You have considered single locus and two locus (di) hybrid crosses for loci with alleles that are completely dominant/recessive.

a)Come up with a general rule for the proportion of offspring expected to have the phenotype of all the recessive traits associated with X autosomal loci when fully heterozygous parents are crossed.

b)Now, use that logic and provide the expected proportion of offspring that show recessive phenotype for 4 loci and the dominant phenotype the 5th locus when two fully heterozygous parents are crossed.

Homework Answers

Answer #1

A) The product rule is used to find the desired probability. We have to multiply the each independent event.

For Monohybdrid cross between heterozygous parent:

Parent: Aa × Aa

The probability of aa ( homozygous recessive ) is 1/4 as seen in the punnet square below.

Loci A and B are linked. Two heterozygotes are crossed. Individual one makes gametes in which both alleles in the gamete are either dominant or recessive (i.e. AB). The other organisms makes gametes in which the alleles are mixed (i.e. Ab). What is the phenotypic ratio of the offspring if the progeny if having dominant forms of both alleles produces a distinct phenotype versus those progeny having only one dominant allele?

assignment baldness In man, a gender-influenced character is determined by two alleles in an autosomal locus. Allel B for baldness is dominant in men, but recessive in women. The alternative allele b is recessive in men, but dominant in women. In a large population (A) it turned out that 1% of the women were bald. Answer the following questions assuming that the population is in Hardy-Weinberg's balance with regard to the genetic system considered. a) Calculate the expected frequency of...

"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...

For problem 1, to compute probabilities, the probability of event 1 AND event 2 is obtained by multiplying the two probabilities together, whereas the probability of event 1 OR event 2 is obtained by adding the two probabilities. 1.​Duchenne muscular dystrophy (DMD) is a condition that causes muscle degeneration and then death.
