mafiozo [28]

The idea it can describe is that it is the transfer of information from one neuron to another.

<h3>Transfer of information </h3>

The nervous system is part of the body systems that helps in the transfer of information from nerve to nerve and from nerve to muscle tissues.

The presynaptic nerve is the nerve that sends the information that is to be conveyed in form of action potential impulses.

The impulses led to the release of neurotransmitters from the terminal of the presynaptic nerve to the synapse. This binds to the receptor if the postsynaptic cell which receives the message.

When two alleles are dominant and both are expressed in an individual, what kind of non-Mendelian inheritance is that?

NeTakaya

Answer:

Codominance

Explanation:

This case happens when both alleles are dominant then they will be equally expressed in phenotype

I can give you an example to understand this topic such as blood type: in the type AB both A and B are codominant = 2 dominant alleles are expressed together

In maize (corn) plants, a dominant allele I inhibits kernel color, while the recessive allele i permits color when homozygous. A

EleoNora [17]

Answer:

Phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio= 1:2:1:2:4:2:1:2:1

Explanation:

According to the given information, the dominant allele "I" is epistatic to P and p alleles and presence of "I" inhibits the expression of both "P" and "p" alleles.

A cross between two heterozygous plants for both locus would give the F2 progeny in 12 colorless: 3 purple: 1 red ratio.

Here, the F2 genotype with "I-G" and "I-gg" would produce colorless kernels while the ones with "ii-G-" would exhibit purple colored kernels. The F2 genotype "iigg" would beak red kernels.

Hence, the phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio would be same as for the mendelian dihybrid cross= 1 IIPP: 2 IIPp :1 IIpp: 2 IiPP :4 IiPp: 2 Iipp: 1 iiPP :2 iiPp: 1 iipp
