Crossing-over
The creation of new combinations of alleles is called genetic recombination. This process occurs during meiosis when homologous chromosomes exchange genetic material, leading to the formation of unique combinations of alleles in offspring.
new combinations of alleles
Crest in pigeons is determined by specific alleles that influence the expression of certain proteins involved in feather development. When a pigeon inherits the "crest" alleles from its parents, these alleles activate pathways that produce proteins promoting the growth and formation of the crest feathers. The interaction between these alleles and proteins ultimately results in the distinctive crest phenotype observed in some pigeon breeds. Thus, the combination of genetic information and protein expression is crucial for crest formation.
The physical result of a combination of alleles is known as the phenotype, which refers to the physical characteristics or traits of an organism. Different combinations of alleles can lead to variations in the phenotype, such as eye color, height, or hair texture.
mutation
Mendel's Law of Segregation states that each individual has two alleles for a particular trait, and these alleles separate during gamete formation so that each gamete receives only one allele. This results in the random distribution of alleles into gametes and leads to genetic variation in offspring.
