Hii I need help on three questions! 1. Oompahs with type O blood receive a tax break. Opine Oompah has Type A blood, but he wants a wife that will give him children with type O. What blood type should he request on his dating survey? What must Opine’s blood type be in order to produce offspring with type O blood?

2. Ozzie Oompah has 7 sisters and brothers. Ozzie has type AB blood, but his siblings blood type ranges from A to B to O. Given this information, determine the genotypes and phenotypes of Ozzie’s parents.

Genotype of Ozzie Oompah’s mom ___
Genotype of Ozzie Oompah’s dad _

3. In Oompahs, the allele for normal eye color is a dominant brown (XbXb) pigment. Having green eyes (Xb) among Oompahs is a rarity. This is a sex-linked trait found on the X chromosome. Zed Oompah has Green eyes (XbY). What is the phenotypic probability of his daughters and of his sons having green eyes if his wife Gigi (XbXb) is a carrier of green eyes?

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:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
