Is WW a genotype?
An individual with a (WW) or (Ww) genotype will have a V-shaped peak at the hairline. Only ww individuals will have a straight hairline. To determine the probability of inheritance of a widow’s peak (or any other dominant trait), the genotypes of the parents must be considered.
How do you tell if something is a genotype or phenotype?
The two terms are often used at the same time to describe the same organism, but there is a difference between genotype and phenotype:
- An organism’s genotype is the set of genes in its DNA responsible for a particular trait.
- An organism’s phenotype is the physical expression of those genes.
What phenotype is dd?
Susan’s genotype is “Dd”, so she is considered HETEROZYGOUS (has two different alleles for a specific gene). Although Susan has both the allele “D” to make dimples and the allele “d” in her genotype, her phenotype is the presence of dimples.
|T||Tt (tall)||Tt (tall)|
Which is a phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What is the phenotype of a plant with the genotype WW?
The genotype for the pink flower is RW, and the genotype for the white flower is WW. This would lead to a 50 percent chance of the offspring having a phenotype of pink.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What is my genotype?
In a nutshell: your genotype is your complete heritable genetic identity; the sum total of genes transmitted from parent to offspring. There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells.
