<h2>Answer is option " 2 & 4"</h2>

Explanation:

  • Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:  
  • m+g/mg : Parental  
  • mg+/mg : Parental  
  • m+g+/mg : Recombinant  
  • mg/mg : Recombinant  
  • m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
  • Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"

SVETLANKA909090 [29]

Answer:

The amount of light they receive.

Can you describe how a researcher might use naturalistic observation, case studies, and survey research to investigate gender di
Sati [7]

Answer:

The specification of the circumstance is characterized underneath in the interpretation category.

Explanation:

  • To continue investigating differences between men and women throughout the aggressive behavior of employees, a research scientist can use observation methods, research papers, or observational studies.
  • The naturalistic observation was being used without people's awareness to classify the actions of persons throughout the natural world. In this, the researcher examines individuals for some violent actions and often examines gender disparities throughout this workplace climate with aggressive behavior.
  • Throughout the case research, the researcher does a throughout-depth study on gender disparities mostly in current workplace violent behavior. Here also, not only would the researcher observe the behavior, and address questions about the gender gaps between the departments.
  • The investigator focuses on collecting information about the number, spread, and interrelationships of gender disparities throughout the large population through survey studies.

Hypothesis:

  • <u>Research hypothesis (H1): </u>There seems to be a correlation among both gender differences but instead aggressive performance in the workplace.
  • <u>Null hypothesis (H0):</u> There seems to be no correlation regarding disparities in gender as well as violent work performance.

Research approach:

Qualitative descriptive research design could be employed throughout the descriptive research. In all of this, more attention is put on gathering knowledge about prevalence as well as the interconnection of gender disparities with occupational violent behavior. In this, this same data will be gathered by face-to-face interviews, questionnaires on genetic factors, and occupational hostile behavior.
