Which genotype below represents a dihybrid individual? a: bbee b: bbee c: bbee d: bbee

Option C, BbEe

Explanation:

In a dihybrid cross, following is essential -  

a)Alleles for two different traits must be involved

b)The genotype of crossing parents must be heterozygous for both the traits.  

For example –  

Let us say the two different traits are – seed color and shape.  

“G” represents allele for dominant green color pea and “g” represents allele for recessive  yellow color peas.  

Also “S” represents allele for dominant smooth pea and “s” represents allele for recessive wrinkled pea

Now a dihybrid parent will have following genotype –  

GgSs

Hence, option C is correct

the answer is d p: cell, q: organ, r: organ system, s: tissue
