Biology
1 answer:
meriva3 years ago
6 0

Answer:

A. If neither parent expresses the trait, but the offspring does, both parents must be heterozygous for the trait.

Explanation:

If neither parents express the trait is because they are heterozygous and the dominant allele is being expressed over the recessive trait. When parents cross they have 25% of having an offspring that expresses the recessive trait, this means the offspring is a recessive homozygous. In the attached example 25% or 1/4 will have a short stem.

Describe three examples of materials that have resulted from a lack of decomposer activity
erastova [34]

The decomposers are of two kinds, aerobic decomposers and anaerobic decomposers. The aerobic decomposers need the oxygen from the air to break down the dead and decaying matter into simple salts, sugars and hydrocarbon gases. The anaerobic decomposers do not require oxygen for the break down of dead and decaying matter. They break down the matter into various forms of hydrocarbons, sulphides and nitrogenous compounds.

When a dead and decaying matter gets buried deep within the Earth where there is an absence of the decomposers, it takes the form of crude oil, coal, peat, asphalt, and natural gas. The matter gets compressed by the weight of the rocks above and changes its form.

Why are frameshift mutations likely to be more detrimental than point mutations, in which a single pyrimidine or purine has been
lisabon 2012 [21]

Answer:Frameshift mutations are likely to change more than one amino acid, infact a completely irrelevant protein with altered amino acid sequence is produced.

Explanation:

Frameshift mutation is due to addition or deletion of bases. From that point onwards the reading frame shifts, different set of codons read. Frameshift mutations are likely to change more than one amino acid, infact a completely irrelevant protein with altered amino acid sequence is produced.

Frame shift mutation can lead to thalassemia due to premature chain termination and run-on-polypeptude that are non-functional.
