What phenotypes would be possible round seeds are dominant to wrinkled seeds?
What phenotypes would be possible round seeds are dominant to wrinkled seeds?
Answer and Explanation:
- The round seeds are dominant and wrinkled seeds are recessive.
- Since R is the dominant allele, it will rule over the r allele.
What is the allele for wrinkled seeds?
Again, this is determined by the alleles a plant has at just one genetic locus. In this case, the allele for wrinkled seeds (W) is dominant to the allele for round seeds (w). This means that plants with both genotypes WW and Ww have wrinkled seeds, and only those with genotype ww have round seeds.
Why is the allele for wrinkled seed shape in garden peas considered recessive?
Why is the allele for wrinkled seed shape in garden peas considered recessive? a. It “recedes” in the F2 generation when homozygous parents are crossed. Individuals with the allele have lower fitness than that of individuals with the dominant allele.
Is DD heterozygous or homozygous?
| Individual | Genotype | |
|---|---|---|
| Sam (father) | DD | homozygous dominant |
| Sally (mother) | dd | homozygous recessive |
| Susan (child) | Dd | heterozygous |
What is the probability that an offspring will have round seeds?
In one experiment, Mendel demonstrated that the probability of the event “round seed” occurring was one in the F1 offspring of true-breeding parents, one of which has round seeds and one of which has wrinkled seeds.
Why does a pea plant with the genotype RR have wrinkled seeds?
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.
What genotype is EE?
The person with the Ee genotype is heterozygous for the trait, in this case, free earlobes. An individual is heterozygous for a trait when it has two different allelic forms of a particular gene. The heterozygous individual received one form of the gene from one parent and a different allele from the other parent.
