Mendel's Second Law: The Law of Independent Assortment A dihybrid cross is a cross between individuals heterozygous at two different loci. Mendel's second law is also known as the law of independent assortment. The law of independent assortment states that the alleles of one gene sort into gametes independently of the alleles of another gene. To unlock this lesson you must be a Study.com Member.

- A - having the same allele at the same locus on both members of a pair of homologous chromosomes. Homozygous also refers to a genotype consisting of two identical alleles of a gene for a particular trait. An individual may be homozygous dominant (AA) or homozygous recessive (aa).

How do we know which direction heat flows? From cold to hot, or from hot to cold? The definition of Heat is energy transferred due to thermal contact. We know hot things cool down when they touch cold things, and cold things heat up when they touch hot things. So, that means the hot thing has to be losing energy, and the cold thing has to be gaining energy. That means that heat is flowing from hot to cold.

What is the Difference Between Monozygotic and Dizygotic Twins? The main difference between monozygotic and dizygotic twins is that monozygotic twins originate from a single zygote — or fertilized egg — and dizygotic twins come from two zygotes. Monozygotic twins are also called identical twins or maternal twins, and dizygotic twins are also called fraternal twins.Another difference between monozygotic and dizygotic twins is how common they are; about 30 percent of twins are monozygotic, and the other 70 percent are dizygotic.nother difference between monozygotic twins and dizygotic twins is that only monozygotic twins can be conjoined, which means that some parts of their bodies are joined or shared. Many scientists believe that this occurs when the original zygote begins to separate after more than 12 days and is unable to fully divide.

Definitions &Translations Multiples called dizygotic represent multiples from two eggs specifically. For example, a set of triplets may be composed of identical twins from one egg and a third non-identical sibling from a second egg. The most common form of multiple births in humans is twins. Many placental species give birth to multiples as a matter of course, with the resulting group called a litter.

- Heterozygote: An individual who has two different forms of a particular gene, one inherited from each parent. A heterozygote for cystic fibrosis (CF) has the CF gene on one chromosome 7 and the normal paired gene on the other chromosome 7. Also known as carrier. Last Editorial Review: 5/13/2016.

- Fraternal or dizygotic (DZ) twins share only about 50% of their genes. Thus powerful tests of the effects of genes can be made. Twins share many aspects of their environment (e.g., uterine environment, parenting style, education, wealth, culture, community) by virtue of being born in the same time and place.

Gametic Isolation: Definition & Example Gametic isolation is a type of prezygotic barrier. Gametic isolation happens when the egg and sperm are released but a zygote is not formed. A zygote is the cell produced when an egg and sperm unite. The term ' gamete ' refers to the reproductive cells like eggs and sperm.
