Answer/Explanation:
Two unaffected parents can have affected children, that means cystic fibrosis must be a recessive trait.
The two parents must each have one copy of the cystic fibrosis allele, but are themselves unaffected. By chance, the son (shaded) inherited both of these copies and is affected. The daughter either inherited one or zero copies of the cystic fibrosis allele, as she is unaffected.
Some cells in a given tissue only have one mitochondria; in the case of muscle, because it requires so much energy to contract, a typical animal muscle cell can have upwards of 2000 mitochondria.
8 chromosomes. In reality each egg and sperm have 23 chromosomes each in order for produce a healthy zygote
Sucrose molecules do break down during cellular respiration
Answer:
The reason that gametes are haploid is because neither parent has the full set of genetic information so each must contribute their half to make a whole. An organism has two sets of genes from their parents, half a set from the mother and the other from the father (1/2 + 1/2= 1). So together the information carried by the two haploid cells come together for an organism to form.
