mendel's law of independent assortment. If you flip a coin a million times you will get very close to 50% heads and 50% tails. The same thing happens to chromosomes in meiosis. They way the line up is completly random.

Answer 2

This is a bad question. It can either be A or B. It's definitely not crossing over nor chromosomal inheritance. Crossing over takes place during prophase I, and is when homologous chromatids swap genetic sequences. Independent assortment is the law that each chromatid will go to one daughter cell independently of the other chromatids (they are "sorted" into each daugher cell "independently".) But the process of the chromatids going to each daugher cell is called segregation (think about the 1950's in america where people were seperated). Chromosomal inheritance is a red herring, so it's not right. Chromosomal inheritance is basically the overall process of meiosis. So, C and D are definitely wrong, A or B are both right.

Moral of the story. This question is crap.

Answer 3

B) independent assortment
In metaphase, the chromosomes line up along the metaphae plate, and then separate thru independent assortment, sending one chromatid from each pair of chromatids to each daughter cell.

Answer 4

Crossing over is where two chromasomes cross their ends over one another, and detach from their end as they attach to the other's end. in this way, genetic coding is randomly created and therefore, children don't always look like their parents.

the Law of Independant Assortment states that different genes that codominantly code for one trait will be sorted independant of one another. So like, all your different genes for hair color would be sorted independant of one another's sorting. essentially, they all are sorted with no influence of one another.

The Law of segregation states that genes will be segregated r something.

I have no idea what that last one is. Think we learned a different term for it.

Answer 5

Most likely
c. crossing over

I've never heard any of the other terms in meiosis.

Answer 6

I'm pretty sure it's called crossing over-I haven't taken cellular biology in a while, but I got over 100% in it.
