Two rough black guinea pigs when bred together have two offspring. One of them is rough white and the other is smooth black. What are the genotypes of these parents?

Parent 1 __________ Parent 2 ___________

Answers

Answer:

Parent 1 = RrBb

Parent 2 = RrBb

Explanation:

This question involves two genes in guinea pigs. The allele for rough coat (R) is dominant to smooth coat (r), and the allele for black coat (B) is dominant to white coat (b).

According to this question, two rough black guinea pigs when bred together produced two offsprings. One of the offsprings is rough white (R_bb) and the other is smooth black (rrB_). This means that, to produce such offsprings, the parents must be both heterozygous for both genes (RrBb). Please find the punnet square for this cross attached

How would transcription of the E. coli trp operon be affected by changing the two Trp codons in the leader peptide gene to His codons?

Answers

Answer:

The attenuation system would respond more to histidine (His) than to tryptophan (Trp) levels

Explanation:

In genetics, the attenuation system refers to the process of control which is responsible for triggering premature termination of transcription in bacterial operons. In bacteria, the process of attenuation is characterized by the presence of an attenuator, which is a stop signal sequence found in the leader mRNA. The tryptophan (trp) operon, which is a cluster of genes responsible to encode the components required during the production of tryptophan, is controlled by the attenuation system. When there is a high tryptophan level, the ribosomes are able to translate an attenuator sequence, thereby resulting in termination of transcription. The attenuation system also controls the synthesis of other amino acids including histidine (His), phenylalanine (Phe) and threonine (Thr).
