What is the difference between a gene and a allele?

Biology
1 answer:
Lerok [7]3 years ago
5 0

Answer:

A gene is a portion of DNA that determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color.

Explanation:

"Genes come in multiple forms, or versions. Each of these forms is called an allele. For example, the gene responsible for the hair color trait has many alleles: an allele for brown hair, an allele for blonde hair, an allele for red hair, and so on."

Explain the relationship between genotype and phenotype. How can one phenotype result from more than one genotype?
koban [17]

Answer:

<h2>Genotype is the set of genes( allele) of an organism. </h2><h2>Phenotype is the physical expression of the genetic composition of an organism. </h2>

Explanation:

Genotype: 1. It is the genetic composition of an organism, means it is the set of genes( allels) of an organism's DNA, which is responsible for a particular trait of an organism.  

2. Genotypically, an organism can be homozygous(dominant or recessive) or heterozygous.  Some Alleles are dominant over other, means some can  be dominant or other can be recessive.  

3. Genes are responsible for all the traits in an organism, and these traits are inheritable. All the offsprings inherit all traits from their parents.  

Phenotype: 1. Physical expression of the genetic composition of an organism resulted as  phenotype.

2. It  is the physical expression of genes (alleles) which are responsible for any trait.

Please choose the answer. This is a multiple choice.
Rama09 [41]

Answer:

Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.

Explanation:

The basic idea of ​​natural selection is that environmental conditions determine how well the characteristics of organisms contribute to the survival and reproduction of the organism; organisms that do not have these traits may die before reproduction or be less fertile. As long as environmental conditions remain the same or close enough for these traits to remain adaptive, these traits will become more common in populations. The loss of an ecological niche of a species or overcrowding as a result of an increase in abundance can significantly alter the adaptive characteristics required for survival. In this case, and also in any environment where survival is determined more by ecology than secondary sex characteristics, ecological choice takes place.
