Length of dna wound onto a histone protein
It is located at the cell sap
Answer:
option A. the factors separate
Explanation:
The Mendel referred alleles as factors. Mendel was unaware about gene but he knew that there are two factors for a single character. The single factor gets transferred from each parent. The gene contains two alleles/factors. The alleles/factors from both mother and father separates at the time of formation of gametes. These gametes from both parents containing alleles/factors recombines and thus forming a zygote.
Thus, factors separate during gamete formation. So, option A is correct.
I found the exercise on the internet. Attached is an image with the terms and the representation of the chromosomes mentioned above.
The term for the position a) would be homologous chromosomes. Position b) is gene locus. Position c) is recessive allele because it is represented by a small letter. Position d) is centromere. Position e) is sister chromatids. Position f) is alleles. Position g) is dominant allele because it is represented by a capital letter.
Answer:
1) The study of heredity is important to determine which traits or characteristics will be passed on from parent to children. It helps us to determine the probability or chance of a disease to occur in children.
2) Yes, we can predict the genotype outcome of an offspring if we have an idea about the genome of the parents. We determine the genotype of the parents and can known about the genotype of the children by constructing a punnet square.
3) The genotype and phenotype are alike by the fact that the genotype will be responsible for developing a particular phenotype. They are different because genotype reflects the genetic makeup of the person. Phenotype reflects the physical characteristics or traits of a person.
