Answer:

The options are

A. Recessive genes

B. Dominant genes

C. Different environmental experiences

D. Shared environmental experiences

The answer is D. Shared environmental experiences

Explanation:

The most likely cause of a disorder if both monozygotic and dizygotic twins show a high concordance rate is shared environmental experiences.

This is because twins usually have a very high degree of concordance rate i.e they have similar genetic traits and characteristics as a result of factors such as Recessive and Dominant genes. The disorder or abnormality which would support this is them having shared environmental experiences which will make them have it in common unlike different environmental experiences which will aid variation.

A series of choices between two characteristics that is used to identify organisms is called a?

Stella [2.4K]

The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.

In Drosophila, straight wings are dominant to curved wings (c), smooth eyes are dominant to sparkling eyes (spa), and tan body i

77julia77 [94]

Answer:

$\frac{1}{8}$

Explanation:

Straight wings are dominant over curved wings

Let Straight wings : H

curved wings : t

smooth eyes are dominant to sparkling eyes

let smooth eyes = H

spark ling eyes = t

tan body is dominant to ebony body color.

Again; Let tan body color be H

Let ebony color be t

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be $\frac{8}{64}$

= $\frac{1}{8}$

If a solution process is exothermic, how does the energy required for dissolving the solute compare with the energy released?

Misha Larkins [42]

If a solution process is exothermic, the energy required for dissolving the solute compare with the energy released is that, the energy requiredis less than the energy released. When we sayexothermic, heat is evolved. On the other hand,when heat is absorbed, this is called endothermic.
