Whenever a pea plant with homozygous dominant trait for a character is cross-fertilized with the plant having contrasting recessive trait, we observe:

• A

  all the ${\mathrm{F}}_1$progeny showing only the recessive trait

• B

  all the ${\mathrm{F}}_1$progeny showing intermediate trait

• C

  all the ${\mathrm{F}}_1$progeny showing only the dominant trait 

• D

  all the ${\mathrm{F}}_1$progeny showing the traits of both parents.
