GENE LINKAGE
Every organism possesses numerous characters controlled by thousands of genes,
but the number of chromosomes is limited. .Therefore, each chromosome must carry
many genes on it. All the genes located on the same chromosome are linked to each
other. This phenomenon of staying together of all the genes of a chromosome is called
linkage. Gene linkage is a physical relationship between genes. A chromosome carries
its linked genes en bloc in the form of a linkage group. The number of linkage groups
corresponds to the number of homologous pairs of chromosomes. Man has 23 linkage
groups. Genes for colour blindness, haemophilia, gout etc form one linkage group on
human X - chromosome. Similarly, gene for sickle cell anaemia, leukemia and albinism
make another linkage group on human chromosome 11. Linked genes whose loci are
close to each other do not obey Mendel’s law of independent assortment, because
these cannot assort independently during meiosis. Gene linkage also minimizes the
chances of genetic recombination and variations among ofspring.

Amazing ap k lec bohat achy hoty hen points k form me learn kerna easy o jata

[@saim568]

God bless u for spreading knowledge...

[@ShahidUllah-hz7eo]

Sir 23 linkage group hoty Hain , number of linkage group is equal to number of homologous pairs in a organism

[@imranfarooq2677]

Hn Gg y equal hote is k

So helpfull

[@user-gn4ym6op4w]

Sir there are not 46 linkage groups in man, there are 23 in man

[@sabahameed5974]

Sir crossing over ka lecture upload ni keya ap na

[@Quran.recitation.336]

Sir humans main 23 gene linkages hotay h kiun Kay on k pairs bhi 23 hi hotay h.i guess

[@anjumfarheen3359]

3 MCQ samj nai aaya.. breaking occurance so, how is the ans is crossing over.. Inherited ???

[@saim568]

Zbrdst

[@khan_kainat]

Sir Cross over pr vedio bna dn plz

[@shakirzaman4832]

Salam are these linked genes are genetically transfer form parents?

[@ALIACADEMYAR7]

Yes

[@arssims8354]

Sr mera ek qs book main line homologous chromosomes pairs correspond to linkage group not individual chromosome tou agar 46 chromosome houn gy tou linkage group 23 hoon gy na 10:47 u said if 46 chromosome 46 linkage group HOW??? Man has 46 chromosomes but 23 linkage group

[@ziaulhaq4269]

Right , I was here to say the same thing

[@ziaulhaq4269]

And number of genes are not in crores ,but total number of genes in human DNA are about 23000

[@Trending_luna]

Sir g

[@Harsh1403.]

sir is topic per hindi mai note bnaker bta dijiye

[@Laparganjikhn]

Our book has 23 linkage groups.

[@CruelGamerFTW]

It is because of homologous chromosomes

[@MuhammadAshraf-vd8fe]

Bcz last time mcqs nahi aye thy in chapters ma sa plz confirm kr dyn

[@ALIACADEMYAR7]

Ye syllabus me shamil ha

[@shehzanakiran8038]

46 chromosomes posses 23 linkage grop... do correct

[@ALIACADEMYAR7]

Yes
