Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers, and the other has white, terminal flowers

Debora [2.8K]

Answer:

Explanation:

The probability of producing plants with white axial flowers would be 1/16.

From the illustration, All F1 individuals had red, axial flowers. It thus means that red and axial genes are dominant over white and terminal genes in the pea plant.

Let us assume that the allele for flower color is A (red) and a (white); and the allele for flower location is B (axial) and b (terminal).

Pure-breeding red, axial flower = AABB

Pure breeding white, terminal flower = aabb

AABB x aabb

F1 genotype = AaBb - all red and axial

At F2:

AaBb x AaBb

Progeny

9 A_B_ red/axial

3 A_bb red/terminal

3 aaB_ white/axial

1 aabb - white/terminal

Hence, the probability of producing plants with white axial flowers in the F2 generation is 1/16.

Which two factors contributed to creating a truly global culture? a decrease in population growth rate improvements in telecommu

lora16 [44]

Answer:

1. Improvements in telecommunication

2. Improvements in global travel

Explanation:

Global culture refers to the transmission of beliefs, values, and ideas around the world that has a significant impact in the behavior of society. This has been evolving through time, especially since the Industrial Revolution. Today, we are capable of communicating with other people as quickly and easy as ever in the history of humanity and this will keep evolving as technology evolves as well.

This evolution is due to science and technology, especially to the improvements in telecommunication, which enables us to communicate with people from other countries through calls, social media messagings, e-mails, etc., and to the improvements in global travel, which is much more accessible today than it was before, allowing individuals to move from one country to the other easily and constantly and improving socialization between people from different cultures and backgrounds.

You work for the WWF. Write a letter to the mayor of a small farm town to explain why this town is experiencing erosion, and why

horrorfan [7]

The letter should contain concerns about the causes and ill effects of erosion.

<h3>Explanation:</h3>

Sir,

I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.

The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.

So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.

Thanking you,

XYZ.

In a two-point test cross, 36 of the offspring were recombinant types. The remaining 64 offspring were parental types. How many

Maksim231197 [3]

Answer:

Explanation:

A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
