In beta fish, a blue tail (B) is dominant over a black tail (b) and a metallic sheen (M) is dominant over no metallic sheen (m). A female beta fish who is heterozygous for blue tail with no metallic
sheen has offspring with a male who has a black tail and has no metallic sheen. What is the
phenotypic ratio of their offspring?

D) 8 blue tail nonmetallic: 8 black tail nonmetallic

Explanation:

The first thing to realize about the problem is that all offspring will be nonmetallic. Both parents are pure recessive for nonmetallic tails; therefore, their offspring cannot have metallic tails. So to find the ratio, use a simple punnet square with Bb and bb. This results in a 50% chance of Bb (blue) and 50% bb (black). So the last answer is correct.

answer; i believe is(b)converging

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
