A red Blood b ceII will only shrink when placed in salt water.
Answer:
The correct answer would be - the ratio of phenotypes in an organism cross will tell if the genes are linked or not.
Explanation:
In this question, we perform a test cross with a fruit fly that is heterozygous If we perform a test cross between two parents with identical heterozygous genomes AaBb.
If there is no recombination found in the offspring of this cross it means there are no linkage of genes present. And if there are new or recombinant phenotypes present it means that there are genes linked together.
Step 1: Figure out genotypes of parents
Jessica's mom: I^A I^B
Jessica's dad: ii
Step 2: Punnett Square:
( i ) ( i )
(I^A) I^Ai I^Ai
(I^B) I^Bi I^Bi
Step 3: List possible phenotypes
Jessica could be either blood type A (I^Ai) or blood type B (I^Bi)

Answer: An external factor caused damage to the nerve cells. However, the injection of new cells into the injured area prompted a beneficial change. The injured cells received proteins that decreased inflammation and pain in the mice.
