help on one question i don't get (biology)?
What information must you know to determine the phenotypes of different genotypes for a gene with two alleles?
can someone give me a short and sweet answer yet giving all the information needed?

If you know the dominant/recessive alleles for the gene, and the genotypes of the two species then follow this logic:
If X (capitalized) is the dominant allele, and x is the recessive allele, then list the possible combinations:
XX, Xx, xX, and xx
XX, Xx, and xX will have the dominant phenotype (since one dominant + one recessive will always equal a dominant phenotype) whereas xx is the only genotype that will have the recessive phenotype.
Well.........you need t know the trait or characteristics.Among them which is dominant and which is recessive.
which characteristic is dominant..?
