Question

what do you mean by monohybrid and dihybrid cross and also explain the mendel's experiment ?

why Mendel only used pea plant for experimental ?

what is the difference between F1 generation and F2 generation in a monohybrid cross?​

Answer 1

Answer1:

• A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only. A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.

Mendal's experiment.

• By controlling pollination, Mendel was able to cross pea plants with different forms of traits. In Mendel's first set of experiments, he experimented with just one characteristic at a time. The results of this set of experiments led to Mendel's first law of inheritance called the law of segregation.

$\rm\huge\Blue{AnsWer 2:}$

• For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.

$\rm\huge\Blue{AnsWer 3:}$

The progeny obtained as the result of crossing the plants with contrasting characters is called the first filial generation (F1 ). Whereas the progeny of F1 plants obtained due to self fertilization represents the second filial generation (F2 ).

Answer 2

Answer:

• In a monohybrid cross, the inheritance of a single gene is predicted because the parents are homozygous whereas in a dihybrid cross the parents differ in two different traits.
• For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.
• The term "F1" means the "first filial generation," or the initial cross between two genetically distinct plants. ... An "F2" cross is the next generation, or the result of crossing two sister seedlings from the F1 cross. Selfing an F1 plant produces an F2 also.
