Alleles
What are alleles and what are the two forms?
An allele is a variant form of a gene. ... Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heter...
What is the difference between heterozygous and homozygous alleles?
Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version o...
What is the separation of alleles called?
The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. The segregation of gene variants, called alle...
What are organisms that have 2 different alleles for a particular trait?
An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for ...
Which are sources of new alleles within a population?
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombin...
How many pairs of alleles do chromosomes have?
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a ch...
What type of allele is in all of the sperm nuclei?
How many alleles of every gene are in an egg or sperm?What is dominant and recessive allele?What is recessive allele?Is a gamete the same as allele?H...
What is the separation of alleles?
Segregation is the separation of allele pairs (different traits of the same gene) during meiosis so that they can transfer specifically to separate ga...
How did allales lead to the appearance of different characteristics in offspring?
Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive. The dominance or recessivity associated with a par...
