Answer: C, offsprings produced are infertile
Explanation: I just got it right on my test
Rr and rr in the ratio of 1:1
Explanation:
If allele for smooth seed is Dominant over the allele for wrinkled seeds, and they are crossed 50 per-cent of the progeny will be heterozygous dominant and 50 per-cent will be homozygous recessive.
Rr X rr
Rr Rr rr rr F1 generation.
r r
R rR rr
r Rr rr
From Punnet square it will be 50 per-cent chance each of rr and Rr.
Answer is B. The number of the question that should be considered next. Let's say your organism has a dorsal fin, then you would go to 5. Then you choose a or b depending on the location of the tail. Let's choose 5a for now. Across from it says 6, so you go to 6
Answer/Explanation:
EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.
A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.
