In Sexual reproduction evolution takes place.

Explanation:

In sexual reproduction, the gametes from the two parents fuse to form a zygote and consequently an organism. The gametes from the two parents provide different alleles for a trait. The different genetic variant or alleles found will cause genetic variation.

The offspring can survive and adapt to the new environment. This leads to natural selection and evolution.

In asexual reproduction changes only occur if mutation takes place otherwise the progeny remains genetically identical so less chance of evolution.

Analogous are the organs having similar function but different origin in different organisms.

Detrimental effects are small or negligible effect of mutation on organism due to the exposure of chemicals or rays.

Only those mutations are heritable which occur in germ cells, mutations of somatic cell do no pass to other generation. Detrimental effect is mainly seen in somatic cells.

natulia [17]

Answer:

Answer is D "Genes for the two traits are located close together on the same chromosome, and crossing over occurred between the two gene loci"

Explanation:

Traits are distinguishing characteristics of an organism. The Phenotypic crossing of the Drosophila melanogaster specie with Gray body and long wings over that of the same specie but female with black body and apterous wings produced a total of 100 offspring, which showed a that genetic crossing were done on the closely related chromosomes of the body traits for the individual species.

Answer:

Hello, The DNA fingerprinting technique and development and comparison of physical fingerprints can be the methods used for the purpose of solving crimes and identification of missing person. The DNA fingerprinting can be done from the physical evidences such as blood, sweat, hair, tissues, teeth and other material obtain at crime scene. These can be compared with the suspects, victim and missing persons so as to establish their identity. The physical fingerprints can be developed on the scene of crime and compared with the requested specimen from suspect, victim and the missing person or in case of impersonation to establish the desired identity.

<em>Hope This Helps!</em>
