Answer:
The correct answer is e. <em>Postzygotic barrier.</em>
Explanation:
Different species can not mate and produce viable, healthy and fertile descendence, due to certain mechanisms of <u>reproductive isolation</u>.
These mechanisms involve different kinds of barriers that make it difficult for two different species to produce viable and fertile progeny.
One of these is the <u>postzygotic barrier</u>, which avoids the hybrid zygote to develope to adultness. In these situations, there is a mix of chromosomes that can not happen to meet or that they lack information.
There are cases in which the embryo dies, but some times the individual can reach some more advanced develope stages. If this is the case, in general, they can not survive because the organism is unhealthy. And if they reach adultness in good sate they can not leave descendence, as they are sterile.
A bonds to T and C bonds to G so it would be AGTTCA
EPDs are computed using production data that registered seedstock members have provided to the breed organizations. Based on ancestral data, individual performance data, and progeny data as they become available, this information is entered into statistical matrices to generate the estimated Page 2 breeding values of animals.
