What is the homogamy theory?
The theory of homogamy states that in their potential or actual partners individuals prefer characteristics that are similar to themselves (“birds of a feather flock together”).
What are examples of heterozygote advantage?
Sickle cell anemia is the best-known example of heterozygote advantage and balanced polymorphism in humans.
Can you undo inbreeding?
You can’t reverse it in a given individual, at least not with any technology we currently have, but you can entirely reverse it in the next generation if the inbred individual mates with an unrelated individual, this immediately reduces the level of inbreeding in the offspring to the same level of any other non …
Why is heterozygosity important?
The result of our analysis suggests that more heterozygous individuals have a higher longevity and may be an important source of genetic variability of a population, likely contributing to a stabilization of the effective population size.
What is a Homogamous relationship?
Homogamy is marriage between individuals who are, in some culturally important way, similar to each other. It is a form of assortative mating. The union may be based on socioeconomic status, class, gender, caste, ethnicity, or religion, or age in the case of the so-called age homogamy.
What is heterozygous example?
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
Can human siblings mate?
Inbreeding occurs when two closely related organisms mate with each other and produce offspring. The two main negative consequences of inbreeding are an increased risk of undesirable genes and a reduction in genetic diversity. The House of Habsburg may be the best example of the effects of inbreeding in humans.
Are blue eyes caused by inbreeding?
However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes. This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you.
What is underdominance and overdominance?
In genetics, underdominance (referred to in some texts as ” negative overdominance “) is the opposite of overdominance. It is the selection against the heterozygote, causing disruptive selection and divergent genotypes.
What does it mean to possess an Undefiled marriage bed?
Answer: The scripture you are referring to in regard to what it means to possess an undefiled marriage bed (assuming, of course, that the couple is a man and a woman, and not the unbiblical coupling of two men or two women) between a couple is found in Hebrews 13.
What do you mean by marriage?

What happens when we depart from the Bible on marriage?
If we depart from, or fail to stand up for, the biblical view of marriage, we are taking a step away from the gospel itself. The whole Bible is the story of the marital love of God, as I demonstrate in this book .
