D.
A fixed allele is homozygous within a population so D should be the correct answer.
Hope this helps!
Answer:
a) The genes present on separate chromosomes exhibit indepedent assortment.
b) The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
Explanation:
a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.
b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.
The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
A. Phenotype.
Genotype is the genetic constitution of an individual organism, genetic makeup is part of the DNA sequence, and personality is the way a person acts.
Arteries always flow away from the heart versus veins which carry blood to the heart. Bronchi are part of the lungs and move air. Platelets are components of blood that are responsible for clotting the blood.
Answer:
The correct option is<em> D) Models are not the "real thing" so it will never correctly represent the system in all respects.</em>
Explanation:
Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.
As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.
