Question
In monohybrid cross, the proportion of $3: 1$ explains(a) Dominance(b) Segregation(c) Both (a) and (b)(d) Unit factor
Step 1
This law states that in a two-generation, the dominant and recessive characters remain together for a long time but do not mix with each other. They segregate at the time of gamete formation. Show more…

Assuming alleles have a clear dominance relationship, a dihybrid cross leads to a phenotypic ratio in offspring that is close to _____ a. 1: 2: 1 b. 3: 1 c. 1: 1: 1: 1 d. 9: 3: 3: 1
Assuming complete dominance, crosses between two dihybrid $\mathrm{F}_{1}$ pea plants, which are offspring from a cross $A A B B \times a a b b,$ result in $F_{2}$ phenotype ratios of ___. a. 1: 2: 1 b. 3: 1 c. 1: 1: 1: 1 d. 9: 3: 3: 1
