Who agrees that aliens have been in a symbiosis with the humans since the beginning? Some proof=

So many people claim seeing aliens, that you can't say they all are crazy/ mental disorders.

Governements are clearing it up so they can focus on their own power.

Every type of animal except for humans have breeds (possible genetic modification by aliens?)

Our intelligence.

Cave paintings with UFO's in them

Atlantis (possibly people once had alien technology)

Concepts of reincarnation (indigo aura people including myself know about incarnation without even hearing about it)

It's naive to think we are alone.



I only want serious people to answer this, if you are unnecessarily sarcastic or mean, I WILL report you. And give you "thumbs down".

10. A couple has a silver-eyed child. Both parents have purple eyes.

(a) Based on the information provided above, is the trait “silver eyes” dominant or recessive?

Answer: _______________________ (1)



Why/How do we know “silver eyes” are a dominant or recessive trait? (include an explanation of the parents genotype and how/why we know this!) (2)









(b) Using a punnett square, show how a mating of two purple-eyed people could produce a silver-eyed child. Remember to use the letter “E” as your allele. (1)

Describe the following genotypes using the words dominant/recessive, and homozygous/heterozygous.

When describing dominant inheritance, there are two options:

 _______________________ (Aa) and _______________________________ (AA). 

In recessive inheritance, there is only one option: _______________________ (aa).            
 

 

2. An individual with genotype Aa would create what kinds of gametes?

               

 

 

 

3. An individual with genotype AaBb would create what kinds of gametes?
