Question

Item 2 The following figure shows the results of Mendel's test-cross analysis of independent assortment. In this experiment, he first crossed pure-breeding round, yellow plants to pure-breeding wrinkled, green plants. The round yellow F1 are crossed to pure-breeding wrinkled, green plants. RAGG Cross-fertilization Heterozygous Pure RrGg rr99 Cross-fertilization Frequency among Mendels 207 plants: rg Expected observed round 0.25 55 (0.266) yellow round 0.25 51 (0.246 rG rrGg wrinkled 0.25 49 (0.237) yellow wrinkled 0.25 52 (0.25 green .00 207 (1.000

Explanation / Answer

In this experiment shown, for independent assortment using a test cross, 4 Independent coordinates can be formed, or we can say that four independent characteristics can be observed.

In such case, n=4

Degree of freedom = n-1

Here, n= 4

so degree of freedom will be, =4-1 =3
