Sickle cell anaemia is an inherited autosomal recessive
alekssr [168]

Answer:

1/8 (12.5%)

Explanation:

An autosomal recessive disease is an inherited disease in which an individual need to receive both defective alleles at the same gene <em>locus</em> to be expressed in the phenotype. In this case, both parents are carriers of the recessive mutant allele associated with the sickle cell anaemia trait, thereby both parents are heterozygous, ie., each parent has one copy of the normal allele 'H' and one copy of the defective mutant allele 'h' associated with this condition. In consequence, their first child has a 1/4 (25%) chance of having sickle-cell anaemia. Moreover, the chance of having a girl is 1/2 and the chance of having a boy is 1/2, thereby the final chance of having a girl sickle cell anaemia individual is 1/4 x 1/2 = 1/8 (12.5%).

- Parental cross for sickle cell anaemia trait = Hh x Hh >>

- F1 = 1/4 HH (normal); 1/2 Hh (normal); 1/4 hh (sickle cell anaemia) >>  

- Sex proportion of sickle cell anaemia individuals =  1/8 female sickle cell anaemia individuals + 1/8 male sickle cell anaemia individuals (1/8 + 1/8 = 1/4)

Reika [66]

Answer: Glucose

Explanation:

The carbon based molecule which is broken by the cells of the body is glucose it is a carbohydrate that is obtained from food we consume it is stored in the form of glycogen. When the energy requirement of the body increases then glucose monomers are released from the glycogen chain so that glucose monomers can participate in the energy generation process in the mitochondria of the cell. The chemical energy so produced is ATP (adenosine triphosphate).
