Non separation of chromosome during meiosis is known as
Inversion
Crossing over
Linkage
Non-disjunction
The term gene was coined by
Bateson
Von Rendon
Gregor Mendel
All of these
The percentage of crossing over will be more if
linked genes are located far apart from each other
linked genes are located near to each other
both of these
none of these
Complementary genes show the ratio of
9:7
9:3:4
13:3
All of the above
Fails to clot Recombination of the alleles of the two genes A and B following crossing over will hypothetically results in four allelic recombination. In the absence of crossing over two parental combination would be formed like
AB and ab type
Ab and Ab type
aa and aB type
AB, ab, Ab, aB type
The qualitative trait is
Blood group in man
Eye colour is Drosophilia
Height in Pisum sativum
Seed storage protein in wheat
The theory of Natural selection was proposed by
Mendel
Darwin
Weismann
Hammerling
The most popular significant breeding method for cross pollinated crops is
mass selection
recurrent selection
both 'a' and 'b'
Which is the example of incomplete dominance ?
4 O' clock plant
Garden pea
Sweet pea
Coat colour in mice
