: Instructions: Complete numbers 1 through 8.

1. When completing this pedigree with X-linked recessive inheritance, use the CIRCLES AS

FEMALE, USE THE SQUARES AS MALE.

2. The X chromosome will contain the allele for the recessive linked trait.

3. The Y chromosome will have NO alleles for the trait.

4. Shaded circles are the females that have the recessive phenotype and have the genotype of

XrXr

é

5. Unshaded circles will represent the female who is a carrier for the recessive

sorry, but you do not have posted the diagram.

airlines i think? or a cruise boat? does this work out for u? ?

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
