Mendel crossed peas having round seeds and yellow cotyledons (seed leaves) with peas having wrinkled seeds and green cotyledons.
Kruka [31]

Answer:

Let:

Y = Yellow           R = Round

y = green             r = Wrinkled

If you look at the F1 generation, all the plants are round and yellow, so these are the dominant traits and each offspring is heterozygous for both traits. The cross for the F2 generation would then be:

<em>YyRr x YyRr</em>

In a Punnett it would look like the attached picture.

For the forked-line diagram, first you will need to know the gentypes and ratio of each trait in a monohybrid cross. Select one trait, and then branch each gentype to the next trait, linking it with each possible genotype combination of the monohybrid cross.

Attached is a picture of the Forked Branch diagram for this cross.

Some types of fish can generate an electric field around their body to communicate with other individuals of the same species (l
olchik [2.2K]

Answer:

D. physiological mechanisms are the basis of behaviors.

Explanation:

The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment. This way of communicating is called  electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.

How do trees know when to shed their leaves
Leona [35]
<span>The connections between cells become weakened, and the leaves break off with time. Many trees and shrubs lose their leaves when they are still very colorful. Some plants retain a great deal of their foliage through much of the winter, but the leaves do not retain their color for long.</span>

HELP PLS I WILL GIVE LOTS OF POINTS pls answer good and i will give brainliest and give more points if its correct
Fofino [41]

Answer: .374 and .626

Explanation:

5. total number of alleles = 4712 + 2816 = 7528

       frequencey of B allele = B allele / total number of alleles --> 2816/7528 = 0.374                

             

6. total number of alleles =  4712 + 2816 = 7528

   freq of b allele = b allele/total number of alleles --> 4712/7528 = 0.626

We can confirm our answer as correct because if we add up the answers to 5 and 6 we should get one:

0.374 + 0.626 = 1
