What is meant by emasculation? When and why does a plant breeder employ this technique?

The ABCDE Model of flower development dictates the combination of transcription factors require to initiate each whorl of a flower. Based on the diagram below, what would happen if: Carpels and ovules Sepal Petal Stamen 2 4 Whorl A Genes E 25-40 The ABCDE model of floral organ determination in Arabidopsis In addition to the A-, B-, and C-function genes of the ABC model, this model includes two additional gene classes, D and E. In the ABCDE model, class A + E genes specify sepals; class A + B + E, petals; class B +C +E, stamens; class C + E, carpels; and class C+ D + E, ovules. 1. Gene D was non-functional: 2. Gene E was non-functional: 3. Only Gene A was functional: 4. Gene B and E were non-functional: 5. Only Gene A and Gene E were functional: Hint: If Gene A was non-functional the flower would have no sepals or petals, it would be composed of only stamens and carpels.

You are a developmental geneticist studying flowering time variation in Arabidopsis. You perform a mutagenesis screen to identify mutants in the photoperiod pathway. Given what you know about photoperiodism in Arabidopsis, what phenotype are you looking for and under what photoperiodic conditions would you perform the experiment? delayed flowering in long days delayed flowering in short days same flowering in short days early flowering in short days same flowering in long days early flowering in long days
