Answer:

25%

Explanation:

The child only comes out as homozygous dominant (YY) for the trait in 1/4 boxes in the Punnett Square. This translates to the child having a 25% chance of being homozygous dominant for the trait.

Answer:

Homozygous is when the two letters are the same and dominance is represented by capital letters. There is one square that has two capital letter so 1/4 is equal to 25%. Hope this helps

Suppose that a farmer wishes to start a you‑pick berry farm, where customers pick their own fruit from the berry bushes. In this
Aleks04 [339]

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.

How does a diversity of organisms increase the chances that some will survive a major change in environment ?
Slav-nsk [51]
<h2>Answer:</h2>

This can be explained with an example.

Let’s lake an example of two species 1 and 2.

Species 1 has a wide genetic diversity due to which organism are also diverse in phenotype. Their phenotype are:  

Black, dark brown, brown, dark red, red, light red, pink, skin color.

From left to right organism are becoming less adapted to high temperature relatively.

For species 2:  This species has less genetic diversity and its phenotypic diversity is as follow:

Black, red, Skin color.

From left to right organism are becoming less adapted to high temperature relatively.

Now if there is the sudden high temperature in the environment; 4 Types of phenotype will survive are black, dark brown, brown, dark red.

While there will only two types of organism in specie 2 which will survive are black, red.

So that’s how the diversity of organisms increase the chances that some will survive a major change in environment.
