A total of 192 offspring can be produced in the dihybrid cross.
For a dihybrid cross, the resulting plant ratios in the F2 generation are 9:3:3:1.
Accordingly, the fraction of yellow round offspring is 9/16, green round offspring is 3/16, yellow wrinkled offspring is 3/16, and green wrinkled offspring is 1/16.
The calculation for green and round offspring is as follows:
Green round seed = 3/16
= 3/16 × 192
= 576/16
= 36
Hence, from 192 peas, 36 will be green and round.
The probability is 75%, as this represents 3/4 of the offspring being dominant.
Answer:
Haploid organisms contain a single allele per locus.
Explanation:
Haploid species will always have only one allele present for any given locus. These organisms possess one full set of chromosomes in their somatic cells. Although most species are typically diploid, there are exceptions (for instance, male bees, ants, and wasps develop from an unfertilized egg). Hence, in haploid organisms, the frequencies of alleles and genotypes are identical. It is also noteworthy that the remaining three alleles will be allocated among the other haploid individuals in the population.
Earth system processes occur across a range of spatial dimensions from mere millimeters to many kilometers, while their temporal scales span from milliseconds to billions of years.

Initially, the scientist needs to determine the specific point in the Cretaceous period he wishes to investigate. This could involve studying the development of microorganisms from that era, the life cycle of a certain dinosaur species, or the evolution of dinosaurs, as well as the flora associated with that epoch, among other topics. This is referred to as the Observation phase of the scientific method.
Next, he will enter the phase known as "Hypothesis formulation" where he will pose inquiries relevant to his chosen study area. Questions might include, "How many flower types existed during that time?" and "Which of these flowers still exist today?" and so on.
Following this, he will proceed to the "Experimentation phase," where he will set up an experiment along with determining factors and variables crucial for answering the proposed hypotheses.
After conducting the experiment, data will be collected for analysis to generate results that address the previously established hypotheses. This step is termed "Data analysis."
Finally, he will reach the last step of the scientific method called "Conclusions," during which he will share the findings derived from the experiments.
