If a heterozygous male for B type blood has a child with O type blood, what are the only possible genotypes that the mother can have to create a child with O type blood? Question 2 options:

Mother can be either heterozygous B blood or O type blood

Mother can be either heterozygous B or A blood or O type blood

Mother could have any combination, if the child has one "i" allele for O type blood, they will have O blood regardless of what the other allele is.

More information is needed, this is not able to be determined.

there is no

explanation:

d. groundwater flows through the subsoil and deposits minerals.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
