Difference between complete and incomplete linkage
can you explain the table 5.3 given on pg82,biology ncert book?
difference between complete and incomplete linkage
?
How is sex determined in human beings?
How did they explain linkage, recombination and gene mapping on the basis of their observations ?
Coloured and full = 45%
Coloured - shrunken = 5%
Colourless - full = 4%
Colourless - shrunken = 46%
From these data what would be distance between the two non allelic genes :
(1) 48 unit
(2) 9 unit
(3) 4 unit
(4) 12 unit

Q193. In a cross between individuals homozygous for (a, b) and wild type (+ , +). In this cross 700 out of 1000 individuals were of parental type. Then the distance between a and b is:
(1) 70 map unit
(2) 35 map unit
(3) 30 map unit
(4) 15 map unit
whatare complementary and supplementary genes?
Q.151. In maize, coloured endosperm (C) is dominant over colourless (C), and full endosperm (F) is Dominant over shrunken (f). When a dihybrid of generation was test crossed, It produced Four phenotypes in the following percentage :-
Coloured full - 41 %
Coloured shrunken - 9 %
Colourless full - 9 %
Colourless shrunken - 41 %
From this data, what will be the distance between two non-allelic genes?
(1) 48 units
(2) 5 units
