ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some
mihalych1998 [28]

Answer:

1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).

2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.

What are two diffrences between replication and transcription?
Ghella [55]
Replication - The action of copying or reproducing something.
DNA replication of producing two identical replicas of DNA from one original DNA molecule.

Transcription - First step to gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

1.) Transcription involved both DNA and RNA, whilst replication only involves DNA.
2.) Replication uses two identical replicas of DNA, whilst transcription is copied.
