How does inbreeding alter genotype and allele frequencies?

Biology
1 answer:
erik [133]4 years ago
6 0

Explanation:

The inbreeding process, are blood crossings between relatives who have a common ancestor. Inbreeding leads to an increase in the frequency of homozygous genotypes and a decrease in the frequency of heterozygotes. We may also note that although changes in genotypic frequencies occur, no changes in allelic frequencies are observed over successive generations of self-fertilization. The main consequence of 2 individuals sharing one or more common ancestors is that they may carry replicas (identical copies) of one or more genes present in these ancestors. And if these individuals mate, they can pass on such replicas to their offspring, generating self-sibling offspring, that is, with two identical copies of the same gene that was present in these common ancestors.

explain how repressible and inducible operons differ and how those differences reflect differences in the pathways they control
Sonja [21]

Answer

Operons are cluster of coordinated genes, including structural genes, an operator gene, and a regulatory gene.

Explanation:

In the The repressible operons, The transcription is usually on and repressor is in inactive form, So the specific genes are transcribed. While a regulatory molecule act as corepressor and binds to repressor protein to activate it. The repressor protein cause the inactivation of repressible operon (as the name indicate). E.g., Tryptophan Repress the trp operon.

A high level of product act as regulatory molecule (Corepressor) and turn off the operon, So anabolic pathways or synthesis of essential components are controlled by repressible operon.

In the Inducible operons, the transcription is usually off and repressor is in active form. So there is no transcription of genes. Specific Metabolite cause the activation of operon  e.g lactose cause the induction of lac operon.

As a metabolite induces the operon, So they control the Metabolic pathways or breakdown of a neutrient.

A victim with a foreign-body airway obstruction becomes unresponsive. what is your first course of action
Mrrafil [7]
The answer to this question would be: start doing CPR.

If the victim becomes unresponsive, probably the foreign body completely obstructs the airway and the oxygen level is already too low. Without the victim help, taking out the foreign body will be hard.
In this case, CPR will be the best option since the pressure from chest might push the foreign body away and the CPR can help circulate the blood.
