Phosphatidylethanolamine is located at the :

Gene for the fungal resistance is found in the cytoplasm. If a susceptible female and resistant male are crossed then progeny will exhibit:

Inversion leads to crossover suppression because:

After meiosis, the 20% gametes are recombinant for two genes. The distance between the two genes will be:

A plant with genotype r+h+/ r‐h‐ was test crossed. Out of the total 280 progenies, 260 are r+h+/ r‐h‐ and r‐h‐/ r‐h‐. Then the recombination frequency will be:

The distance between the two genes ‘A’ and ‘B’ is 10 cM. What is the chance of getting a progeny with genotype Aabb, if  AaBb is test crossed?

The recombination frequencies between three genes x, y, and z are as follows: x – y = 2.6%, y – z = 1.4% and x – z = 1.2%. Then the gene order is:

Yeast with petite colony when crossed with wild type, generates no petite colony were formed. The most probable mode of inheritance is:

An allele has different effects depending on whether it was inherited from the father or mother. This is most likely due to:
