Could you be more specific? I can't really answer the question when it's written like that (no offense).
The right answer is 1/4.
Two carriers of the disease each have a chance in two to transmit their sick gene ie: 1/2 * 1/2 = 1/4
A genetic disease is said to be autosomal recessive when
The gene involved is carried by an autosome (non-sex chromosome, X or Y in XY system of sexual determination);
The associated phenotype of this trait is recessive (the presence of two identical alleles is essential for the character to be expressed).
One of the two alleles is transmitted by the male gamete, the other by the female gamete.
But being a carrier of the mutation does not necessarily mean being sick, the manifestations of a genetic disease depend on its penetrance and the variability of its expression.
Upwelling is a process in which deep, cold water rises toward the surface. The water that rises to the surface is Rich in nutrients, which fertilizes the surface water.
Bryophytes are also called NON VASCULAR plants.
Bryophytes are a group of small and green plants, which are made up majorly of hornsworth, liverwort and mosses. They can be found on land or in aquatic environment. These plants do not produce flowers, therefore they are always described as seedless.
