Question

If we consider two genes, r and m, in a human female, what is the probability that these genes are in one linkage groups?

Answer #1

The term linkage has 2 meanings

1 . On a same chromosome two or more gene where locate.

2.Genes that are close together tend to be transmitted as a unit.

Linkage

Genes nearby on the same chromosome tend to stay together during the formatioin of gametes.

According tithe Mendel conclusion about the linkage that the probability of a gamete will receive a allel is about 50 %.That in the above mentioned case female have 50 % chances of getting these genes in the linkage and thereby gamete also.

Consider two genes: R (round seeds) and r (wrinkled seeds) and
Y (yellow seeds) and y (green seeds). If two pea plants
mated (RrYy and RrYy), what would be the probability of producing
offspring with wrinkled seeds and green seeds? The
following picture shows the possible gametes. Make sure and use the
product rule.

In a breeding experiment, the male parent is known to have
either two dominant genes (symbolized by AA) or one dominant and
one recessive (Aa). These two cases are equally likely. The female
parent is known to have two recessive genes (aa). Since the
offspring gets one gene from each parent, it will be either Aa or
aa. [If the male parent is Aa, it is equally likely for the
offspring to get A or a from him]

A 3000 bp region of the human genome encodes two genes. One of
the genes encodes a protein of 700 amino acids and the other gene
encodes a protein of 310 amino acids. The mRNA sequences of the two
genes do not contain any of the same nucleotide sequences. How is
this possible? That's all the information given.
How are there no overlaps? Thats what I don't understand, I know
there are 2100 base pairs and and 900 base pairs,...

In a family with 7 children, male and female
distributed. Consider that the probability that the gender is male
to one of the children in this family is 0.5
Required :
a) What is the probability that the number of male children in this
family will be only one male??
b) What is the probability that the number of male children in this
family is greater or equal to three times the number of female
children in this family
?

What is the human male gamete? The human female
gamete?

Suppose that 56% of all college students are female and that we
randomly select 15 college students. a) What is the probability
that exactly 8 of the students will be female? b) What is the
probability that 10 or more of the students will be female? c) What
is the mean number μ of females in such randomly selected groups of
15 students? d) What is the standard deviation σ of the number of
females in such randomly selected groups...

Unicorn abilities are determined by two linked genes, the
ability to have a rainbow coat (R) is dominant to a white coat (r)
and the ability to fly (F) is dominant to the lack (f).
If these genes are linked by 15 map units what would be the
number of expected offspring of a heterozygous flying rainbow
unicorn with a homozygous white non-flying male if we had 300
offspring.

either CF or albinism?

Dominant alleles at two different loci affect the tail of mice.
These genes are linked and both are lethal in the embryo when
homozygous. One of the tail genes is called brachyury
(T), and these mice have short tails. A third gene,
histocompatibility-2 (H-2), is linked to the tail
genes and is concerned with tissue transplantation. Mice that are
H-2/+ will accept tissue grafts, unlike +/+. A
cross was carried out between male T H-2/ + + and female
+...

– During the embryogenesis, axial mesoderm cells are specialized
to express different genes. We identified three group of cells
present in close proximity. Among these groups one cell subtype
(known as Sub1) have probability of 0.5 to express gene XRA. The
other cell subtypes (known as Sub2 and Sub3) have a probability of
0.8 and 0.1 respectively.
Suppose that we isolated one of these cell subtypes at random
and grow them in the lab to study gene expression patterns. We...
