- Hair color.
- Height.
- Sound of your voice.

What is phenotype in your own words?
Phenotype is defined as the physical and psychological characteristics of an organism from both genetics and environment, or a group of organisms having like traits. An example of phenotype is a group of organisms which are all affected in the same ways by nature and nurture. noun.
What is a phenotype simple definition?
Phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.
Is skin color a phenotype?
Skin color variation is one of the most striking examples of human phenotypic diversity. It is dominated by melanin, a pigmentation located in the base of the epidermis and produced by melanocytes. Melanin has two forms, pheomelanin (yellow-reddish) and eumelanin (black-brown).
Is gender a phenotype?
Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male). Phenotypic sex refers to an individual’s sex as determined by their internal and external genitalia, expression of secondary sex characteristics, and behavior.
What is a genotype vs phenotype?
A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.
Is hair color a genotype or phenotype?
A phenotype is your version of a trait. Blue eyes vs brown eyes and curly hair vs straight hair are examples of phenotypes. A genotype is your combination of genes that produce your phenotype. If you have curly hair, your genotype is two curly hair versions of the hair texture gene: one from mom and one from dad.
Is brown hair a phenotype?
Phenotype is the physical appearance eg brown hair.
What comes first genotype or phenotype?
A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including: Epigenetic modifications.
How is a phenotype written?
The genotype is often written as YY or yy, for which each letter represents one of the two alleles in the genotype. Figure 5: Phenotypes are physical expressions of traits that are transmitted by alleles. Capital letters represent dominant alleles and lowercase letters represent recessive alleles.
How do you determine phenotype?
Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.
How are alleles written?
The dominant allele is by convention written with a capital (upper case) letter. Recessive: In the heterozygous genotype, the expression of one allele is sometimes masked by another. The allele which is masked is said to be recessive. The recessive allele is by convention written with a lower case letter.
Which of the following is a phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What are examples of alleles?
Gene vs allele: chart
| Gene | Allele | |
|---|---|---|
| Determines | An organism’s genotype | An organism’s phenotype |
| Number per genus locus | One | Two |
| Various Types | Alleles | Paternal vs maternal Dominant vs recessive |
| Examples | Eye color, hair color, skin pigmentation | Blue eyes, brown hair, dark skin |
Is height an allele?
Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color.
What are alleles in simple words?
Allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.
Is AA genotype or phenotype?
Table 4-5. Correlation of ABO phenotypes and genotypes.
| Phenotype | Possible Genotype |
|---|---|
| A | AA or AO |
| B | BB or BO |
| AB | AB |
| O | OO |
Is blue eyes genotype or phenotype?
Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
Is AA a heterozygous genotype?
Individuals with genotypes AA and aa are homozygotes (i.e., they have two copies of the same allele). Individuals with genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus).
