Answer: are the source of new genetic variation

Explanation:

Mutations are the alterations that occur in the genome of an organism.

The mutations can be caused either due to intrinsic factors such as replication error or extrinsic factors such as exposure to mutagens.
Genetic variations are the differences in the genome sequence of individuals in a given population and it occurs mainly due to two processes :

1. Mutation

2. Genetic recombiantion.

In the Hershey-Chase experiment, the material that entered cells upon infection by T2 virus was labeled with which radioactive i

Lesechka [4]

The Hershey–Chase experiment was based on a bacteriophage T2 (a virus), to that DNA is the genetic material. Bacteriophage T2 attacks bacterium and makes its copies. Based on the experiment, Hershey and Chase deduced that it is the DNA of virus enters bacteria to make virus copies. To trace viral DNA, Hershey and Chase label DNA with ³²P (radioisotope of phosphorus) because phosphorus is not present in most of the proteins.

Tall plants are dominant over short plants. One parent is homozygous dominant and the other is heterozygous for plant height.

Greeley [361]

Answer:

a. all tall

Explanation:

If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.

Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent who is heterozygous will be Tt.

The cross is depicted in the attachment.

Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.
