The most likely explanation for the irregular expression of hairlessness on the mother's skin is codominance

Codominance is a biological term to refer to the hereditary pattern that is characterized by:

  • In the heterozygous state, there is no recessive allele, but both behave as dominant. Codominance is characterized by the manifestation of both characteristics as dominant, without mixing.

According to the above, the irregular expression of the lack of hair in the mother is a manifestation of the codominance of the hair gene and the hairless gene that do not mix but are seen independently.

Explain how he interaction between mRNA codons and tRNA codons anticodons codes for a specific amino acid
Julli [10]
<span>The interactions between the mRNA codons and the tRNA anticodons  codes for a specific amino acid is by, it is the job of the tRNA to start working after the mRNA has able to have its own complementary copy. The mRNA will undergo to the nucleus and will move out, in order to go the rrna. The three nucleotides codes the specific amino acid of the trna. The trna and the mrna will be matched, it will now release the amino acid in the trna that wil form a peptide bond. When the mrna is able to be decoded to form an amino acid, it will now have the ability to break and make proteins in different structures.</span>

PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each
Grace [21]

Answer:

There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.

Explanation:

Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing - too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.

Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.
