DEFINITION
(Phenetics...)
Type of classification based on analysis of maximum taxonomic data of equally weightage characters by mathematical method aur computerised methods and in which individuals are group on the basis of similarity.
PRINCIPLE OF NUMERICAL TAXONOMY
●The more characters the better classification will be
●Every characters should be given equal weightage
●Based on phenetic similarity
METHOD
●Selection of taxa (otus)
●Selection of characters or traits
●Cluster analysis via computer software
●Determination of taxonomic relationship between Otus
●Classification on the basis of over all similarity
SELECTION OR CHARACTERS
●Character used is UNIT CHARACTER.
●Two types
•BINARY CHARACTERS only two states e.g. present absent
In coding (+or-)
•MULTISTATE CHARACTERS
Three aur more state may be qualitative aur quantitative.
E.g colour (quality)
Number(quantitative)
RULES
●Included all part
● at least 50 characters
●all stages characters
CHARACTERS WIEGHATGE
●Equal weightage
●Successive weightage (homoplasy aur unique)
CLUSTER ANALYSIS
●computer shorts out the OUTs according to similarity a/c to number of characters in common.
●Software produces phenogram that is dedogram which shows relationships between the taxa.
Sir aap bahut achha smjhate ho 👍
Bilkul sahi
Your teaching is superb
Best explanation .
Thanku thanku so much sir aap bahut acche se smjhte ho sir 🥰
Thank you so much 💓
Tank's so much Sir 🙏🙏🙏🙏🙏🙏
Very good
Thanku so much sir 👌
Thanx sir😊
Sir app ne sab kuch acchai se explain kiya but selection acchai se samaj nhi ayaa
Thanks you so much sir
Thank you sir
Sir please make a video on how to prepare taxonomcal key
Chemistry BHI padhaye sir aap
Sir MCQ hoge exam MCQ karayiye na
Sir, what to write in answer to the question "what is OTU?" (2 marks question)
Operation taxonomic units
Sir isko note bana sakte hai
Sir ye kis University ka syllabus hai?
🙏🙏
