Wrinkled seeds are recessive.
Is smooth dominant?
In a plant, smooth seeds (s) are dominant over wrinkled seeds (s) and green seeds (G) are dominant over orange seeds (g). A plant homozygous for smooth and green seeds is crossed with a plant having wrinkled and orange seeds.
Which pea is dominant?
The yellow color is dominant over green color. For pod color, there are two traits – green and yellow. Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted.
Which pea trait is recessive?
Because the allele that produces wrinkled peas is recessive, the offspring of this cross will all have wrinkled peas. Mendel then explains the concept of dominant and recessive alleles by saying, “By performing my experiments with peas, I learned a lot about genetics and how traits are passed on.
Are round peas dominant or recessive?
Round pea (R) is dominant to wrinkled pea (r). The r gene is on chromosome 5.
Which genes are recessive?
A recessive gene is a gene whose effects are masked in the presence of a dominant gene. Every organism that has DNA packed into chromosomes has two alleles, or forms of a gene, for each gene: one inherited from their mother, and one inherited from their father.
Which of the following is not a dominant character of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
Which of the following is dominant?
1 Answer. Green coloured pod and rounded seed is dominant character according to Mendel.
Which of the following is dominant character?
Therefore, according to the Mendel experiment green colored pod and rounded seed is a dominant character. So, option D) is the correct option.
Why are green peas recessive?
Mendel’s gene involved in pea color decides whether the chlorophyll in the pea will be broken down and 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.
Which is a dominant trait that Mendel observed in pea plants?
These plants would serve as the P1 generation for the experiment. In this case, Mendel crossed the plants with wrinkled and yellow seeds (rrYY) with plants with round, green seeds (RRyy). From his earlier monohybrid crosses, Mendel knew which traits were dominant: round and yellow.
Is hybrid dominant or recessive?
A hybrid is called heterozygous, as it has two different alleles. The offspring from a pure tall pea plant, cross-pollinated with a pure short pea plant, will result in a heterozygous plant for tallness. No organism has all dominant or all recessive genes.
| Dominant | Recessive |
|---|---|
| Widow’s peak hairline | Straight hairline |
What is a homozygous dominant trait?
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. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.
What is the dominant seed color in a pea plant?
yellow
For the seed colour, yellow is the dominant trait and green is recessive while for the fruit (pod) colour, green is dominant and yellow is recessive.
Why is round dominant to wrinkled?
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.
Which of the peas traits yellow or green is dominant explain your answer?
Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive. When true-breeding plants were cross-fertilized, in which one parent had yellow seeds and one had green seeds, all of the F1 hybrid offspring had yellow seeds.
Is dark skin dominant or recessive?
Each gene has two forms: dark skin allele (A, B, and C) and light skin allele (a, b, and c). Neither allele is completely dominant to the other, and heterozygotes exhibit an intermediate phenotype (incomplete dominance). Each dark skin allele in the genotype adds pigment by increasing melanin production.
What genes are inherited from father only?
#2 Y-Linked Traits (for Sons)
Sons can only inherit a Y chromosome from dad, which means all traits that are only found on the Y chromosome come from dad, not mom. Background: All men inherit a Y chromosome from their father, and all fathers pass down a Y chromosome to their sons.
How do you tell if a trait is dominant or recessive?
If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous.
Which character has not been selected by Mendel in pea plants?
Mendel chose Pisum sativum (pea plant) for his experiments. He selected seven traits of pea plant. It excludes plant colour. He chose characters like flower colour, flower position, stem length, seed shape, seed colour, pod shape and pod colour.
Which of the following is true of dominant genes?
Answer and Explanation: The correct answer is b. It will always be expressed in a person who has the trait.
