) Consider a pea plant- it has a gene controlling seed color- yellow Vs green; another gene controlling seed texture-smooth Vs w
lana [24]

Answer:

Yellow smooth  - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1

Explanation:

Let the green color of the seed be depicted by "G" and the yellow color of the seed be depicted by "g"

Let the smooth the seed be depicted by "R" and wrinkled seed be depicted by "r"

F1 cross -  

true breeding smooth green plant ( RRGG) and true breeding wrinkled yellow (rrgg)

F1 gamete will be RG, RG, rg, rg

F1 offspring will be RrGg , Thus all F1 offspring will be heterozygous smooth and yellow.  

Thus,  R is dominant over r and g is dominant over G

F2 Generation –  

RrGg x RrGg

Gametes will be RG, Rg, rG, rg

RG         Rg          rG           rg

RG RRGG RRGg RrGG RrGg

Rg RRGg RRgg RrGg Rrgg

rG RrGG RrGg rrGG rrGg

rg RrGg Rrgg rrGg rrgg

R is dominant over r and g is dominant over G

Genotypes are –  

RRGG - 1  (Smooth Green)

RRGg-2  (Smooth yellow)

RrGG-2  (Smooth Green)

RrGg-4  (Smooth yellow)

RRgg- 1  (smooth yellow)

Rrgg – 2  (Smooth yellow)

rrGG – 1  (wrinkled Green)

rrGg – 2  (Wrinkled yellow)

rrgg – 1  (wrinkled yellow)

Yellow smooth  - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1

Answer and explain plz:)
Gekata [30.6K]

Hey There!!

The answer to this is: C) a factor that may affect an experiment or investigation. This is the best answer. A and B can be eliminated. D describes a controlled variable which is more specific than a scientific variable, thus C is the best answer. It is the best description of just a scientific variable. And, The second one is B: Robert Hooke was a famous scientist who experimented with springs (metal coils). He found that the farther you stretched the spring, the larger the force with which the spring pulled back on you.

Hope It Helped!~ ♡

A population of walleye increased from 1200 to 3700 from 2004 to 2006 what is the Growth rate?
Varvara68 [4.7K]

Answer:

The growth rate is 1250 per year.

Explanation:

  • First of all, lets consider the population number in both years;

The initial population is 1200, and

Final population is 3700.

  • Total increased population is (3700- 1200) = 2500

So 2500 population were increased in (2006 - 2004)= 2 years.

  • To find the annual growth rate: (Increased population/ time span in years)= 2500/2= 1250 per year.
  • Hence 1250 population was added per year in walleye from 2004 to 2006.

Which is biotic?<br> wind<br> iron gate<br> sunlight<br> dead leaf
Masja [62]

Answer:

The answer is "dead leaf."

Explanation:

Although dead leaves are no longer alive, they were considered as once part of a living entity. Therefore, dead leaves are biotic factors. Wind, iron gates, and sunlight are not biotic components because they are the non-living parts of the environment that influence biotic factors. Hope this helps.
