Jennifer is trying to determine the blood type of her parents for biology class. she knows that her blood type is ab. after asking her mother, she finds out that her mother's blood type is a. however, her father cannot remember his blood type. which of the following blood types could her father have? i. a ii. b iii. ab iv. o

According to biology, each father inherits one of his alleles to his son (A, B, AB O).

The theory tells us that an AB type father can pass an A or a B to his son, there are 16 possibilities that parents can inherit their son but according to tables most likely

Jennifer is AB

If the mother is A, the father could be B

I hope its help you

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

a- all cells come from pre-existing cells
