F1 generation: RrUu, rrUU, rrUu, RrUU

25% : 25%: 25%: 25%

Ratios

genotype: 1: 1: 1: 1 ...(from punnet square)
phenotype: 1 : 1

Explanation:

Punnett squares are a diagrammatic way of deciding the characteristics of hybrid offspring created by crosses in genetic breeding. Parental genotypes and phenotypes are widely recognized, and all usually obey normal Mendelian ratios and inheritance.

Mendelian genetics focuses on the origin or heritability of characteristics. Such traits are packed into one's own gamete, acquired by themselves, and sometimes display superiority, where one's impact can mask those of another trait.

These are called the Law of Segregation, Independent assortment and Dominance respectively.

For this cross... Assuming:

Unattached lobes= dominant

Rolling tongue= dominant
Parent generation or P generation:

Gametes:

R → rolling dominant (R), non-rolling recessive (r)

U → unattached dominant (U), attached recessive (u)

P generation: RUrU× rUru

rolling, unattached × non-rolling, unattached

F1 generation: RrUu, rrUU, rrUu, RrUU

25% : 25%: 25%: 25%

Ratios

genotype: 1: 1: 1: 1 ...(from punnet square)
phenotype: 1 : 1

Half the offspring have unattached lobes and can roll their tongues while the other half have unattached lobes and cannot roll their tongues...

Each punnet cross is attached below

Despite having access to medicare, the elderly spend about ________ of their income on health care

matrenka [14]

The answer is fifth. This is because the increase in expenditure is reflected in the increasing cost to the federal and state governments of operating the Medicare and medical programs as well as in the increase in out-of-pocket payments made by the elderly. As a consequence health care financing has become one of the more critical policy issues to be addressed.
