Question

Gregor Mendel is described as the father of genetics. He studied the inheritance patterns of pea plants differing in one or two traits. The following is one such experiment. He crossed pure breeding plants for smooth, yellow seeds with pure breeding plants for green, wrinkled seeds to produce an F1 generation. All seeds of F1 had smooth, yellow seeds. The F1 plants were self-fertilised and produced the following results:
315 smooth yellow
108 smooth green
101 wrinkled yellow
32 wrinkled green
a) What type of inheritance patterns was Mendel studying in the cross above?

Answer 1

b) state the phenotypic ratio obtained in the F1 cross.
c. Mendel went through his data and examined each characteristic separately. He compared the total numbers of round versus wrinkled and yellow versus green seeds, as shown in the tables below. Copy and complete the tables:

d) Using the results of the phenotypic ratios obtained in c), state one conclusion which can be made.
e) Do you expect all crosses which involve two traits to yield the same phenotypic ratio as in b)? Explain your answer.

PLEASE HELP. Just this one, actually. I don't understand the table that much.
Thank you !

Answer 2

Mendel was trying to crack how traits (allele is now the term we use) are inherited from Parent to offspring. He was looking for a pattern.
create a ratio between the phenotype (physical characteristics) smooth and wrinkled
then green and yellow

Answer 3

In his data, the 1st Filial (F1) generation, revealed that dominant traits are about 75% and recessive about 25%. Then he crossed bred again to obtain 2nd Filial (F2) and data showed a ratio of dominant to recessive with 3:1

Answer 4

with regards to your data and table, make sure you fill out the corresponding item that matches the description
