okay so there is a circle with >B >b \d D in it. its a diploid cell with two homologous pairs of chromosomes.
due to independent assortment, the possible allelic combinations that could be found in the gametes produced by the meiotic division of this cell would be?

im not sure. is it
A. Bb, Dd, BB, DD
B. BD,bD,Bd,bd
C. BbDd and BDbd

(B).



The organism has the genotype BbDd, so it produces 4 types of gametes, BD, Bd, bD, and bd. Every gamete must contain ONE and ONLY ONE from each pair of genes. A gamete must have 2 alleles, and no gamete can have 2 B alleles or 2 D alleles.

Homologous chromosomes are a pair of chromosomes that pair up for the period of meiosis to create gametes. each and each pair contains the genes for an identical style of characteristic on an identical region, in spite of the shown fact that the genes would code for something distinctive (brown hair vs blonde hair). Diploid is a cellular that contains 2 instruments of chromosomes, on an identical time as a haploid cellular in undemanding terms contains one set.

The answer is C.

You must have one (b) and one (d) whether they dominant (B) or recessive (b) in order to form an genotype.
