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

gogolik [260]

Answer:

187.5 or rounded off to 188 white, terminal flowers

Explanation:

Let red=R and white=r where R>r; axial=A and terminal=a where A>a

The parents are true-breeding which means that they are homozygous.

P: RRAA x rraa

F1: RrAa

We then cross two plants from the F1 generation

RrAa x RrAa

To find out the probability we look at the different traits individually

Rr x Rr

yielding 1/4 RR (red), 1/2 Rr (red), 1/4 rr (white)

Aa x Aa

yielding 1/4 AA (axial), 1/2 Aa (axial), 1/4 aa (terminal).

We determine which F2 genotypes would allow for red, terminal flowers.

RRaa and Rraa

Then we use the multiplication rule to determine the probability of these occurring

RRaa: 1/4 x 1/4 = 1/16

Rraa: 1/2 x 1/4 = 1/8

Next we use the addition rule

1/16 + 1/8 = 3/16

To find out the number of these plants within the 1000 F2 plants we multiply the probability with 1000

3/16 x 1000= 187.5 red, terminal flowers

What is myofascial and it's massage?

The method focuses on pain that is thought to originate in your muscles' tough membranes known as myofascial tissues, which wrap, link, and support your muscles. Myofascial pain, which is related to "trigger points," which are associated with stiff, anchored places inside the myofascial tissue, theoretically varies from other types of pain.

A stimulation, such as muscle stiffness, that activates trigger points in your muscles is what causes myofascial pain syndrome. The following elements may raise your risk of developing muscle trigger points: muscle harm. Trigger points can form as a result of a recent muscular injury or ongoing muscle stress.
