The alleles for eye color in fruit flies involves one allele that might contain the sequence CCAT. Assume that this allele produces red eyes in a fruit fly, because the allele produces a protein that makes red pigment. Assume that another allele of this gene has a slightly different sequence in the middle: CAAT, instead of CCAT.Which of the statements below is true about the alleles for eye color in fruit flies? Which of the statements below is true about the alleles for eye color in fruit flies? A) The alleles for eye color produce the same phenotype. B) The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly. C) Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population

Fish and amphibians commonly conduct fertilization.

Answers

Fish and amphibians commonly conduct fertilization externally. External fertilization occurs when the female releases the eggs into the environment and then the male releases sperm on top of the eggs.The eggs are then fertilized. Internal fertilization occurs when fertilization happens inside the female's body. After fertilization, the female either bears live young or lays eggs which hatch. Both of these processes take place after a period of incubation either internally or externally. Eggs which are externally fertilized do not have a hard external protective covering or shell. 

Why might a tapeworm have an expanded reproductive system compared to a planarian?

Answers

Tapeworms are hermaphroditic, like the Planaria. The difference between them is that Tapeworms can reproduce sexually, either through self-fertilization or cross-fertilization with another tapeworm, or asexually, by breaking off proglottid segments at the end of the trunk. While the 
Planaria are sexual and asexual only. Sexual planaria possess both testicles and ovaries. One of their gametes will combine with the gamete of another planarian. Each planarian transports its excretion to the other planarian, giving and receiving sperm. Eggs develop inside the body and are shed in capsules. Weeks later, the eggs hatch and grow into adults

What is referred to as variation?

The difference in DNA among individuals or the differences between populations is referred to as variation.

There are multiple sources of genetic variation including the following:

  • Genetic mutation.
  • Geographical isolation.
  • Reproductive isolation.
  • Environmental factors.
  • Geographical barriers.

Variation can leads to the formation of new species.

Thus, these are some factors that are responsible for the formation of new species.
