The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by a recessive mutant gene that independently
rusak2 [61]

Answer:

It is expected to obtain 576 individuals with normal wings and body with normal hair, 192 with normal wings and hairy body, 192 with vestigial wings and body with normal hair, and 64 with vestigial wings and hairy body.

Explanation:

Since only the wild-type of the offspring cross each other and since the parents have antagonistic phenotypic characters for each gene, all the progeny produced in the F1 is heterozygous with VgvgHh genotype, where

Vg: Normal wings.

eg: Vestigial wings.

H: Body with normal hair.

h: Hairy body.

Once F1 reproduces with each other, the Mendelian proportions 9/16, 3/16, 3/16, 1/16 expected in the F2 generation are produced.

Since in total there were 1024 individuals in the offspring, this amount is multiplied by the expected proportions, giving rise to the mentioned result.

Future consequences if nothing is done to human trafficking
Kipish [7]

Answer:

Human trafficking affects victims in all aspects of their lives. Everything from physical and s**ual abuse to torture and the use of drugs to economic exploitation and living and working conditions that are abusive can be a part of the human trafficking process. Unlike most other forms of violent crime, human trafficking frequently results in long-term and repeated trauma. Research and documentation described the physical and psychological effects of abuse on men, women, and children in a variety of exploitative situations. People who have been trafficked are at a high risk of contracting HIV for a variety of reasons. In addition to PTSD and other mental health issues, victims of human trafficking may also suffer from symptoms such as panic attacks, insomnia, irritability, and irritability. According to studies, trauma worsens during the trafficking process and can last long after the exploitation ends. Because of their age, immaturity, and lack of experience, child victims are especially vulnerable to trafficking, to abusive practices that may, for example, stunt their further physical development, and to continued victimization as a result of attachment, developmental, and social difficulties. Third parties may find it difficult to comprehend the behavior of trafficking victims, and victims may find it difficult to comprehend what has happened to them, let alone discuss or explain it to others. Victims may appear uncooperative, irritable, hostile, aggressive, or ungrateful to those around them, including supporters. The stigma attached to them as victims has been shown to have a significant and long-term impact on their lives, including trauma and the possibility of physical rejection by family and community. Human trafficking has long-term consequences for individuals that are complex and dependent on a variety of factors, with no guarantee of recovery. Re-victimization is a common side effect of the experience.
