The stage runs from the 5th through the 10th week of pregnancy

The first two weeks after conception are known as the germinal stage, the third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.

<h3>What is Embryonic period ?</h3>

Approximately four weeks after conception, the neural tube forms. This tube will later develop into the central nervous system including the spinal cord and brain.

The neural tube begins to form along with an area known as the neural plate.

Each layer gives rise to specific tissues and organs in the developing embryo thus, the correct sequence is: Zygote --> Morula --> Blastula --> Gastrula --> Embryo.

7. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white

kondor19780726 [428]

Answer:

See the answer below

Explanation:

Genotype is the genetic composition of organisms and a gene is made up of two alleles.

a) Since the allele for black is B, the genotype for black chickens would be BB.

b) Since the allele for white is W, the genotype for white chickens would be WW.

c) Since erminette color is heterozygous, the genotype would be BW.

d) Two erminette were crossed:

BW x BW

BB BW BW WW

i. Probability of having black chick (BB) = 1/4

ii. Probability of having a white chick (WW) = 1/4

iii. Probability of having erminette chicken (BW) = 1/2

Describe the means by which Hershey and Chase established that only the DNA of a phage enters an E. coli cell. What conclusions

ASHA 777 [7]

Answer:

Harshey and chase labeled T2 bacteriophage with radioactive sulfur and radioactive phosphorus. As DNA contains phosphorus, not protein and protein contain sulfur, not phosphorus, therefore, the presence of radioactivity in cell can determine which is the genetic material .

Then Harshey and Chase infected E.coli with T2 bacteriophage and centrifuged the cell. They found radioactive phosphorus in cell pellet and radioactive sulfur in supernatant.

So by this experiment, they concluded and proved that DNA is the genetic material that gets transfer from one generation to another.
