Male cat has recessive blue eyes and his genotype is ee. What genotype(s) could a female cat have in order
produce kittens that share the father's phenotype? You may construct Punnett squares to support your
nswer.

ee or Ee

Explanation:

If you cross an ee with an ee the only available allele is e so all offspring will be ee. If Ee there is a one in four chance the offspring is ee, as the available combinations are Ee, EE, Ee, and ee. To be recessive in phenotype the kitten must be ee or the allele will be masked by the dominant one.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
