Which period are chromosomes duplicated in?
During the cell cycle, chromosomes are duplicated during the interphase.
Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
When do chromosome duplicate themselves during mitosis?
In Mitosis, the chromosomes duplicate themselves. In Meiosis 1, they duplicate, however they do not duplicate in meiosis 2.
What happens to chromosomes and chromatin during each stage of mitosis?
IDK LOL at least i answered actualy i do when that happens u get pimples the size of a centimeter then to calculate it u must find what pie equals athen do this format. 12x(B to the second power times 4) subtract 923 :P good luck hehe...
What happens during the three phases if interphase?
G1: This is the first growth phase. The cell synthesizes proteins and produces cytoplasm organisms. S: This is the synthesis phase. The cell grows while it copies its chromosomes. G2: This is the second growth phase. The cell begins the assembly of the spindle.

What phase of mitosis do the chromosomes replicate?
Strictly speaking, the chromosomes are not copied during mitosis but already before cell division takes place. This phase is called INTERPHASE and is again divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). The replication of chromosomes only happens in the S phase.
What happens in meiosis during telophase II?
A total of four daughter cells form. *apex*
Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
How many chromosomes will the cell have during late second meiotic anaphase if the diploid chromosome number is 4?
2
What happens during the second trismester?

Why does turner's syndrome occur?
Going down to the cellular level, it occurs in meiosis when chromosomes fail to separate (nondisjuction). We get a set of chromosomes from our paternal side and the other set from out maternal side. For example, one of the gamete that may have came from our maternal side contains no chromosomes , O, when it should contain that chromosome x while from our paternal side we get a gamete containing the x chromosomes. This results in a XO, a sterile female when the normal sex chromosomes are XX or XY. -or- nondisjunction
Which animal has the largest number of chromosomes?
Butterflies have 380 chromosomes. Hermit crabs are in second place with 254.
