Q.9 Alleles B and b are co-dominant. Two heterozygous individuals were crossed. What would be the expected ratio of phenotypes in the F1 generation? (2) A. 1:1 B. 3:1 C. 1:2:1 D. 1:1:1:1
Added by Emilio G.
Step 1
In co-dominance, both alleles in the heterozygous state are fully expressed. This means that neither allele is dominant or recessive, and both alleles contribute to the phenotype. For alleles B and b, both will be expressed in a heterozygous individual (Bb). Show more…

In a mating between two individuals that are heterozygous for a recessive lethal allele that is expressed in utero, what genotypic ratio (homozygous dominant:heterozygous:homozygous recessive) would you expect to observe in the offspring? a. 1: 2: 1 b. 3: 1: 1 c. 1: 2: 0 d. 0: 2: 1
Assuming no gene linkage, in a dihybrid cross of $A A B B \times$ aabb with $A a B b$ F 1 heterozygotes, what is the ratio of the $\mathrm{F}_{1}$ gametes $(A B, a B, A b, a b)$ that will give rise to the $\mathrm{F}_{2}$ offspring? a. 1: 1: 1: 1 b. 1: 3: 3: 1 c. 1: 2: 2: 1 d. 4: 3: 2: 1
