Question

You have round polka dotted (round is dominant), and you cross this with a round solid (solid is recessive) mouse. Show all possibilities with the Punnett squares of possible offspring. Polydactyl (6 fingers) is a dominant trait, but appear less than 1% of the population. Let's assume that P = .01 and p = .99----set up a Punnett square and show all probabilities of genotypes and phenotypes. Roan horses re formed from true breeding red and white horses. Show this in a Punnett square. What is the most likely explanation for the trait above and why? What is the most likely trait and why?

Explanation / Answer

8ANS:) the allele that causes roan colour is dominant and heterozygous. the arrow mark which u showing is roan horse.

7ANS:)

P p

probability of phenotype =1/4

probability of genotypeb =1/4
