Answer:
Part A: Pp
Part B: 1/3
Explanation:
A: The purple flower color is regulated by dominant allele "P". Since self-fertilization of the purple-flowered plant with unknown genotype gives both purple and white-flowered progeny in almost 3:1 ratio, the parent plant was heterozygous dominant for the trait. Its genotype is "Pp".
Segregation of recessive and dominant alleles during gamete formation leads to the production of two types of gametes with either "P" or "p" alleles. The random fusion of these gametes produces progeny in following phenotype ratio= 3 purple: 1 white.
B. Out of the 3 purple-flowered progeny, 1 is homozygous dominant (PP). Therefore, the probability of the purple-flowered progeny to breed true is 1/3.
Answer:
DNA starts off on the nucleus where it then gets separated into DRNA so that it can travel to other parts of the cell. It is the. Carried by vehicle to the rough ER where ribosomes are added to it then it goes to the smooth ER where waste is expelled. Finally, it goes to the Golgi apparatus where it is either stored or carried to a part of the cell.
Explanation:
Natural Selection lets them survive.
By using different types of technology, like weather satellites, radar, and river gauges, scientists can reduce flood damage and loss of life by providing Advance warnings
Answer:
The correct answer is "#2 and #3 only"
Explanation:
A and a are alleles, and R and r are alleles. Alleles of a gene are found at the same locus on homologous chromosomes. Every pair of the alleles depicts the genotype of a particular gene. Homozygous genotype occurs when two similar alleles at same locus and heterozygous in case of two nonidentical alleles. Due to the alleles there occurs a change in the appearance. An alleles create differences in gene.
