Use the chromosome image where the letters represent genes t

Use the chromosome image, where the letters represent genes, to match the following statements with their answer. Smallest crossover frequency most likely to be separated by crossing over recessive possible genotype of resulting gamete dominant possible recombinant chromalid genotype.

Solution

1. Distance between genes on cromosome is Directly proportional to the Crossing over. More distance , more crossing over. So smallest crossing over frequency observed between R, M genes.

2. More distance between genes, they are easily seperated duering crossing over. F, G genes are more likely to be separated during crossing over

3. Those genes which are not expressed in Heterozygous condition are called Recessive genes. Here f, g, r, m are recessive alleles or genes

4. The meiosis products are called gametes. The possible gametes are: Fg, fG (Trans arrangement), RM, rm (Cis arrangement)

5.
