what is necrosis in 12th question and pollen culture in 6th question?
NECROSIS-IT IS DEATH OF TISSUE,A LEAF TISSUE.DUE TO THE DEFICIENCY OF CA,MG,CU,K…..
POLLEN CULTURE- IT IS FORMATION OF NEW PLANTS BY USING POLLEN GRAINS……
These tests are really too helpfull.I have scored good marks in my tuition tests as I had appeared these tests before my tests in tuition.thanks a lot
Yeah really Good one….!
Must solve once in a day.
This is very helpful.
sir i read in a book that pure line breeds refer to homozygosity only. i have confusion in 8th question.
Thanks Shivani – The answer has been replaced as:
Pure line breeding – involves selection of individual plants at one or more stages in breeding.
Complete homozygosity – all the alleles at all loci are identical by descent and no heterozygosity at any locus.
