If pink flowers are crossed with white flowers and all offspring are pink, which of these is most likely to be true? * Captionless Image
The white allele is dominant.
The pink allele is dominant.
White and pink alleles are codominant.
White genes were not passed on.

The answer is 25% red : 50% pink : 25% white

A - allele for red flowers

a - allele for white flowers

AA - flowers with red flowers

Aa - flowers with pink flowers

aa - flowers with white flowers

The cross looks like:

Parents:          Aa     x     Aa

Offspring:    AA    Aa   Aa    aa

Red flowers (AA): 1/4 = 0.25 = 25%

Pink flowers (Aa): 2/4 = 0.50 = 50%

White flowers (a): 1/4 = 0.25 = 25%

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
