Question
Gregor Mendel studied garden pea plants because
Mendel examined 7 characteristics in pea plants; one of the them was flower color. When purple and white flowers were crossed, the F1 generation of flowers were always
If the F1 flowers were mated with each other (F1 x F1), then the F2 generation flowers would be
After studying his pea plant experimental results, Mendel concluded that parents transmit
A genetic cross results in a 9:3:3:1 phenotypic ratio. This genetic cross is
Human height shows lots of variation from very tall to very short. This is most likely controlled by
In the human ABO blood typing, the blood types are type A, type B, type AB and type O. The blood proteins A and B are
What finding determined that genes were carried on chromosomes?
Nondisjunction
If parents are concerned about the risks of genetic problems manifesting in their potential children,
all of the above.Explanation / Answer
please ask questions separtely and not all at once
1) all of the above
2)all of the plants in the F1 generation had purple flowers. Since purple is dominant over white and all of the F1 individuals were heterozygous, the phennotype purple was expressed.
3)3/4 purple, 1/4 white.
Pw x Pw will give PP, Pw, Pw, ww. Three of these are phenotypically purple and one is white and hence the ratio is 3:1
4)some 'factor' about traits to their offspring that may or may not be expressed.. As we saw in the above examples recessive traits can be masked if present with dominant ones
