Answer:

The percentage of the offspring that will be expected to have the TTYy allele combination is 25%.

What is punnet square?

A cross or breeding experiment's genotypes can be predicted using the Punnett square, a diagram with squares. This square bears Reginald C. Punnett's name, who created this invention in 1905.

Two heterozygous plant crosses will result:

  T         T                        Y         y

T   TT     TT                   y   Yy     yy

t    Tt       Tt                   y   Yy      yy

The ratio of TT =   1/2     The ratio of Yy =  1/2

The total ratio of TTYy is 1/2 x 1/2 = 1/4 = 25%.

Therefore, 25% of the progeny should carry the TTYy allele combination, according to expectations. The offspring produced is heterozygous.

Which describes the relationship between a genotype, a phenotype, and an organism’s experiences?

Answers

the one that describes the relationship between a genotype, a phenotype, and an organism’s experiences would be:A genotype is an organism's allele combination. A phenotype is the physical appearance of a trait in an organism, which may be influenced by the organism’s experiences.A genotype exist since birth and couldn;t be influenced by anything else, meanwhile a phenotype that an organism have will be influenced by a lot of external factors
We are asked to describe the relationship between a genotype, a phenotype, and an organism's experiences. The answer is that the genotype pertains to an organism's allele combination while a phenotype is the physical features which may be influenced by an organism's experience.

Complete the sentence with the correct information. One of the big advantages to a 401(k) plan is that ______.a. 401(k) plans are rare enough that they are very valuable
b. the plan automatically increases in value by 500%
c. you don’t have to pay into a 401(k) with your own money
d. the amount you contribute reduces your taxable income

Answers

d. the amount you contribute reduces your taxable income

A 401(k) is a retirement savings plan sponsored by an employer. It lets workers save and invest a piece of their paycheck before taxes are taken out. Taxes aren't paid until the money is withdrawn from the account.

One of the big advantages to a 401(k) plan is that the amount you contribute reduces your taxable income. The correct answer is (d).

A plan is a detailed proposal for achieving a specific goal or objective. It typically involves outlining a series of steps or actions that need to be taken in order to achieve the desired outcome.

One of the big advantages to a 401(k) plan is that the amount you contribute reduces your taxable income.

  • This means that the money you put into your 401(k) is deducted from your taxable income, which can lower the amount of income tax you owe.
  • Additionally, many employers offer matching contributions to employees' 401(k) plans, which can help to grow your retirement savings even faster.
  • In general, 401(k) plans are a popular way for people to save for retirement because they offer a tax-advantaged way to invest in the stock market or other investment vehicles.

Therefore, the correct answer is option d. the amount you contribute reduces your taxable income.
