Are wrinkled seeds a recessive trait?

Having wrinkled seeds is a recessive trait. What do you know about the offspring of two plants with wrinkled seeds? ~two plants with wrinkled seeds must have a genotype with two recessive alleles. Therefore, the parents will only be able to pass recessive (wrinkled seeds) on to their offspring.

Why was green considered to be the recessive trait for peas?

Mendel’s gene involved in pea color decides whether the chlorophyll in the pea will be broken down or degraded. When this gene isn’t working, the chlorophyll stays around and the pea is green. So in this case the recessive trait is indeed due to a broken gene.

What does it mean when alleles are recessive?

Recessive refers to a type of allele which will not be manifested in an individual unless both of the individual’s copies of that gene have that particular genotype.

Which allele is recessive for seed color?

green-seed allele
Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive.

Which of the following is recessive trait in pea plant?

Explanation: Green seed andwrinkled seeds were recessive to yellow and round seeds; yellow, constricted pods were recessive to green and full pods. Dwarf stem and white flowers wererecessive to tall stem and violet flowers. Thus, the correct answer is option b.

What is the recessive color of a pea plant’s seed coat?

Genetics Quiz

Are wrinkled peas dominant or recessive?

Because the allele that produces wrinkled peas is recessive, the offspring of this cross will all have wrinkled peas.

Is wrinkled seed shape dominant or recessive?

In pea plant, round seed is a dominant trait while wrinkled seed is a recessive trait. Here, ‘R’ is the dominant allele and ‘r’ is the recessive allele for the seed shape of the pea plant. The plant with round seeds would have genotype RR. Then, the plant with genotype rr would have wrinkled seeds.

How is a recessive allele different from a dominant allele?

A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.

What is recessive and dominant allele?

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Which pair of alleles represents a recessive trait?

Recessive alleles are denoted by a lowercase letter (a versus A). 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.

Which is dominant allele A or B?

With eye color, for instance, “B” stands for a brown allele and “b” stands for a blue allele. An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.
