Part 1: crossing beak color and tail-feather length cross a yyll (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits). look at the number of genotypes of the f1 generation: yyll: 400 yyll: 100 yyll: 100 yyll: 400 (score for question 1: of 2 points) which offspring are the recombinant offspring in this cross?type your answer here.

Since you forgot to put capital letters i assume it's like this:

1)A Cross between YyLl (heterozygous parent with dominant traits) and yyll (homozygous parent with recessive traits).

2)offspring YyLl: 400, Yyll: 100, yyLl: 100 and yyll: 400

The recombinant offspring are allele combinations that are not directly inherited from the parents.
The parents combinations:YyLl and yyll,
The recombinant combinations: Yyll and yyLl
The other types are exacly like the parents so they are not recombinant.

Yyll and yyLl
