Question
A Mendelian experiment consisted of breeding pea plants bearing violet flowers with pea plants bearing white flowers. What will be the result in F1 progeny?
Solution
•We know that violet colour of the flowers is a dominant trait and the white colour of the flowers is recessive.
•When pea plant bearing white flowers is bred with a pea plant bearing white flowers the resulted F1 progeny would consist of all violet flowers.
•The result can be explained by looking at the following figure:
•The dominant violet flower is represented by VV where as the recessive white flower his represented by vv.
•On cross breeding, the two plants we get plants having the characters Vv, Vv, Vv and Vv. Since V (i.e. violet colour) is dominant all flowers are violet.

Excited by his observation of different types of ear lobes present in his family, Rahul conducted a survey of the type of ear lobes found {Figure (e) and (f)} in his classmates. He found two types of ear lobes in his classmates as per the frequency given below:
| Sex | Free | Attached |
| Male | 36 | 14 |
| Female | 31 | 19 |
On the basis of the above data answer the following questions.
- Which of the two characteristics - ‘free ear lobe’ or ‘attached ear lobe’ appears to be dominant in this case? Why?
- Is the inheritance of the free ear lobe linked with the sex of the individual? Give a reason for your answer.
- What type of ear lobe is present in father, mother, Rahul and his sister Nisha? Write the genetic constitution of each of these family members which explains the inheritance of this character in this family.
(Gene for the Free ear lobe is represented by F and the gene for the attached ear lobe is represented by f for writing the genetic constitution).
