Chromosomes are made of DNA and protein. DNA is the genetic material that determines the genotype and phenotype of a person. The phenotype is the genes that are expressed and observable.

What is phenotype frequency?
A ratio of individuals with a particular phenotype to the total number of individuals in the population. Individuals with certain phenotype --------------------------------------------------- (Over) Total # of individuals within the population The distribution of traits in a population
What does the nucleus of the sperm cell do?
It carries the chromosomes, which carry the genes, that when combined with the genes carried in the egg, along with environmental factors, determine the phenotype of the offspring.
Which phenotype pairing can the genotypes of the individuals be directly known?
The phenotype pairings which the genotypes of individuals be directly known are homozygous recessive.
What ultimately determines the phenotype of an individual?
Phenotype is what traits are expressed by the organism. So what ever is the dominant Genotype of the organism will determine the Phenotype. For example a dominant R gene will be the Phenotype in RR and Rr. However, if the organism has two recessive rr then the recessive gene will determine the Phenotype.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
Mendel postulated that individuals have elements in pairs that determine a single phenotype What are the paired elements?
gene
Breeding an individual of dominant phenotype with a homozygous recessive individual to determine the individuals genotype?
testcross

phenotype frequency

The phenotype pairings which the genotypes of individuals be directly known are homozygous recessive.
Does phenotype determine genotype?
It is a false statement that "phenotype determines genotype". In fact, it is the opposite. A genotype is the genetics or "instructions" that determine the phenotype. The phenotype is the actual appearance, ex: blue eyes, that is created by a given genotype.
The physical appearance of the entire set of chromosomes of a given animal?
The physical appearance of the entire set of chromosomes of a given animal is a phenotype. A phenotype is a trait that you can observe like the color of a persons eyes.
What are individuals observeable traits called?
Phenotype
What ultimately determines the phenotype of an individual?
Phenotype is what traits are expressed by the organism. So what ever is the dominant Genotype of the organism will determine the Phenotype. For example a dominant R gene will be the Phenotype in RR and Rr. However, if the organism has two recessive rr then the recessive gene will determine the Phenotype.
What is the phenotype for XY?
xy chromosomes mostly fall on male gender.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
