Answer 1

Question : why do daughter cells differ genetically from parent cells after meiotic division?

Answer:

Meiosis also known as reduction cell division is a kind of cell division that results in the production of haploid cells from a diploid cell.

it involves two phases Meiosis 1 and Meiosis 2

again they have sub phases

Meiosis 1-

•Prophase 1

•Metaphase 1

•Anaphase 1

• Telophase 1.. same for meiosis 2

meiosis 1 is longer and complex than all the subphases

it has 5 phases

leptonene , Zygotene, Pachytene , Diplotene,Diakinesis

leptotene - in this stage chromosomes become compact in size

Zygotene - in this stage homologous chromosomes start pairing together and a complex structure is called synaptonemal complex forms. the synapsed chromosomes are called bivalent

so stages will folow one after another, for more info u can read in book /internet

now let's dive in to your question

Pachytene - this stage is responsible for the difference in genetic constitution of parents and their offsprings.

so the thing is the four chromatids of each bivalent become distinct and appear as tetrads .

Recombination occurs now which is the exchange of genetic material between homologous chromosomes due to a process called crossing over between non sister chromatids
