I don't know much about it but i think it is when <span>When you crosses 2 plants of the same pure lines parentage, the resulting F1 is termed as true-breeding plants.
</span>True-breeding plants can also be produced by <span> selfing </span> (or self crossing) flowers form a pure line plant. When seeds from this fertilization are planted, they will give rise to homologous-homogeneous population.

What are some disadvantages of fossil fuels?

Fed [463]

Answer:

B. Fossil fuels are nonrenewable and may cause pollution.

Explanation:

Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.

Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.

Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.

So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution

) 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
