Complete answer: Green cotyledon colour was one of the recessive traits studied by Mendel in
Which character is recessive in pea plant?
Explanation: Mendel based his experiments on pea plants and studied seven pairs of contrasting traits. Yellow seed colour is the dominant trait and green seed colour is the recessive trait.
Which of the following is a recessive character of Mendel?
So, the correct answer is ‘Wrinkled seed‘.
Which one of the following is not a recessive character of a pea plant *?
Mendel worked on garden pea and choose seven characters for this. Green seed colour is the recessive character in his experiment and the dominant character for seed colour is yellow. Axial flower position, green pod colour and round seed shape are all dominant characters.
Which of the following is the example of recessive traits?
Examples of Recessive Traits
Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits. Having round (as opposed to almond-shaped) eyes is recessive, along with inability to roll one’s tongue.
How do Mendel’s experiments show that gene may be dominant or recessive?
Mendel selected true breeding tall (TT) and dwarf (tt) pea plants. When a tall pea plant is crossed with a short (dwarf) pea plant, all the F1 hybrids are tall. (i.e., in this case, the gene causing tallness is dominant while the gene causing dwarfness is recessive.).
Which of the following is a dominant trait in pea plant?
So, the correct answer is ‘green pod‘.
Which of the following is a characteristic studied by Mendel in pea plant?
Mendel chose seven pairs of contrasting traits, namely plant height, flower position, pod colour, pod shape, seed colour, seed shape and flower colour.
Which of the following is recessive trait in pea plant Mcq?
1. Which of the following is a recessive trait in pea plants? Clarification: Recessive traits are the ones that require both alleles to be present to result in the expression of the gene product. Of the mentioned traits, only dwarf stem height is a recessive trait.
Which of the following is a type of autosomal recessive genetic disorder Mcq?
Cystic fibrosis is an autosomal recessive genetic disorder.
What is a recessive character?
Refers to a trait that is expressed only when genotype is homozygous; a trait that tends to be masked by other inherited traits, yet persists in a population among heterozygous genotypes.
Which of the following is an example of recessive genotype?
Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait. One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin.
How do Mendel’s experiments show that traits may be dominant or recessive Class 10 short answer?
Mendel’s experiments show that the Traits may be dominant or recessive by performing a monohybrid cross. Monohybrid cross between two pure breeding varieties always obtained hybrid progeny exhibiting one parental trait while the opposite trait was never expressed in the F1 generation.
What are dominant traits and recessive traits?
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. If one of the alleles is dominant, then the associated characteristic is less likely to manifest.
How do Mendel’s experiments show that the i traits may be dominant or recessive II traits are inherited independently?
In this experiment Mendel concluded that the F1 tall plants were not true-breeding, they were carrying both short and tall height traits. They appeared tall only because the tall traits were dominant over the dwarf trait. This shows that traits may be dominant or recessive.
Why is a trait recessive?
In the case of a recessive trait, the alleles of the trait-causing gene are the same, and both (recessive) alleles must be present to express the trait. A recessive allele does not produce a trait at all when only one copy is present.
Why did Mendel choose Pisum sativum?
Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
What 7 traits did Mendel study in pea plants?
The characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position.
What is the recessive color of a pea plant’s seed coat?
green
Mendel’s experiments showed that green is the recessive seed color in pea plants.
Are short stems dominant or recessive?
Short stems are dominant over long stems.
Which of the following traits are recessive in pea plant Dwarfness violet flower wrinkled seed?
Solution : Dwarfness and wrinkled seeds are the recessive characters.
