Mouse Genetics (Two Traits) Assignment: Lab Report

Biology
1 answer:
zlopas [31]3 years ago
4 0

Answer:

Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur and eye color are reported every time a pair of mice breed.

Photopigment genes are located on the X chromosome. Color blindness occurs when an individual has missing or damaged alleles. A
Hunter-Best [27]

The probability that their son exhibits the 'color blind' trait is 0%. It is a type of inheritance linked to the X chromosome.

<h3>Inheritance linked to the X chromosome</h3>

In men, the patterns of inheritance linked to the X chromosome don't follow conventional mendelian inheritance because men have only one X chromosome.

Conversely, women have two X chromosomes, thereby the inheritance pattern resembles Mendelian inheritance.

It is important to highlight that color blindness is a recessive trait on the X chromosome.

In this case, the mother is a carrier, thereby the probability of passing this trait as a carrier to her son is 50%, whereas the father is normal, thereby the probability of passing this trait to his son is 0%.

g A mutation occurs upstream of gene A in the region encoding the ribosome binding site, making it bind more weakly to the ribos
Ivanshal [37]

Answer:

it is expected that the mutation results in a reduced initiation of translation and thereby decreasing the level of the protein A, while it does not change the level of mRNA A

Explanation:

Translation in bacteria starts with the formation of the initiation complex which is composed of the small ribosomal subunit, the messenger RNA (mRNA), initiation factors and the initiator transference RNA (tRNA) containing N-formyl-methionine. The small ribosomal subunit binds to a polypurine stretch of variable length in the mRNA called 'the Shine-Dalgarno sequence'. A mutation in this sequence reduces the affinity of the ribosome for the mRNA, thereby, in this case, decreasing the level of protein A. Since transcription occurs before translation, it is expected that this mutation does not change the level of expression of the mRNA A.
