difference between complete and incomplete linkage?
what is the difference between chromosome and gene?
explain the table in NCERT which differentiates b/w the two, i found both of them to be the same then where is the difference?
How is sex determined in human beings?
can you explain the table 5.3 given on pg82,biology ncert book?
What is the difference between epistasis and dominance ?
which mendel's law of inheritance is universally accepted and without any exception.State the law.
In a linear chromosome, map distances between four loci are as follows: a-b-10, b-c-4, a-d-3, a-c-6. the expected cross over frequency between c and d is-
c) either 3%or 9%
d)4% to 12%
plz provide the solution

Why mendel chose only pea plant for his experiments?
WHAT IS PEDIGREE ANALYSIS? DO YOU SUGGEST HOW THIS ANALYSIS IS USEFUL
Assume that gene a and b are linked and show40% recombination. If ++ / ++ individual iscrossed with ab / ab, then types and proportionsof gametes in F1 will be :-(1) ++ 20% : ab 20% : +b 20% : a + 40%(2) ++ 50% : ab 50%(3) ++ 25% : ab 25% : + b 25% : a + 25%(4) ++ 30% : ab 30% : + b 20% : a + 20%
