What is the phenotype of a homozygous dominant?
What is the phenotype of a pea plant that is homozygous dominant ( TT ) for the tall trait? Tall. What is the phenotype of a pea plant that is heterozygous ( Tt )? It is also tall….
| Genotype | Definition | Example |
|---|---|---|
| Homozygous dominant | Two dominant alleles | TT |
| Homozygous recessive | Two recessive alleles | tt |
What is the phenotype of a pea plant that is homozygous dominant for purple flowers?
In pea plants, purebred purple flowers have a genotype with two purple alleles, which produces a phenotype of purple petals. Purebred white flowers have a genotype of two white alleles, which displays the white phenotype.
What would be the phenotype of a cross between a homozygous dominant tall plant and a homozygous recessive short plant?
25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.
What is an example of a homozygous phenotype?
Homozygous examples You can have brown eyes whether you’re homozygous (two alleles for brown eyes) or heterozygous (one for brown and one for blue). This is unlike the allele for blue eyes, which is recessive. You need two identical blue eye alleles in order to have blue eyes.
What is a homozygous dominant?
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 are dominant phenotypes?
Organisms that reproduce sexually carry genes from each parent. The genes that are expressed are responsible for your traits, or phenotype. A dominant phenotype is a trait resulting from a dominant gene.
What would be the phenotype of a homozygous recessive YY pea plant?
YY is the homozygous dominant genotype (2 Y alleles). The phenotype of this genotype is yellow seed color. Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is green seed color.
What would be the phenotype of a cross between a homozygous?
Related Genotype(s) Thus, if one parent is homozygous for type A blood and the other is homozygous for type B, the offspring will have a new phenotype, type AB.
What is the phenotype of a heterozygote?
Heterozygous individuals have a phenotype somewhere in the middle, what people might call “wavy” hair. In a heterozygous individual, only one curly allele is present, and only half the amount of protein can be made. This causes the hair to be about as half as curly as in a homozygous curly individual.
What is the phenotype of a heterozygous red flower?
The red color is dominant as the red flower is heterozygous. The white color is homozygous.
Which is the dominant color of pea pods?
In pea plants, yellow pod color is recessive and green pod color is dominant. A heterozygous plant produced offspring with a plant that is homozygous dominant for the trait. What is the dominant shape of a pea pod and why? The dominant shape of a pea pod is smooth.
What is the phenotypic ratio of a plant with terminal flowers?
(iii) Phenotypic ratio for the above cross – 3 : 1 (3 pea plants with axial flowers : 1 pea plant with terminal flowers) Genotypic ratio for the above cross – 1 : 2 : 1 (1 homozygous plant with axial flowers : 2 heterozygous plants with axial flowers : 1 homozygous plant with terminal flowers)
What is the phenotype of F1 generation plants?
(i) The phenotype of the F1 generation in plants with axial flowers will be produced. The genotype of F1 generation plants is Aa.
Which is true of Mendel’s law of dominance?
(iv) Mendel’s Law of Dominance : Of a pair of contrasting characters present together, only one can express itself, while the other remains suppressed. The one which is expressed is the dominant and the one which is not expressed is the recessive. Is there an error in this question or solution?
