Alleles in the F1 must be Tt to have height variety in the F2.
Answer:
Besides storing genetic information, nucleic acids helps in
Understanding diseases
Creation of proteins
Transmission of information
Explanation:
Understanding diseases
Knowledge about the nucleic acids and their mechanism of action helps in understanding the causes of a disease and the possible cure for the disease. A genetic disease is caused when there is a faulty gene, which is made up of nucleic acids, is present in the genome. These genes will make faulty RNA's which will result in the establishment of faulty proteins. Hence, by having understanding about nucleic acids, diseases can be studies and cured.
Creation of proteins
The information from the DNA is coded by the mRNA which is used to make proteins.
Transmission of information
Apart from storing information, the nucleic acids such as the DNA are also involved in the transmission of information.
The answer is 3:1.
If we imagine that plant has two alleles for the
trait, we can dominant allele represent with P represents and recessive allele with p. To get purebred monohybrid in the first generation, parents must be a dominant homozygote (PP) and a recessive hetero<span>zygote (pp):
Parental generation: PP x pp
The first generation: Pp Pp Pp Pp
Pp represents a heterozygote.
If we cross these heterozygotes:
The first generation: Pp x Pp
The second generation: PP Pp Pp pp
If dominant allele determines the phenotype, there will be 3 plants (one PP and two Pp) with one phenotype and only 1 plant </span><span>(pp)</span> with another phenotype and vice versa.
