When both parents are heterozygous for seed shape (Rr, where R is the allele for round seeds and r is the allele for wrinkled seeds), the probability of producing an offspring with round seeds can be determined using a Punnett square. The possible genotypes are RR, Rr, Rr, and rr. Thus, there are three combinations (RR and Rr) that result in round seeds out of four total combinations. Therefore, the probability of having an offspring with round seeds is 3 out of 4, or 75%.
The probability that an offspring will have wrinkled seeds is 2 in 4 or 50%
if the unit digit ie the '3' in 53 is less than 5, round down - if the unit digit is 5 -9 you round up.. Examples... 41 - round down to 40 67 - round up to 70 59 - round up to 60 33 - round down to 30 56 - round up to 60 75 - round up to 80
You would round it UP - to 70
lets say you have the number 0.254 to round it to the nearest fourth you round it to 0.25 4 and below round down 5 and up round up
