Mandel crossed a homozygus pea plant having yellow round seed with another pea plant bearing green wrinkled seed. He found that in some of the f2 population new combination of parental charecters were observed.
Question
Mandel crossed a homozygus pea plant having yellow round seed with another pea plant bearing green wrinkled seed. He found that in some of the f2 population new combination of parental charecters were observed.
Solution
The question seems to be incomplete. However, I can explain the concept related to the information given.
Gregor Mendel, the father of genetics, performed experiments on pea plants (Pisum sativum) to understand the inheritance of traits. He crossed a homozygous pea plant with yellow round seeds (YYRR) with another pea plant with green wrinkled seeds (yyrr).
In the F1 generation, all plants had yellow round seeds (YyRr) because yellow and round are dominant traits.
When Mendel allowed the F1 generation to self-pollinate, he observed the F2 generation. In the F2 generation, he found that the traits segregated, producing some offspring with the new combination of parental characters.
The possible combinations in the F2 generation are:
- Yellow Round (YYRR, YYRr, YyRR, YyRr)
- Yellow Wrinkled (YYrr, Yyrr)
- Green Round (yyRR, yyRr)
- Green Wrinkled (yyrr)
This observation led to the formulation of Mendel's law of independent assortment, which states that allele pairs separate independently during the formation of gametes. This means that traits are transmitted to offspring independently of one another.

In 1866, Mendel published three main conclusions to his findings. Which of the following ideas was not proposed by Mendel?Characteristics are determined by hereditary unitsHereditary units are organised in chromosomesHereditary units can be dominant or recessive Hereditary units are passed on unchanged by both parents3The height of Mendel’s pea plants is controlled by a single gene with two alleles: a dominant tall allele (T) and a recessive short allele (t). In a series of F1 crosses involving one homozygous tall plant (TT) and one short plant (tt), 400 F2 offspring were produced. Approximately how many of these offspring would you expect to be short?200Zero4001004In a series of crosses involving pea plants heterozygous for the height gene, 800 offspring are produced.
