How to Know When to Capitalize a Word?
Correct spelling is only the first step in writing any word or name. Make sure you follow the rules when it comes to capitalizing.
You will need: proper names, titles, academic titles, knowledge of parts of speech and degrees and designations.
__________
The rules for capitalizing job titles have to do with the order and use of the words, and occasions when a job title is part of the person's name.
__________
Use capitals to designate subject majors or academic disciplines only if they refer to a language, ethnic group, or geographical entity. Take classes in political science, for instance, but attend courses in Spanish and German.
Capitalize nouns in the titles of works, as well as pronouns, verbs, adverbs, adjectives, and subordinating conjunctions like "before", or "after". Prepositions of four letters or more follow this rule as well.
__________
Be aware that on book jackets, aesthetic prerogatives will sometimes override rules for capitalizing.
Stick to the upper case for all principal words and the first word and last word in document and report titles.
Choose to capitalize all major words, including nouns, pronouns, adjectives, verbs, and adverbs, in titles of musical compositions, television shows, and movies. Follow rules of capitalization and improve your grades and your writing.
Did you know? In 2008, language experts claimed some 3,000 of the world's almost 7,000 languages may be disappearing.
订阅后能看到列表,还能及时收到更新通知哦~Capitalize a person's title when it precedes their names, but not when it follows a proper name or is used alone, as in General Johnson, as opposed to Winston Johnson is a general.
The same rules apply to titles like "Doctor" or "Reverend", even though they are normally abbreviated before a name.
Add someone's academic degrees and professional designations to their name in writing, using capitals to emphasize those titles.proper name 专有名词
designate v.标出 designation n.名称,称号
e.g: Buildings are designated by red squares on the map.
Her official designation is Systems Manager.
precede v.在...之前
e.g: a type of cloud that precedes rain
apply to 适用于
e.g: Everyone thinks that the rule doesn't apply to them. 上传我的文档

牛的毛色有黑色和棕色,如果两头黑色牛交配生了一头棕色小牛,请回答:(1)牛毛的黑色和棕色在遗传学上叫______,其中______是显性性状(2)如果用B与b表示控制牛的毛色基因,写出上述两头黑牛及棕色小牛的基因组成:______、______、______.(3)上述两头黑牛交配繁殖生出黑色小牛的可能性是______.(4)如果用一头雄牛与多头雌牛(基因组成为Bb)交配,共出生20头小牛,全部为黑色,则此雄牛的基因型最可能是______.
第-1小题正确答案及相关解析
解:(1)牛毛的黑色和棕色,是同种生物牛的毛色不同,是同一性状的不同表现形式.因此,牛毛的黑色和棕色在遗传学上叫相对性状.
在遗传学上叫在一对相对性状的遗传过程中,子代出现了亲代没有的性状,这个新出现的性状就是隐性性状;控制该性状的基因就是隐性基因,亲代的性状是显性性状,亲代的基因组成是杂合的.因此如果两头黑色牛交配生了一头棕色小牛,表明黑色是显性性状,棕色是隐性性状.(2)通常用大写字母表示显性基因,小写字母表示隐性基因.如果用B与b表示控制牛的毛色基因,那么用B表示显性基因黑色,b表示隐性基因棕色.因此两头黑牛交配产生了一头棕色小牛.两头黑牛的基因组成是Bb,棕色小牛的基因组成bb.遗传图解如图:(3)从遗传图解看出,上述两头黑牛交配繁殖生出黑色小牛的可能性是75%.(4)雌牛含有一个控制棕色的基因b,但是在子代中没有表现出来,说明与之交配的雄牛其控制毛色的基因中没有隐性基因b,只有显性基因B,故此雄牛的基因型最可能是BB.
故答案为:(1)相对性状;黑色
(2)Bb;Bb;bb
(3)75%;(4)BB.
