Question

how do Mendel experiment show that traits may be dominant or recessive

Answer 1

Mendel took pea plants with different characteristics – a tall plant and a short plant, produced progeny from them, and calculated the percentages of tall or short progeny. there were no halfway characteristics in this first generation, or F1progeny – no ‘medium-height’ plants. All plants were tall. This meant that only one of the parental traits was seen, not some mixture of the two. He carried his experiment further by getting both the parental plants and these F1 tall plants to reproduce by self-pollination The progeny of the parental plants are, of course, all tall. However, the second-generation, or F2, progeny of the F1 tall plants are not all tall. Instead, one quarter of them are short. This indicates that both the tallness and shortness traits were inherited in the F1 plants, but only the tallness trait, which was dominant, was expressed while shortness, which was recessive trait, remained dormant in F1... hope help

Answer 2

Answer:

Mendel conducted experiment on garden pea plant selecting several visible contrasting character. he selected and cross the pure breed tall pea plant having the genotype TT with pure breed vaar p plant having the genotype. f1 generation consists of only tall plants having the genotype TT.then Mendel self pollinated the F1 generation plants and observed that all plants obtain in f2 generation we are not tall instead one fourth of the two plant where short hands Mandal concluded that happened at plant where are not true breeding they were carrying tips of both short height and tall height the trait autonomous is dominant character while the trait of process is recessive character does mendel's experiments show that traits may be dominant or recessive
