Brown hair is dominant over red hair. What will the genotypes and phenotypes of the offspring of a cross between a homozygous br
bija089 [108]

Answer:

1) Firstly, lets sort out the alleles for the dominant and recessive characteristics. The dominant brown allele will be written as B and the recessive red hair allele will be written as b.

2) Lets sort out the genotype of the parents. The parent having homozygous brown coloured hair will carry the alleles BB. The parent carrying the heterozygous brown coloured hair will carry the alleles Bb.

3) The punnet square from these parents will be drawn as follows:

      B        b

B    BB     Bb

B    BB     Bb

4) Now, lets predict the phenotype of the offsprings. The results from the punnet square show that all of the offsprings will have brown coloured hair.

5) The genotype for the children will have 50% chance to be homozygous brown (BB) and 50% chance to be heterozygous brown (Bb).

What is the advantage of radial symmetry for sessile animals such as hydras and bilateral symmetry for mobile animals such as pl
Juliette [100K]

Answer:

- Radial symmetry is advantageous because sessile animals can "sit down", take food, or sense harmful environmental conditions from different directions.  

- Bilateral symmetry allows motile animals to move straight forward.

- The major evolutionary advantages of bilateral symmetry include cephalization, the formation of a head and tail area and a more directional motion.

Explanation:

Radial symmetry is advantageous for sessile organisms since it enables the uniform distribution of the sensory receptors around the body. In consequence, sessile organisms can react to environmental stimuli from every direction. On the other hand, bilateral symmetry allows motile organisms the arrangement of a specialized nervous system from the anterior end of the organism (i.e., the 'head'). Moreover, another important advantage of bilateral symmetry is the ability to equalize environmental pressures on both sides of the body, thereby enabling a rectilinear motion.
