Answer:

Conjugation

Explanation:

F plasmid or fertlity plasmid is an extra chromsomal circular DNA present in bacteria that are capable of independent replication. This is one of the large plasmid that are used for the transfer of genes.

F plasmid are involved in the process of conjugation. Conjugation is the process of transfer of genetic material by the direct contact of the cell. The tra genes are responsible for the transfer of F plasmid. The F plasmid is transferred from the donor bacterium to the recipient bacteria that do not contain F plasmid during conjugation.

Thus, the correct answer is option (1).

A plant breeder has determined the following variances for yield of corn in his fields:

Law Incorporation [45]

Answer:

A. VG = 80

B. Broad sense heritability = 0.80

C. Narrow sense heritability = 0.30

D. Average yield = 430 Units

Explanation:

A. Given that

VA = 30

VD = 50

VI = assumed not available

Therefore

Total genetic variance (VG) = VA + VD

= 30 + 50

= 80

VG = 80

B. Given that

VP = 100

VG = 80

Broad sense heritability, H2 = VG/VP

= 80/100

= 0.80

C. Given that

VA = 30

VP = 100

Narrow sense heritability, h2 = VA/VP

=30/100

= 0.30

D. The difference in selection = 500 - 400

= 100

Recall,

Selection response is heritability multiplied by selection differential.

That is

R = h2S

Selection differential = 100

Heritability h2 = 0.30

Selection response = 0.30 × 100

= 30units

Therefore, expected average yield = 400 + 30

= 430 Units
