A genotypic ratio of 1:2:1 and a phenotypic ratio of 3:1 results from a(n) _______ cross.
A. test
B. monohybrid
C. dihybrid
D. allelic
Homework Answers
Ans) 1) B. Monohybrid
Explaination:
- A monohybrid cross is a mating between two individuals with different alleles at one genetic locus of interest. The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive).

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...
