Question

A Mendelian experiment consisted of breeding pea plant bearing violet flower with pea plant bearing white flower. What is the result of F1 progeny?

Answer 1

Hint: Mendelian crosses is the tool described by the scientist GREGOR MENDEL and it’s a cross to determine the unknown traits. Mendel gave different types of crosses such as test cross, back cross, dihybrid and monohybrid cross to study the traits in pea plants. Mendelian cross describes the two categories of genes responsible for the trait of the individual– Dominant and recessive genes.

Complete step by step answer: Test cross: - It’s a cross between individual with dominant phenotype but unknown genotype (VV or Vv) and an organism with homozygous recessive genotype (vv).
Now we will study how this cross occurs:
Simply F1 x recessive genotype. The common example of a test cross is producing violet flowers in F1 progeny.
According to this definition there are two possibilities to producing traits in F1 progeny.
The cross between VV ( homozygous violet genotype) x vv (homozygous white recessive genotype)
 F1 progeny – Vv (violet flower) (Hybrid)
The cross between Vv (heterozygous violet genotype) x vv (homozygous white recessive genotype)
 F1 progeny – Vv (violet flower) or vv (white flower hybrid) with 2:2
According to this theory of Mendel’s, after cross the result of F1 progeny produces maximum violet flowers.

Note: Mendel is known as the father of genetics, he gave the first law known as law of segregation, second law known as law of independent assortment, law of dominance and law of paired factors. He studied pea plants because its traits are easy to study and its plant is available annually.
