Case study A man and woman are deciding whether to have a child. The genotype of the man includes a recessive allele for an inherited disease. The genotype of the woman does not include this allele. Both parents have a normal phenotype. Could the child inherit the
disease? Explain your reasoning. This is a great place to use your CER (Claim, Evidence, Reasoning) skills!

Explanation: When both parents are carriers for a recessive disorder, each child has a 1 in 4 (25 percent) chance of inheriting the two changed gene copies. A child who inherits two changed gene copies will be “affected,” meaning the child has the disorder.

Hope this helps! :)

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

a physical change is being made.
