Coat color in rabbits is expressed with four different phenotypes by a single gene. - This is an example of multiple alleles. The trait of coat color is determine by one gene, but 4 different variants in that gene produce 4 different phenotypes.
When a certain variety of black chicken is crossed with a white chicken, all of the offspring are checkered. Black and white feathers are produced in the offspring. This is an example of codominance - When black and white chickens are crossed, they produce heterozygous chickens that are checkered. This heterozygous phenotype results in the expression of both traits, as both are expressed in the phenotype (checkered). Then, when the heterozygotes are crossed, the homozygous black and white chickens and be produced again. If it was incomplete dominance, we would expect the rabbits to be grey.
The F1 generation produced by a cross between red-flowered (RR) and white-flowered (r) Four o'clock plants consists of pink colored flowers - this is an example of incomplete dominance, which is characterised by a blending phenotype, where one allele is not fully dominant over the other. If it was codominance, we would expect stripes or spots of both red and white.
The distribution of plant heights forms a bell-shaped curve with intermediate heights occurring most often. - this is an example of polygenic traits. Height is usually not controlled just by one gene, instead it is the result of the action of several different genes that have small effects on the phenotype.
Leaves on a tree can have different sizes and shapes depending on the amount of light they receive. This is an example of environmental influence on gene expression - the light is an environmental factor that influences what and how genes are transcribed, producing effects on leaf shape.
Genetic disorders in human mitochondrial DNA follow non. Mendelian patterns of inheritance - this is an example of maternal inheritance. Mitochondrial DNA is only inherited from the mother, this is because during fertilization, the egg cell is so much larger than the sperm cell and contains so many more mitochondria (around 100,000x more). And this is the source of where all the mitochondria arise.
