What is the genotype of a trait for which the two alleles an individual carries differ from each other? What is the difference between genes and alleles in biology? Describe how selection for a dominant and a recessive allele will differ from one another. What is the difference between dominan...

We refer to two genes as alleles of each other when they are inherited as alternatives to each other. In molecular terms, alleles are different forms of the same gene. There can be more than two alleles of a gene in a population of organisms. But any given organism has only two alleles...
How are alleles and traits related? How are genes and alleles related to genotype and phenotype? How do multiple allele traits differ from polygenic traits? How are polygenic and multifactorial traits different? Explain how genes are expressed for a particular trait. What are the differences between...
We refer to two genes as alleles of each other when they are inherited as alternatives to each other. In molecular terms, alleles are different forms of the same gene. There can be more than two alleles of a gene in a population of organisms. But any given organism has only two alleles...
The interaction of genes that are not alleles, in particular the suppression of the effect of one such gene by another, which is used to order gene functions into pathways. Muller’s ratchet A theory predicting that small asexual populations invariably accumulate deleterious mutation loads as a co...
Alleles are alternative versions of the same gene. Image by: vitstudio, Shutterstock Marker A sequence of DNA that has a determined location on the chromosome. They are landmarks used to track inheritance. Autosomal-Recessive This term refers to inherited conditions. Recessive conditions are those...
Drosophila Melanogaster first became an interest in the early 1900s when Thomas Hunt Morgan began his research on the fly’s sex inheritance and came to the conclusion that our genes are carried in our chromosomes which gives us our phenotypes. Morgan like many other scientists chose to experimen...
What is the genotype of a trait for which the two alleles an individual carries differ from each other? What is the difference between gene and genotype? Define allele, gene, dominant, and recessive as they relate to patterns of inheritance. How are sex-linked genes passed? How do we know...
