The pedigree shows the inheritance of free earlobes and attached earlobes in five generations of a family. Attached earlobes is caused by a recessive allele (f). Half-shaded symbols are NOT used in this pedigree to show carriers of the allele.

@jgirl128 this is it :d

jgirl128 · Answer

because the 1 male passed it on to the 4 female. then because she was with a dominant free earlobe, they didn't have any offspring that had attached earlobes but they did carry the recessive gene. so then because the 8 male and the 9 female carried the recessive gene, they passed it on to their offspring. even though the attached earlobe trait is the recessive trait, it can still be the trait that's exhibited.

superhelp101 · Answer

@jgirl128 so i see what you are saying but if you say simply individual 14 is male with attached earlobes would that just be incorrect or a incomplete answer ?

Oh man, just 15 min too late!
I coulda helped, I just did much harder problems like these yesterday.

jgirl128 · Answer

no, I'd say that's right. you can assume it's male because it's a square and because it looks like the male gender is dominant in that family. and now because of the 10-13 offspring, the attached earlobes become the dominant trait

jgirl128 · Answer

what do you think bio?
