Would a dihybrid cross between a heterozygous parent (BbSs) and a homozygous dominant parent (BBSS) end up as independently assorted genes? The results of offspring would be 100% dominant.

Answer #1

Answer -the dihybrid cross between heterozygous parent BbSs and homozygous dominant parent BBSS is as follows :

Parent genotype = BbSs. X. BBSS

	BS	Bs	bS	bs
BS	BBSS	BBSs	BbSS	BbSs
BS	BBSS	BBSs	BbSS	BbSs
BS	BBSS	BBSs	BbSS	BbSs
BS	BBSS	BBSs	BbSS	BbSs

The genotype of offspring are as follows

BBSS : BBSs : BbSS :BbSs

4:4:4:4

From above explanation it is concluded that, this dihybrid cross would not end up as independently assorted genes.

Because the ratio for dihybrid cross for independent assortment of genes is 9:3:3:1

Therefore the ratio of genotypic characteristics does not match with 9:3:3:1.

Genes W, Y, Z assort independently and are dominant over their corresponding alleles w, y, z. You conduct an experiment where you set up a cross between two individuals heterozygous for each trait [Ww Yy Zz x Ww Yy Zz]. (a) What is the frequency of offspring resulting from the cross who are dominant homozygous--that is, whose genotype is [WW YY ZZ]?(b) What is the frequency of offspring whose phenotype is dominant for all three traits?
