4. What information would allow you to distinguish between homologous vs. analogous (AKA homoplastic) traits, or to decide wheth
aleksandr82 [10.1K]

Answer:

Homologies - phenotypic and genetic similarities due to shared ancestry

Analogies (homoplastic) - similarities between two species due to convergent evolution instead of descent from a common ancestor with the same trait

In general, organisms that share very similar morphologies or similar DNA sequences are likely to be more closely related than organisms with vastly different structures or sequences. In some cases, however, the morphological divergence between related species can be great and their genetic divergence small (or vice versa).

(plants very different, bc diverged 50 mil years ago)

If internal anatomy, physiology, and reproductive systems are very dissimilar, probably analogous.

The more elements that are similar in two complex structures, the more likely it is that the structures evolved from a common ancestor. If genes in two organisms share many portions of their nucleotide sequences, it is likely that the genes are homologous.:

Match the reproductive structures based on their function and the system to which they belong.
Rashid [163]

Complete question: Find the complete question in the attached file below.

Answer: From the question, the system to which the structures belong are:

Female reproductive structures include: Egg, ovary, fallopian tube, vagina.

Male reproductive structures include: Urethra, sperm, testis, Vas deferens

Explanation:

The female reproductive system is made up of structures, listed above, which functions together with the purpose of reproducing offsprings. Below is the structure matched with the correct function from the question given:

--> Egg: This functions as the sex cell or gamete

--> ovary: The site where gamete are produced

--> Fallopian tube: This functions to transport the gamete from the site of production in the reproductive system

--> Vagina: connects the internal reproductive fluids to the exterior.

The male reproductive system are also made up of structures that functions together to bring about the fertilization of the female sex cell. Below is the structure matched with the correct function from the question given:

--> Urethra: connects the internal reproductive fluids to the exterior.

--> Sperm:This functions as the sex cell or gamete

--> Testis: The site where gamete are produced

--> Vas deferens: This functions to transport the gamete from the site of production in the reproductive system.
