Answer:
umm I can't understand this I'm very very sorry but please put me on the brainliest
Answer:
Both gene expression and DNA micro array study about the expression of gene during different stages of development.
Explanation:
The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.
DNA microarray assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.
Meiosis is needed for sexual reproduction, here chromosome number is halved, it provides for mixing up of genes.
mitosis is needed for growth, repair, replacement, asexual reproduction.
it maintains same chromosome number
If you are implying one these choices not needed for survival it would be parents only when you can survive on your own (I'm not that sure but I hope this helped the slightest but)
Answer:
Mother- XXH
Father- XHY
Explanation:
The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.
