The B and C gene are very close to each other on chromosome

The B and C gene are very close to each other on chromosome 21 and therefore so tightly linked that no recombination ever occurs. If bC/bC crosses with Bc/Bc, followed by a cross between those offspring, what are the genotypes and phenotypes of the F2 generation?

Solution

Any process in diploid cells which generates new chromosomal combination not found in that cell.

In Meiosis, the procesa that generates haploid product of meiosis whose genotype is different from either of the 2 haploid genotype that constituted the meiotic diploid.

P Bc/Bc×bC/bC

F1 Bc/bC

F2 1Bc/Bc

2Bc/bC

1bC/bC
