Variations in Dominance

Question 1

What other scientists thought

Answer 1

some traits are still blended such as height, intelligence, skin colour etc. They used Japanese four-o’clock found that Mendel’s laws still worked but Principle of Dominance was not always true.

Question 2

P1 cross, F1 cross

Answer 2

P1 cross has all blended traits. F1 cross has blended traits but trait WW make white, RW make pink, RR make red. There are now three different options. Use lowercase letters as superscripts to show incompletely dominant alleles

Question 3

Co-dominance

Answer 3

With codominance, a cross between organisms with two different phenotypes produces 
offspring with a third phenotype in which both of the parental traits appear together. Parent is A, Parent is B, Child is AB BOTH. Not a mixture. Conventionally, co-dominant alleles are given capital letters with capital letters as superscripts.
