Answer:
extant; extinct.
Explanation:
A species is a group of individuals that can interbreed to produce fertile and viable progeny. A species may be present on the earth and is surviving or may not be present now on the earth and have become extinct due to one or more reasons. Extant species are the species living on the earth in the present time while extinct species do not exist now. For instance, <em>Plateosaurus engelhardti</em> is a species of dinosaurs that survived on the earth during the Triassic period but does not exist now. On the other hand, <em>Homo sapiens, Apis indica</em> are some of the examples of the extant species that are surviving on the earth.
Answer:
0.033
Explanation:
Tay–Sachs disease is an autosomal recessive disorder. The possible genotypes and phenotypes are:
- TT = normal
- Tt = carrier
- tt = Tay-Sachs disease
I will use <em>p </em>to call the frequency of the dominant <em>T</em> allele, and <em>q</em> the frequency of the recessive <em>t</em> allele.
If the population is in equilibrium, the frequency of the tt genotype is q².

The frequency of the Tt genotype is 2pq.

The Tay–Sachs carrier frequency will be 0.033
