Question

Example Problems In blue sharks, the traits : long fins (L) or short fins (l), bright blue (B) or pale blue (b), and schooling (S) or solitary (s) are located on different chromosomes. In a cross of LlBbSS x llBbSs, what is the probability of having offspring with short fins, bright blue coloration that are schooling?

Step 1

For the fin length trait (L/l), the cross is Ll x ll. The probability of having short fins (l) is 1, as all offspring will inherit the short fin allele from the parent with ll genotype. For the coloration trait (B/b), the cross is Bb x Bb. Using a Punnett Show more…
