Answer:
no population at maximum density............. The carrying capacity is the maximum number of individuals that the environment can sustain.
Answer:
B. there were more double crossovers in the progeny than would be expected based on probability
Explanation:
Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:
Coefficient of coincidence (COC) = ADRF / EDRF
where ADRF = Actual Double Recombinant Frequency
and EDRF = Expected Double Recombinant Frequency
In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
