In chickens, comb shape is determined by two independent genes (R and P). A walnut comb is produced when at least one dominant a

Aleksandr [31]

Answer:

Option B, Rr pp × rr Pp

Explanation:

Given

Walnut Comb is produces when one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*

Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp

Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second - rr P*

Single comb - two recessive alleles are present at the first and the second locus - rrpp

Parent are rose combed and pea combed

For being rose genotype must be R* pp

and for being pea combed genotype must be rr P*

Rr pp x rr Pp

will produce

Walnut comb with genotype Rr Pp

Single comb with genotype rrpp

and pea comb with genotype rrPp

Hence, option B is correct

The anterior portion of the body of most annelids, such as the earthworm, is adapted for sensing the environment.

Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are more abundant in the anterior portion of the annelid´s body, in general, they are arranged in all the segments.

Explanation:

Annelids, such as the earthworm, have a variety of sensory cells:

Mechanoreceptors, disposed of in groups in each segment of their body.

Photoreceptors: Light-sensitive cells. Although they are located in the whole body, they are abundant in anterior and posterior segments, concentrated in the intern and dorsal part of the epidermis.

Humidity receptors are the most sensitive cells and are located in the first segments of the earthworm body

Chemoreceptors: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings in each segment but are especially abundant in the anterior part of the body.

The tegument is very rich in free nervous terminations, which functions might be tactile.
