Zoology - Principles of Inheritance and Variation Question with Solution | TestHub
In a typical Mendelian dihybrid cross, one parent is homozygous for both dominant traits and another parent is homozygous for both recessive traits. In thegeneration, both parental combinations and recombinants type appear. The phenotypic ratio of parental combinations to recombinants is
Options:
Answer:
Solution:
When two pure pea plants one with yellow round seeds and one with green wrinkled seeds are crossed, all plants in thegeneration have yellow round seeds. On selfing they will produced organisms with yellow round seeds, yellow wrinkled seeds, green round seeds and green wrinkled seeds in the ratio. Out of these yellow round seeds and green wrinkled seeds are parental combinations while yellow wrinkled seeds and green round seeds are recombinations. Thus the phenotypic ratio of parental combinations to recombinations is
