Question

question 2
which of the following choices represents the genotype of an individual diploid organism?
bbccdd
bcd
bcd
bbcd

Explanation:

A diploid organism has two sets of chromosomes. Each gene locus has two alleles. In the genotype, for each gene, there should be two alleles (e.g., \( Bb \) for one gene, \( CC \) for another gene, \( dd \) for the third gene). The option \( BbCCdd \) has two alleles for each of the three genes considered. The other options (\( BCd \), \( bcd \), \( BbCd \)) do not have two alleles for each gene - \( BCd \) and \( bcd \) seem to represent haploid (one - set) or incorrect allele - number combinations, and \( BbCd \) also has an incorrect number of alleles for a diploid at the third gene (should be two alleles like \( dd \) in \( BbCCdd \)).

Answer:

\( BbCCdd \)
