What is most likely to cause no difference in phenotype between two individuals?
There are many things that will cause no difference in phenotype between two individuals. One of these things is the water they drink.
How many dominant alleles must be present in order to show the dominant phenotype?
I'm not sure...
Compare and contrast genotype and phenotype?
An organism's genotype is its genetic identity. The genotype is comprised of all the genetic material inherited from both parents. The genotype is what "tells" each individual cell how to function. The phenotype is the physical expression of an organism's genotype. For example, if a person's genotype for eye color is one dominant allele for brown and one recessive for blue, then the individual's phenotype would be their actual eye color which in this case would be brown.
What is a phenotypic ratio?
A ratio that shows the different outcomes you can get from a genetic cross.A ratio that shows the varied outcomes that results from a genetic cross and is based on physical appearance alone. For example yellow flowers, round seeds, brown hair, green eyes etc.The genetic make up of an organism is called genotype and the external appearance or expression of the genetic make up is called phenotype (Color, height, shape etc.). The ratio indicates the number of heterozygotes and homozygotes with reference to the genotypic ratio and to the number of phenotypes expressed as phenotypic ratio. The concept was given by Sir Gregor Johann Mendel, Father of Genetics who worked on pea plant with reference to 7 different characters. The result obtained for a cross between a single character is called monohybrid cross and the ratio is referred to as monohybrid ratio which is 1:2:1 for genotypic ratio and 3:1 for phenotypic ratio.in the dihybrid cross for the phenotypic ratio it is 9:3:3:1.
Define and distinguish between pleiotropy and polygenic inheritance?
Pleiotropy: one gene affects many traits (phenotypes) Polygenic: many genes affect one trait (phenotype)
How many pages does The Extended Phenotype have?
The Extended Phenotype has 307 pages.
The many varieties of dogs today are the result of what type of breeding?
Cross Breeding
How can you tell someone pheynotype?
There are many ways to tell someone about their phenotype. You could describe their features as this is what a phenotype is.
How do you make a single-factor cross?
1. Assign symbols (letters) 2. Indicate genotype of parents 3. How many different gametes 4. Punnet square 5. Determine phenotype
What an organism looks like as a result of its genes?
For the sake of simplicity the discussion here will be of mendellian genetics. The way an animal looks (phenotype) may only represent a portion of it's genotype since dominant traits mask the expression of recessive ones. Behavior is not explained by genetics in many cases...the more complex the organism the more likely behavioral nuance is affected by elements beyond genetics.
How many alleles influence a phenotype in complete dominance?
8

How many recessive alleles are needed to show up in the phenotype?
Two (together).
Why are there different breeds of oranges?
The different breeds of oranges are a result of many subspecies and cross breeding. These all have their own unique look, taste, and texture.
