In a plant species, a segregating line (RR- Red, Rr- Pink and rr- white) that contains both homozygotes and heterozygotes at a locus can be made homozygous by repeated selfing for several generations. What is the proportional red flower in third generations of selfing, if the level of heterozygosity in generation '0' is denoted as 1?

A 20-1 stirred fermenter containing a Bacillus thuringiensis culture at 30°C is used for production of microbial insecticide, ka is determined using the dynamic method. Air flow is shut off for a few minutes and the dissolved-oxygen level drops; the air supply is then re-connected. When steady state is established, the dissolved-oxygen tension is 78% air saturation. The following results are obtained. Estimate ka.
