The dominant trait is hornless.
If this is correct, then the original bull is a heterozygote:
H = hornless
h = horned
Bull is Hh
Cross 1: Hh x hh (horned female) - offspring is hh (horned)
Cross 2: Hh x Hh (hornless female) - offspring is hh (horned)
Cross 3: Hh x hh (horned female) - offspring is Hh (hornless)
Cross 3 is the key to confirming this because the only way to get a hornless offspring would be if hornless is recessive.
The nurse may say something along the lines of "The order will be submitted to your physician. Your parents will not know." It is only a simple test to see whether the boy has contracted the Human Immuno-Deficiency virus, and thus is not anything that requires interference on the parents' part, which may bring embarrassment on the adolescent. The nurse is practicing general ethics and her moral code here.
In some protists, genetic information is transferred from one cell to the next. This transfer is called _____. A. external fertilization.
Answer:
The different species present in an ecosystem make the ecosystem balanced. The species of an ecosystem interact with one another in one form or the other. For example, the presence of a plant species will provide food for the abundant types of herbivores present in an ecosystem. A predator might feed on many types of preys. Hence, the presence of different preys will reduce the chances of a species from becoming wiped out from the ecosystem. Hence, all the organisms in an ecosystem are dependent on another in some way or the other.
