Answer #1

6.A

Probability of occurance of two exclusive events where final order is not specified - polity DCRJE = 12 factoral * ()* * 5fac

Total number of seeds 12. So n! is 12 factorial (12x11x10x9x8x7x6x5x4x3x2x1)

Number of white seeds =5, s! is 5 factorial (5x4x3x2x1)

Number of purple seeds = 7 , t! is 7 factorial (7x6x5x4x3x2x1)

(p)^s is (1/4 )^5 and (q) ^t is (3/4)^7

p- is phenotype of white which is 5 and q is phenotype of purple which is 7. We have only 2 phenotypes here and white has to be recessive as it has not appeared in F1 and purple is dominant. With that consideration, the probability is F2 for purple is 3/4 and probability for white is 1/4.

The probability of 5 white and 7 purple flowers in 12 seeds is 1/10 and the order of the flower color is not mentioned.

    You perform a trihybrid cross: You cross true-breeding purple-flowered, round, yellow peas (PPRRYY) with true-breeding white-flowered, wrinkled, green peas (pprryy). You then cross the resulting F1 offspring together to generate an F2 generation. What is the probability of an F2 plant having white flowers and producing round, yellow peas?

    25. A cross is made between two different true-breeding strains of daylilies, both of which have white flowers. All of the F1 generation plants have yellow flowers. When an F, offspring is crossed with either one of the parental strains, half of the offspring have yellow flowers and half of them have white flowers. Propose an explanation for this outcome. In your answer, you should describe the genotypes of the two parental strains and the F1 offspring, and also explain...

    You decide that you want to replicate some of Mendel’s original results. You begin your experiment with plants that have true breeding traits, one set of plants that have purple flowers and round seeds, the other with white flowers and wrinkled seeds. You do a cross and the progeny (F1 generation) are all purple flowering and produce round seeds. What is the probability that a cross between two F1's will yield offspring that are white and with wrinkled seeds? Seed...
