Question

In Lathyrus odoratus, the cross between two purple flowered plants gave a pink flowered progeny. This is due to

a)

incomplete dominace

b)co-dominance

c)

segregation

d)complemetary gene interaction

Correct answer is option 'C'. Can you explain this answer?

Answer

In case of incomplete dominance the pair of allel express itself partially no one is dominant nd noone is recessive... both express itself simultaneously and give a new variety of pink colour of flowers

Answer

In incomplete dominance, both the alleles expresses itself partially. two alleles are responsible for the flower color of lathyrus, 1st allele codes for white and the second color for red. when progeny of the pure f1 generation is observed, it is seen that progeny gives pink flower. due to incomplete dominance.

Answer

C: Segregation- Definition of Segregation: Segregation is the separation or sorting out of alleles during the formation of gametes (reproductive cells) in the process of meiosis. Each parent contributes one allele for each trait to their offspring, and these alleles segregate during the formation of gametes. - Inheritance of Flower Color in Lathyrus odoratus: Lathyrus odoratus, commonly known as the sweet pea, exhibits a simple inheritance pattern for flower color. Purple flowered plants have a dominant allele (P) for purple flower color, while pink flowered plants have a recessive allele (p) for pink flower color.- Cross Between Two Purple Flowered Plants: When two purple flowered plants are crossed, each parent contributes one allele for flower color to their offspring. In this case, both parents contribute the dominant allele (P) for purple flower color.- Resulting Pink Flowered Progeny: The fact that the cross between two purple flowered plants gave a pink flowered progeny indicates that the offspring inherited two recessive alleles (pp) for pink flower color. - Explanation: This phenomenon is due to the segregation of alleles during the formation of gametes. Each parent carries the dominant allele (P) for purple flower color, but their offspring received two recessive alleles (pp) for pink flower color. This is because during meiosis, the alleles segregate and randomly combine to form gametes, resulting in the inheritance of two recessive alleles in the offspring.- Conclusion: Therefore, the cross between two purple flowered plants in Lathyrus odoratus giving pink flowered progeny is an example of segregation, as the alleles for flower color segregate and recombine to result in the observed phenotype.
