Hey guys! Can you help with two questions? 1. How did I get a trait that neither of my parents had? 2. What is the probability t
astraxan [27]
1.The trait is recessive. This means both your parents were carries, but did not show the trait. For example, B represents the allele, you're parents would have to both be Bb. This means that they are carriers, and you could have inherited either BB/Bb/bb - you actually inherited bb, which means because its a recessive trait you will show the trait. 

2. For your children, it depends on who you have them with. Because you're bb, you will definitely pass on the b allele, so any child you have would be a carrier and could potentially have the trait. If you have a child with someone BB, all your offspring will be Bb (carriers- as the kid gets one allele form each parent). If you have a child with someone who is bb, all your kids would definitely have the trait. However, if you have a child with someone who as Bb, then the four outcomes are Bb Bb bb bb, so there would be a 50% chance of your kid having the trait.



Hope this helps!! :)

#13.) 3, Devonian.

What must happen for a mutation to affect evolution?
lara31 [8.8K]

I found this in a website, “A mutation is a change in DNA, the hereditary material of life. ... So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.”

Branliest please?
