Hello, 3Coli here!

Here is your answer:

In  <u>external</u> fertilization, the female fish releases eggs in the water or on a surface. The male fish spreads sperm over the eggs to fertilize them.

In <u> internal</u><u> </u> fertilization, the eggs are fertilized inside the female's body. The young develop there until the female gives birth.

Hopefully, this helps! :D

"Draw a pedigree for hitchhiker’s thumb. Your pedigree should cover at least two generations and include both dominant and reces
igor_vitrenko [27]

Answer and Explanation:

First, you need to know how to interpret a pedigree representation.

  • Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

  • Trait/Phenotype

→ Healthy/normal/not affected  individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

  • Generations

→ Each file is represented with a roman number, indicating the Generation.

 

Now, what we need to do is to draw a pedigree for a hitchhiker’s thumb. We know that this is an autosomal dominant trait, which we will represent with an H. No hitchhiker's thumb is the recessive trait, and it will be represented with an h.

Our pedigree should cover at least two generations and include both dominant and recessive forms of the trait.    

  1. We can cross two heterozygous individuals, Hh, who are the first generation in our pedigree.
  2. This cross will result in a woman and a man with No hitchhiker's thumb, another man with a hitchhiker's thumb, HH, and another woman with a hitchhiker's thumb, Hh. These individuals will represent the second generation in the pedigree.
  3. Finally, we can cross the man with No hitchhiker's thumb, hh, with a woman who does not have a hitchhiker's thumb either, hh. And the woman with a hitchhiker's thumb, Hh, with a man with a hitchhiker's thumb, HH. The result of these crosses will be the third generation.

The representation would be like following,

I → <u>First-generation:</u> First cross

  • Man Hh (1)  
  • Woman Hh (2)

II → <u>Second-Generation:</u> F1 and second crosses

  • Man hh (3)  x    Woman hh (4)
  • Woman hh (5)
  • Man HH (6)
  • Woman Hh  (7) x   Man HH (8)

III → <u>Third-Generation:</u>

  • A boy (9) and a girl (10) hh
  • A girl (11) HH

You will find this pedigree in the attached files. In this example, we included three generations. The first one belongs to the grandparents, the second one to parents, aunts/uncles, and the third one to grandchildren.  

If you draw another pedigree, remember to include

  • the figures representing males and females,
  • color and H/h representing the phenotype,
  • Roman numbers representing the generations, and optional, numbers naming each member.

Since urological or gynecological exams rarely result in any sexual arousal and unwanted sexual advances produce only revulsion,
nignag [31]

Answer:

mind

Explanation:

  • An area present in the body that is highly sensitive and thus the stimulation of which may result in sexual arousal is termed as an erogenous zone.
  • There are different erogenous zones present in the body an all these zones vary in their sensitivity and these zones mainly provide a sense of pleasure upon stimulation.
  • However, the ultimate erogenous zone is the mind and one can say that it is a hidden erogenous zone as it is not exposed to tactile sensations like the other areas.
  • This is the reason why during urological or gynecological exams or unwanted sexual advances a person doesn't get sexually aroused even though the same areas are being touched.
