Answer:

Cerebrosides

Explanation

Cerebrosides belong to a group of sphingolipids called glycosphingolipids. they are also commonly known as monoglycosylceramides because they contain only single unit of monosaccharide (that commonly is galactose) that is linked with ceramide.

Function:

They have very important role in nervous system because they are part of a group of lipids that are crucial component of biological membranes as well as regulators of their function.

Any problem associated with proper working of cerebrosides can cause cause organ dysfunctional diseases in humans.

Please see figure of cerebrosides in figure attached.

A couple in Indiana are each heterozygous for the autosomal recessive allele for albinism. They have two children. What is the p

irinina [24]

Answer:

Probability that both children will be phenotypically identical with regards to skin color is 10/16.

Explanation:

The couple has a heterozygous genotype for the recessive allele. Representing the recessive allele with 'a' and the dominant allele with 'A', we can write the heterozygous genotype for the couple as Aa.

The gene pool of the children for this couple can be represented as:

Alleles A a

A AA Aa

a Aa aa

There can result 4 combinations of alleles AA,Aa,Aa and aa. The recessive allele is responsible for albinism so the child with the allele set 'aa' will have albinism while the others, AA,Aa and Aa will show no signs of albinism since the recessive allele is responsible for it.

The probability that both children will be phenotypically identical can be calculated by first considering that the children show albinism and then consider the probability that they have a normal phenotype.

Probability that a child will have albinism (aa) = 1/4

Probability that a child will not have albinism (AA, Aa and Aa) = 3/4

Probability that both children have albinism = 1/4 x 1/4 = 1/16

Probability that both children will have no albinism = 3/4 x 3/4 = 9/16

Probability that both children will be phenotypically identical = 1/16 + 9/16

= 10/16

Probability that both children will be phenotypically identical with regards to skin color is 10/16.
