When modelling the inheritance of ABO blood types, A and B are equally dominate to O. with regard to the Rhesus blood type, Rh+ is dominate to Rh+... 8
If the individual above mates with one with the Hb+Hb- Rh+Rh- genotype, what is the probability that they can produce an offspring with type A positive blood and have acute anemia? .09
Adult fig trees produce seeds
We learned in class of an unusual group of butterflies(Heliconius spp.) that collect pollen and nectar. They have co-evolved with a group of vines in the squash family. which of the following is true? the vines produce an inflorescence that will, over an extended period of time, provide the butterflies with male flowers from which pollen and nectar are harvested.

The "biological species concept" offers us a practical way to distinguish species of organisms and to assign individuals to one taxon or another. In order to catalog individuals as being members of one species or another using this concept focuses on the ability of individuals to successfully interbreed with each other.
Mules develop from the interspecific breeding of a female horse and a male donkey. All male hybrids and most female hybrids are sterile. Horses have 32 pairs of chromosomes; donkeys have 31 pairs. which of the ff is not true? During meiosis in the case of donkey, at the stage when crossing over occurs, there are 128 chromatids.
in the movie, "Eternal Arms Race" we observed a predatory fish attempting to feed on a mussel. The mussel makes use of the fish as an "incubator" for its young.
When a female horse hybridizes with a male donkey, a mule is the result. Mules are perfectly healthy but cannot produce offspring. This is probably cus the chromosome inherited from the horse do not pair properly with those of the donkey during meiosis.

There is evidence that one or perhaps two individuals of one species of finch originally colonized the Galapagos islands, and more specifically San Cristobal Island on the eastern end of the archipelago. since that time.. There is less diversity in the mitochondrial DNA of finches on San Cristobal than among their finch ancestors remaining in the Americas.
The figure indicates that there is a relationship between the geographic distance.. which of the following statements does not sound reasonable? differences in the levels of inbreeding and genetic drift are most likely the cause in the differences in the reproductive isolation
In class we talked about the breed of dogs known as mexican hairless.. Inheritance of hair can be simply modeled as: the frequency of the "- -" would diminish but not be entirely lost,
Europeans introduced rabbits to Australia. Absent natural "enemies" their numbers grew unchecked. In the 1950s, the blood-borne myxoma virus was introduced to Australian.. b and c are true

In New Guinea, Vogelkop bowerbirds erect bowers of sticks that are stacked about a central tree. One of the two populations that is found at different locations on one of the islands constructs bowers... the population of bower birds appear to be reproductively isolated
In the example of species formation involving flies that feed on fruit in Wisconsin, the two populations of flies are kept reproductively isolated because they find different fruits acceptable as stages for courtship dances
The Andes Mountains of S.America began forming prior to the range that bisects C.America. As this happened, the distribution of the Ancestors of today's Bushmaster snakes became divided.... the snakes from eastern and western Costa Rica are more likely to breed successfully and have viable offspring than if either breeds with the South American snakes.
Some species of acacia trees have symbiotic relationships with ants. Which of the ff is not true? The plant has nectar producing glands along its stems

The hawkmoth has coevolved with the orchid such that the moth has an unusually long proboscis and the orchid has an unusually long floral tube. Which of the ff is correct? nectar is likely to be found in the long floral tube
Most populations of potentially interbreeding individuals are relatively small, unlike the infinitely-large populations of the Hardy-Weinberg equilibrium.. Which of the ff is a likely result of the heightened inbreeding in a small population, compared with a Hardy Weinberg population? The frequency of homozygous genotypes would increase
In order for a population to not change its genetic makeup and therefore maintain the Hardy-Weinberg equilibrium, all of the ff must be true of the population except for which one? there must be no inbreeding
Red-green color blindness is a X-linked recessive characteristic. Hemophilia is similarly a X-linked recessive characteristic. If a color-blind man without hemophilia fathers a child with a woman who is a carrier of both recessive characteristics, which of the ff is true? (assume no cross over) the probability that they will produce a son suffering from both disorders is .25 if one of the mother's X chromosomes has both recessive alleles.
