makvit [3.9K]

Answer:

The model showing the condition must represent a recombination between the X and Y chromosome during meiosis in male.

Explanation:

In males, the sex chromosomes are X and Y, whereas, the females have XX chromosomes. When the X chromosome of males fuses with the female gamete it give rise to a female progeny.

The Sry gene is present on the Y chromosome. In some cases, the recombination between the X and Y chromosome during meiosis in males takes place and result in an X chromosome containing Sry gene. This Sry gene is responsible for the male characters and progeny carrying two X chromosomes, in which one has the Sry gene would have the male characters.

So, the in this case should represented the crossing over between the X and Y chromosomes in males and then passing of the Sry containing X chromosome to progeny.

The evolution of H. floresiensis is an example of island dwarfism.

Explanation:

H. floresiensis is a species of hominid. It differs significantly than the other hominid species in size though, as it appears to be a dwarfed version of its ancestors and close relatives. Its alleged ancestor is literary twice taller, which brings in the question as to what has triggered such an evolutionary adaptation.

This hominid species lived only on a relatively small island, in isolation. The resources are very limited, and the climate is warm and humid all year around. As seen in many species of animals, when individuals get into such an environment, they tend to experience either island dwarfism, or island gigantism. The island dwarfism tends to be common among large and medium sized species, while the island gigantism tends to be more common among the small species.

When the ancestors of H. floresiensis ended up in this environment, it was advantageous for them to smaller. The reason for that is that smaller bodies require less nutrition, and are also producing less heat.
