Question A, B, O blood types in humans demonstrate the phenomena known as co-dominance. The blood Rh factor (+ or -) displays an inheritance pattern of simple dominance. Using the following designations: A as the dominant allele for blood type A, B as the dominant allele for blood type B and o as the recessive allele for blood type O and R as the dominant (+) Rh allele and r as the recessive (-) Rh allele, what are all of the possible genotypes for the following blood types. a) A+
b) O+
c) B-
d) AB-
e) If one parent has the blood type A+ and another parent has O+ blood, what are the possible blood types of their children?

4.06 hc)a five-year review of threats to the southern resident orca population of the united states concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. how might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters? a)the transient population is more likely to be affected by contaminants. b)the transient population is less likely to be affected by whale watching vessels. c)the transient population is more likely to be affected by disease. d)the transient population is less likely to be affected by prey availability.

How are the reproductive cycles of a fungus and a pteridophyte similar? a)both organisms form fruiting bodies that produce diploid seeds. b)both organisms produce haploid spores and exhibit diploid and haploid stages. c)both organisms reproduce sexually when two haploid hyphae fuse. d)both organisms exhibit a diploid stage and are only able to reproduce asexually.
