Ipatiy [6.2K]

Answer:

<em>Yes, the following description is true.</em>

Explanation:

Hemophilia is a sex-linked recessive disorder. This means that only one allele recessive allele for the trait in males will cause the disease to occur in males. However, for females, there should be two recessive alleles present for the gene for the trait to occur. A female carrying one recessive allele for the trait will be a carrier.

If a father is hemophiliac, this will mean that all the daughters will be carriers for the disease as they will have one of the allele for the trait from the father. On the other hand, about half of the sons will have the disease if they get the recessive allele from the father for the trait.

Ammonites were common during the Mesozoic Era (245 to 65 mya), but were not found after the Cretaceous period. They went extinct during the K-T extinction (65 mya)

Brachiopods which are mollusk-like marine animals appeared during the Cambrian (540 to 500 mya). Some types of them still survive

Grapolithina which are widespread colonial marine hemichordates that also lived during the Cambrian period.

Nanofossils are microscopic fossils which are remains of calcareous nannoplankton, coccolithophores from various eras

Trilobites were common during the Paleozoic Era (540 to 245 mya); about half of the Paleozoic fossils are Trilobites. Trilobites evolved at the beginning of the Paleozoic Era and went extinct somewhere in the late Permian period which was 248 million years ago
