How a change in glycoproteins affects a cell’s ability to maintain homeostasis

Explanation:

Most of the cell surface receptors and glycoproteins. These glycoproteins have active sites that recognize specific signals, like hormones, that initiate secondary signaling pathways inside of the cell, in response to the external signal. This is how cells respond to environmental stimuli.

If a change in glycoproteins makes them unable to bind signaling molecules (like hormones) or makes them permanently bind these molecules, there will definitely be a defect in how the cell responds to external stimuli. The cell will be, for example, be unable to respond to insulin in case of elevated blood sugar levels as is the case with diabetics.

In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l

melisa1 [442]

The answers would be:

Genotype Phenotype

Tt Tall stemmed

tt Short stemmed

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1

You can read on to see how this was done:

Tall stems (T) are dominant to short stems (t).

First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.

For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.

Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.

Now we can make our Punnett Square.

tt x Tt

t t

T | Tt | Tt

t | tt | tt

Let's list down the genotypes and phenotypic results.

Genotype no. Phenotype

Tt 2 Tall stemmed

tt 2 Short stemmed

So from that we can answer the other questions:

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1
