What were the observations made by Mendel after obtaining results of
monohybrid cross in pea plants (height as a trait)
Answers
Answer:
in f1 gen he saw that all plants were tall phenotypically but genotypically they were heterzygous ,the dominant trait masked the recessive short height
but in f2 the short plants reappeared which helped mendel derive law of segregation later

Answer:
A monohybrid cross is the hybrid of two individuals with homozygous genotypes which result in the opposite phenotype for a certain genetic trait.”
“The cross between two monohybrid traits (TT and tt) is called a Monohybrid Cross.”
Monohybrid cross is responsible for the inheritance of one gene. It can be easily shown through a Punnett Square.
Monohybrid cross is used by geneticists to observe how homozygous offspring express heterozygous genotypes inherited from their parents.
How To Carry Out A Monohybrid Cross?
The ratios of the phenotype and the genotype that are estimated are only probabilities. Listed below are steps that can be used to calculate a monohybrid cross:
Indicate the alleles using characters – recessive alleles can be indicated by lower case letters while dominant alleles can be indicated by upper case letters
Note down both the phenotype and the genotype of the parents or the parental generation that are being crossed
Jot down the genotype of the gametes from the parental generation – As a result of meiotic division, the gametes will be haploid
Tabulate a Punnett square to chalk out the probable combinations of the gametes – Any combination is possible as the process of fertilization is random
The phenotype and the genotype ratios of the prospective offspring can be written. The outcome hence obtained is known as the F1 generation. The F2, F3 etc generations form the subsequent generations.
