Answer:
Well, DNA's arranged in chromosomes, as you know, so what happens is, as a chromosome replicates, or makes a copy of itself, it's arranged as two chromosomes next to each other, called chromatids.

Answer;
-Medulla
Your life would be most immediately threatened if you suffered destruction of the Medulla.
Explanation;
The medulla oblongata is a portion of the hindbrain that controls autonomic functions such as breathing, digestion, heart and blood vessel function, swallowing, and sneezing. It is located in the brainstem, anterior and partially inferior to the cerebellum.
-The medulla is easily the most important part of the brain. It's functions are involuntary, or done without thought. We would not be able to live without the medulla because of the myriad of crucial tasks it performs including regulating blood pressure and breathing.
Matter is anything that takes up space. Your mass determines how big, or small you are. Or, how big or small something is. Matter is in everything. Even air has matter. Humans are made of matter. Matter makes up atoms, carbon, cells, and everything else you can think of. (Except ideas)
Answer:
The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.
Explanation:
<u>Available data</u>:
- The gene for petal color in a flower has incomplete dominance
- Two A1 alleles (A1A1) express black color
- Two A2 alleles (A2A2) express white color
- One of each allele (A1A2) express mottled color
In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:
Parental) A1A1 x A1A1
Gametes) A1 A1 A1 A1
Punnet Square) A1 A1
A1 A1A1 A1A1
A1 A1A1 A1A1
F1 Phenotypes: 100% black flowers
F1 Genotype: 100% A1A1
There are 0% of probabilities of getting a mottled offspring.
