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

In Central and Northern California, the Red-legged Frog (Rana aurora) breeds from January to March. The closely related Yellow-l

The two species may experience divergent evolution due to the differences in the timing of breeding activity. Divergent evolution is associated with common ancestry.

<h3>Divergent evolution</h3>

Divergent evolution is an evolutionary process characterized by species that share a common ancestry and differentiate over time.

This type of evolutionary process (divergent evolution) is due to the different selection pressures on populations, thereby shaping evolution and speciation.

Divergent evolution may cause speciation due to the emergence of reproductive isolation barriers that hamper the mating between individuals in the population.

Transmission electron magnifying lens - The transmission electron magnifying instrument utilizes electrons rather than light. a light magnifying lens is constrained by the wavelength of light. TEMs utilize electrons as "light source" and their much lower wavelength makes it conceivable to get a determination a thousand times superior to with a light magnifying lens. The likelihood for high amplifications has made the TEM a significant instrument in both medicinal, natural and materials research.Compound light magnifying instrument - Microscope with more than one focal point and its own particular light source. There are visual focal points in the bonicular eyepieces and target focal points in a turning nosepiece nearer to the example. To determine the energy of amplification of a compund light magnifying instrument, it's expected to take the energy of the target focal point and duplicate it by the eyepiece which is by and large 10x. Albeit at times found as monocular with one visual focal point, the compound binocular magnifying lens is all the more regularly utilized today. The principal light magnifying lens goes back to 1595, when Zacharias Jansen made a compound magnifying instrument that utilized crumbling tubes and delivered amplifications up to 9X.
