In a cross between a red flower and a white flower,the offspring have red flowers in the majority,while white flowers are much less frequent. In this cross,the red colour character is:

How many true-breeding pea plant varieties did Mendel select as pairs,which were similar except in one character with contrasting traits?

In his experiments,Mendel observed wrinkled peas. These wrinkles are caused by the accumulation of sugar instead of starch. This is due to the deficiency of which enzyme?

Which scientist did not contribute to the rediscovery of Mendel's results?

In a monohybrid cross of plants with red and white flowered plants,Mendel got only red flowered plants. On self-pollinating these $F_1$ plants,he got both red and white flowered plants in a $3:1$ ratio. Explain the basis of using $RR$ and $rr$ symbols to represent the genotype of plants of the parental generation.

Which scientist worked on garden peas before Mendel?
