Explanation:
1. As shown in the punnet square below, the offprings can have the following genotypes; AA, AO. AB, and BO. The phenotypes of the offsprings will therefore have blood types; A , AB and B.
2. A pedigree is a tree that shows the family history of an individual. In the lineage, one can discover that a particular disorder is transmitted by a certain gender, which is most often the males. This is how sex-linked disorders are indentified.
3. The Y chromosoms have very few genes and does not match the X chromosome allele for allele. Therefore a recessive gene on the X chromosome in males is likely to be expressed than in females because females have an extra X crhomosome.
4. The dominant allele is always expressed over the recessive one even when both are present (heterozygous) in an individual. Only when both aleles are recesive will the recessive trait be expressed.
5. Incomplete dominance means none of the alleles have complete dominance over the other. This means that both are expressed and the expressed traits is an intermediate of the individual traits of the alleles.
Answer:If the large seed plant becomes extinct the finches with larger beaks will probably die out thus reducing the finch population
2)This will happen as their source of food is gone and thus leaving them to either feed on what there not used to or die
3)im not too sure of this but this is what i think; In Darwin's finches, those that have short beaks turned out to be an adaptation that made them more suited into poking holes in the ground and feed on grubs. Also the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.
