I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.
We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.
It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
A Germ cell aka sex cell mutation can cause down syndrome when theres an extra chromosome d is a mutation caused by inserting or deletion of a nucliotide
1. is c
2. is d
The answer is 4. Hope this helps
Answer:
D) mRNA
Explanation:
In mRNA, genetic information is written from four letters, which correspond to the nitrogenous bases. This is called ogenated codon; A, C, G and U, forming long sequences of triplets. In mRNA, each of these consecutive, non-overlapping triplets is called the codon, which undergoes transient binding to the complementary aminoacyl-tRNA within the ribosome insertion sites during the translation process to establish initiation, elongation, and completion of polypeptide formation, plus a punctuation symbol.
