Suppose that a farmer wishes to start a you‑pick berry farm, where customers pick their own fruit from the berry bushes. In this

variety of berry, the tall, thornless, and terminal flower phenotypes are produced by the s, t, and a alleles respectively. These phenotypes are recessive to the short, thorned, and axial flower phenotypes, which are produced by the S, T, and A alleles. The farmer has two berry plants. When selfed, the first plant produces tall, thorned plants with a mixture of axial and terminal flowers. The other plant produces a mixture of tall and short plants, which are all thornless and have terminal flowers. The farmer wishes to generate a pure‑breeding line of tall, thornless plants with terminal flowers, as such plants are most convenient for berry‑picking. What are the genotypes of the farmer's two original berry plants?

Answer:

The genotypes of the two original plants the farmer has are as follows:

Plant 1: ss,TT,Aa and Plant 2: Ss,tt,aa.

Explanation:

A genotype is literally the underlying makeup that will produce a result that is visible and measurable, that we know as phenotype. In this particular case, we have a farmer who wishes to establish his farm with a specific type of plant: one that is tall, thornless, and has terminal flowers because they are the best for berry-picking, and that is the business he wishes to establish.

In order to be able to obtain this type of plant, he needs to first count with a starting point, the parent plants from which he will be able to produce the line he wants to establish. But to do that he needs to first know the genetic makeup with which, when he crosses the plants, he will then obtain the phenotypical results he seeks.

The question itself tells us the types of alleles (which are, in simple terms, the holders of the genetic information), that produce the phenotypical characteristics of the plants the farmer has.  So we know that there is one type of bush that is tall, thornless and has terminal flowers, and its alleles are s, t and a. The other bush has short, thorned and axial characteristics, and therefore its alleles are: S, T and A.

When the question then gives us the information about the resulting plants when the originals are selfed, and their characteristics, we are able to tell the genetic makeup, or genotype, of the original two plants the farmer has because we can combine the alleles mentioned given the characteristics (phenotypes) and thus obtain the two parent plants.

Traits are passed from parents to offspring. These traits are determined by
musickatia [10]

Answer:

The traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.

Explanation:

During reproduction, there is a fusion of;

male gamete

female gamete

This leads to the formation of offspring. There is a transfer of traits from the parents to the offspring.

Hence, the traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.

Answer;

Low birth weight.

One of the most consistent and best documented effects of cigarette smoking during pregnancy is low birth weight.

Explanation;

Smoking during pregnancy has various effects on the fetus, causing a baby to be born early or to have low birth weight which makes it more likely for the baby to get sick and stay in the hospital longer.

Additionally; smoking during and after pregnancy is a risk factor of Sudden Infant Death Syndrome.

Which amino acids are the primary nitrogen donors for biosynthetic reactions in the cell?
prohojiy [21]
Glutamine and glutamate are the primary nitrogen donors for biosynthetic reactions in the cell.  Glutamine is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. Glutamate is generally acknowledged to be the most important transmitter for normal brain function. Nearly all excitatory neurons in the central nervous system<span> are glutamatergic, and it is estimated that over half of all brain synapses release this agent. Glutamate plays an especially important role in clinical neurology because elevated concentrations of extracellular glutamate, released as a result of neural injury, are toxic to neurons</span>
