Hey There! PEA PLANT:

Pea plant has Round Seed dominant over Wrinkled Seed.

Round Seed allele is R

Wrinkled Seed allele is p

CONDITIONS:

Hom.ozygous Dominant Alleles: RR (Round Seed)

Heter.ozygous Dominant Alleles: Rr (Round Seed)

Hom.ozygous Recessive Alleles: rr (Wrinkled Seed)

CROSS I:

Whenever we cross Heter.ozygous Dominant(Rr) with Hom.ozygous recessive (rr), we get 50% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is Rr

The P2 is rr

When we cross them,

It has 4 offsprings,

Rr Round Seed

rr Wrinkled Seed

Thus the answer is 50% round seed as there are 2 out of 4 heter.ozygous dominant round seed.

CROSS II:

Whenever we cross Hete.rozygous Dominant(Rr) with another Heter.ozygous Dominant (Rr), we get 75% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is Rr

The P2 is Rr

When we cross them,

It has 4 offsprings,

RR Round Seed

Rr Round Seed

Rr Wrinkled Seed

rr Wrinkled Seed

Thus the answer is 75% round seed as there are 3 out of 4 hom.ozygous and hete.rozygous dominant round seed.

CROSS 3:

Whenever we cross Homo.zygous Dominant(RR) with Heter.ozygous Dominant (Rr), we get 100% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is RrR

The P2 is Rr

When we cross them,

It has 4 offsprings,

RR Round Seed

Rr Wrinkled Seed

Thus the answer is 100% round seed as there are 4 out of 4 hetero.zygous and homo.zygous dom.inant round seed.

Answer from: Quest

c. live where it’s cold and icy

Answer from: Quest

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
