Homework Answers
Answer. As we know females have two X chromosome and male has one X chromosome, so Rett syndrome is lethal for boys when it has mutated X chromosome while female can have this syndrome which relates to slower development of body and brain.

Two dominant mutations that are linked on the third chromosome
and each is homozyogus recessive lethal: Tubby (Tb) in the Tb+ gene
results in short/fat “tubby“ bodies. Another dominant mutation
serrate (Ser) in the Ser+ gene results in serrated wings. Tb flies
with normal wings were crossed to Ser flies with normal body.
Assuming no recombination, the expected progeny and their
proportions are:

X-linked Agammaglobulinemia (also known as Bruton Agammaglobulinemia) is caused by a mutation in the gene coding for Bruton tyrosine kinase (BTK). From the research you did after reading the case, what is the role of BTK and how are B-lymphocytes affected?

An enzyme, encoded by gene A, converts substrate X into product Y. Individuals with a dominant mutation in gene A over accumulate substrate X, which causes severe neurological symptoms. At the molecular level, this enzyme functions as a homodimer. A homodimer is a protein composed of two subunits that are encoded by the same gene. Let’s suppose you are able to purify subunits from cell samples and then mix them together under conditions in which they form homodimers, and you...

INTRODUCTION
New mutations that arise on the X chromosome can have different
likelihoods of becoming fixed in the population than their
autosomal counterparts. This differential likelihood arises because
the effect of a recessive mutation on an autosome is only expressed
in homozygotes, whereas the effect of a similar recessive mutation
that arises on the X chromosome in a male is fully expressed. Thus,
advantageous recessive mutations are more likely to become fixed if
they are on the X chromosome than...
