explain how meiosis ensures genetic variation among offspring and perpetuation of parental traits.
Homework Answers
Meiosis has meiosis I and meiosis II. In meiosis I, there is genetic recombination, while in meiosis II there is just replication like mitosis. Meiosis ensures genetic recombination by crossing over between the maternal and paternal chromosomes, such that the daughter chromosome is not identical to either of the parents. On the other side, crossing over may happen in a region of chromosome, where there is no difference between the two parents, resulting in no recombination and perpetuation of the parental traits.

Processes that determine heredity and contribute to genetic variation Meiosis guarantees that in a sexual life cycle, offspring will inherit one complete set of chromosomes (and their associated genes and traits) from each parent. The transmission of traits from parents to offspring is called heredity. Another important aspect of meiosis and the sexual life cycle is the role these processes play in contributing to genetic variation. Although offspring always resemble their parents, they are genetically different from both of their...

1. While the traits studied in Exercise 1 were hypothetical genetic traits, what type of genetic traits do you think are important to study and predict? Give an example of a genetic trait that is carefully monitored when two parents are creating an offspring and why it would be important to monitor. 2. Describe a karyotype and explain how it is performed. 3. Would a normal karyotype mean that a person would not have any disorder or disease in their...

How do epigenetic traits differ from traditional genetic traits, such as the differences in color and shape of peas that Mendel studied? A) Phenotype is stably inherited by offspring. B) Phenotype is not transmitted to offspring. C) New phenotype involves changes to the DNA sequence. D) New phenotype is caused by modifications to chromatin. E) Phenotype can be influenced by environmental factors.
