1) a particular variety of corn has a gene for kernel color and a gene for height with the following phenotypes:
CC,Cc: purple kernel
cc: white kernel
T_1_T_1_: tall stem
T_1_T_2_: medium height stem
T_2_T_2_: dwarf stem
Give the proportions of geneotypes and phenotypes produced if a dihybrid plant is selfed.
2) conduct a chi square for this:
Two agouti mice are crossed, and over a period of a year they produce 48 offspring with the following phenotypes:
28 agouti mice
7 black mice
13 albino mice
what is your hypothesis about the genetic control of coat color in these mice? do the data support that hypothesis?
3) In a paternity dispute, a type AB woman claimed that one of four men, each with different blood type was the father of her type A child. which of the following could be the blood type of the father of the child on the basis of the evidence given?
