Some inbred strains of the weedy plant Arabidopsis thaliana flower early in the growing season, but other strains flower at late
RoseWind [281]

Answer:

a. Let us consider that L is responsible for late and l is responsible for early. From the mentioned data, it can be concluded that allele L or late is dominant over early. By crossing plants 1 and 4 we get the expected ratio of 3: 1, which shows that it follows Mendel's law of dominant.  

b. The genotype of all the four plants are:  

1st plant = Ll

2nd plant = ll

3rd plant = LL

4th plant = Ll

c. If the plant 1 is self-fertilized then the expected progeny will be 3 (late): 1 (early).  

In case if the 2nd plant is self-fertilized, the expected progeny will be only early.  

In case if the 3rd plant is self-fertilized, the expected progeny will be only late.  

In case if the 4th plant is self-fertilized, the expected progeny will be 3 (late): 1 (early).

The organism could not arise only through the sexually and the asexual reproduction but it is also reproduced through the process of spontaneous generation.

The essential character is offspring is while mother supply is the only solid substrates. The reproduction also takes place by either the egg of the mother or the sperm of the father and began to grow when it is stimulated.
