Answer:
XYY, spermatogenesis.
Explanation:
Non disjunction may be defined as the phenomena in which the sister chromatids are unable to separate during the cell division. Non disjunction can occur in both meiosis and mitosis.
The determination of non disjunction is not possible. But the XYY condition in an individual might occur when the homologous chromosomes of Y are unable to separate during the process of spermatogenesis as Y chromosome is present in males only.
Thus, the correct answer is XYY and spermatogenesis
Answer:
A proof for a crime/instance.
Explanation:
Answer:
Addition polymerization is a polymerization process that produces addition polymers. Addition polymers is a polymer that is formed by connecting or addition of the monomer units by a carbon-carbon bond without the use of other chemicals or without co-generation of other products.
It is different then condensation polymerization that co-generates other products or used other reactant chemicals. Polyyethene and polypropene are the examples of addition polymers.
The event is called mutation
A mutation is a rare, accidental or induced modification of genetic information in the genome, specifically DNA.Depending on which part of the genome is affected, the consequences of a mutation may vary.
A mutation is said to be hereditary if the mutated genetic sequence is transmitted to the next generation (see germinal mutations).
It is one of the elements of biodiversity and one of the many factors that may be involved in the evolution of the species (for example: production of new protein which help the bacteria to grow in hostile environment like fungi).
Answer:
Due to the law of independent assortment
Explanation:
In diploid species like humans, all somatic (body) cells have two complete sets of chromosomes, one chromosome inherited from the maternal gamete and one chromosome inherited from the paternal gamete. Each one of the homologous chromosomes contains one copy of each gene, or allele, such that one allele is inherited from each parent. According to the law of independent assortment, maternal and paternal chromosomes are independently assorted during meiosis, which means that different genes localized on different chromosomes are randomly distributed into gametes. In consequence, alleles of different genes are transmitted from parents to offspring independently of one another.
