What ratio of plants in the offspring would you predict from a Yy x Yy cross?

Biology
1 answer:
ziro4ka [17]3 years ago
3 0

Answer:

The correct answer is -

The genotype of offspring - 1:2:1 (YY:Yy:yy)

The phenotype of offspring - 3:1 (dominant trait: recessive trait)

Explanation:

In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y

then the cross of Yy and Yy would be -

      Y      y

Y    YY    Yy

y     Yy    yy

Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.

The relationship between catabolism and anabolism is most similar to the relationship between which of the following pairs of te
MrMuchimi

Answer:

The pair of terms whose relationship is very similar to the relationship between catabolism and anabolism are exergonic and endergonic.

Explanation:

Anabolism and catabolism are processes that occur in matabolism, whose result is different.

  • <u><em>Anabolism </em></u><em>involves all the processes of manufacture or synthesis, in which chemicals are bound together to form new compounds. This process consumes energy, so it is called </em><em>endergonic</em><em>. </em>
  • <u><em>Catabolism</em></u><em>, unlike anabolism, is the process of degradation of complex molecules into simple molecules. One of the results of catabolism is the release of energy, which is equivalent to saying that it is an </em><em>exergonic</em><em> process. </em>

Relating catabolism to anabolism is similar to relating exergonics to endergonics.

  <em>  The other terms do not represent a similarity with the relationship between the processes of catabolism and anabolism.</em>

The bones in a bird are hollow, reducing its weight for flight. This is an example of which characteristic of life?
dimulka [17.4K]

The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.

<h3>Adapatation and environment</h3>

Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.

For example, the bones in a bird are hollow because this adaptive feature enables them to fly.

Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.

How can changes In one part of a food web affect another part?
Gala2k [10]
In a food web there is a hierarchy, if any one of the parts of a food web is changed it can effect the parts above that may consume it, or the parts below that it may consume. Since the food web relies on balance and a hierarchy, if something changes it could disrupt the balance and flow of energy in the food web.
