What did Mendel see in his F2 generation?
The F2 generation results from self-pollination of F1 plants, and contained 75% purple flowers and 25% white flowers. This type of experiment is known as a monohybrid cross.
What was displayed in the F1 generation of Mendel’s experiments?
Dominant and recessive traits Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked.
What does F1 generation 10 mean?
F1 or first filial generation is the generation of hybrids produced from a cross between the genetically different individuals called parents. F2 second filial generation is the generation of individuals which arises as a result of inbreeding of interbreeding amongst individuals of F1 generation.
What did Mendel say about three possible combinations of genes?
Mendel theorized that genes could be formed up by three possible combinations of heredity units that are said to be factors: AA, aa, Aa. The big A shows dominant factor and small a shows recessive factor. The beginning plants were homozygous AA or aa, F1 generation was Aa and F2 generation was AA, aa or Aa.
What does Mendel mean by dominant and recessive traits?
Upon compiling his results for many thousands of plants, Mendel concluded that the characteristics could be divided into expressed and latent traits. He called these dominant and recessive traits, respectively. Dominant traits are those that are inherited unchanged in a hybridization.
How did Gregor Mendel study patterns of inheritance?
Gregor Mendel performed breeding experiments in his garden to analyzing patterns of inheritance. He opted cross-bred normal pea plants with selective traits over various generations.
What are the traits of Mendel’s pea plant?
The total of four traits that Mendel chose from the pea plant for crossbreeding were homozygous and dominant for round (RR) yellow (YY) seeds and homozygous and recessive for wrinkled (rr) green (yy) seeds. These were taken as the parent generation (P) When they have crossed the first generation (F1) of plants were all heterozygous.
