其實這是我們讀書會要的東西,我準備第十五章,可是上次忘了整理共筆
今天和吃飯團很歡樂的回到系館已經8點了......和大家跑到8樓看書~
很歡樂的邊整理族譜邊整理筆記,原本要po在p2的
可是根據可靠情報表示,要賺p幣最好po在ptt~所以我來囉!

homologous pair 同源染色體
chromatid 染色分體
heredity 遺傳
dihybrid 兩性狀雜合體
embryology 胚胎學
zygote 合子
phenotype=>wild type <---> mutant type
SRY(sex-determining region of Y chromosome):
when it absense gonads develope into ovaries
sex-linked gene:a gene on a sex chromosome
linked genes:genes on the same chromosome
Duchenne muscular dystrophy: 1/3500 of males
progressive weakening of the musles and lose of coordination
individuals rarely past their early 20s
due to the absence of the dystrophin muscle protein
*the gene on the X chromosome
Hemophilia:sex-linked
the absence of one or more of the proteins reguired for blood clotting
bleeding will prolonged because a firm clot is slow to form
Barr body lies along the inside of the nuclear envelope
Down Syndrome
trisomy 21
characteristic facial features; short stature; heart defects;
susceptibility to respiratory infection; mental retardation
prone to developing leukemia and Alzheimer's disease
life span shorter than normal
the frequency of Down Syndrome increases with the age of the mother
some research points to an age-dependent abnormality in a meiosis check-
point that normally delays anaphase until all the kinetochores are attached
to the spindle
Aneuploidy of Sex Chromosomes
*Y chromosome carries relatively few genes
*X chromosome become inactivated as Barr body in somatic cells
XXY:1/2000(Klinefelter syndrome) males only
testes are abnormally small
the man is sterile
some breast enlargement and other female body characteristics are common
XYY:males only
only tend to be somewhat taller than average
XXX:1/1000
can't be distinguished from XX females
XO:1/5000(Turner syndrome)
phenotypically female, but sterile because their sex organs don't mature
providen with estrogen replacement therapy, they do develop secondary
sex characteristics
*only known viable monosomy in humans
cri du chat(cry of the cat)
deletion in chromosome 5
mentally retarded; small head; unusual facial features
has a cry that sounds like the mewing of a distressed cat
usually die in infancy or early childhood
Chronic myelogenous leukemia (CML)
a large portion of chromorsome 22 with a small fragment from a tip of chro-
mosome 9 produces a much shortened, easily recognized chromosome 22, called
the Philadelphia chromosome
-----------------------------------終於打完了----------------------------------
打了快一個小時~好累唷~
這一章我蠻建議大家回頭把普植實驗四重背一次的
有一些單字都會用到~~
大家要幫我挑錯字唷!因為我懶的校稿了.......
有錯的請推文說錯在哪,我會把它修掉~~~謝囉!
