Answer - A. Mating Must occur randomly
Reasoning - Since mating must occur randomly are helps with the balance or equilibrium in genetic without any changes within that population since we do not want genetic drift, mutation and especially do not want any foreign or different species mating with the species we are targeting. So A is your best answer.
I’d say the flagellum. This is a tail-like organisme that helps some cells to move.
Answer: Its possible genotypes are PPSS, PPSs, PpSS, and PpSs.
Explanation: If P represents the allele for purple kernel and S represents the allele for smooth seed shape; if P and S are dominant alleles, PP and Pp will manifest outwardly as purple kernel because P is dominant and will be able to express itself whether in a homozygous or heterozygous state. Similarly, SS and Ss will manifest outwardly as smooth seed shape because S is dominant and will be able to express itself whether in a homozygous or heterozygous state.
Therefore, PPSS, PPSs, PpSS, and PpSs will appear outwardly as purple kernel and smooth seed shaped corn plant.
