A researcher is studying linkage between singed bristles and vestigial wings, and conducted crosses between two different strain
Alex Ar [27]

Answer:

D.Singed bristles/vestigial wings and normal bristles/normal wings

Explanation:

Parent 1: singed bristles and normal wings ( ssLL )

Parent 2: normal bristles and vestigial wings (SSll)

ssLL X SSll =

F1: SsLl ( normal wings and normal bristles )

SsLl X ssll =

F2:

Sl/sl = normal bristles and vestigial wings = Parental

sL/sl = singed bristles and normal wings = Parental

SL/sl = normal bristles and normal wings = Recombinant

sl/sl = singed bristles and vestigial wings = Recombinant

since, singed bristles/ vesitigal wings and normal bristles/normal wings are different from parental combinations, they are the recombinant offspring.

A widows Peak is dominant over straight hairline the genotypes of The Offspring are WW, Ww, ww and ww. What are the phenotypes o
anastassius [24]

Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.

The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).

A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).

So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.

For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.

Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.

Answer:

chemical energy

Explanation:

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
