The genetic cross between a homozygous recessive individual and one of an unknown genotype is referred to as:

a) a self-cross; b) a test cross; c) a hybrid cross; d) an F1 cross; e) a dihybrid cross.

Show work, thank you.

Expert Solution

The genetic cross between a homozygous recessive individual and one of an unknown genotype is referred to as test cross. The genotypic and phenotypic ratio of a test cross is 1:1.

A test cross is performed to determine the genotype of a dominant parent .

When a test cross results in all dominant offsprings then the unknown genotype of the parent is said to be homozygous dominant.

When a test cross results in half of the progeny to be dominant and the other half to be recessive , then the unknown genotype of parent is heterozygous dominant.

At a particular locus, the homozygous genotype is lethal. We observe a cross between two heterozygous parents. Which of the following will not be true for their offspring: a) All offspring will look the same b) The genotype and phenotype ratios will be the same c) All offspring will be heterozygous d) Half of the offspring will die e) Genotype and phenotype ratio will be 1:2:1 what ratio would this offspring be?

The Bombay phenotype occurs when an individual human is homozygous for a recessive allele at the...

The Bombay phenotype occurs when an individual human is homozygous for a recessive allele at the FUT1 locus. Individuals with this genotype do not make a precursor substance required to synthesize the A and B antigens that sometimes appear on human red blood cells. Regardless of their genotype at the ABO blood type locus, individuals who are homozygous for the Bombay phenotype allele at the FUT1 locus will appear to have blood type O on standard blood type tests. Note:...

Assume that a cross is made between a heterozygous tall pea plant and a homozygous short pea plant. Fifty offspring are produced in the following frequency: 30 = tall 20 = short (a) What frequency of tall and short plants is expected? (b) To test the goodness of fit between the observed and expected values, provide the needed statement of the null hypothesis. (c) Compute a Chi-square value associated with the appropriate test of significance. (d) How many degrees of...

1.One of the concerns about genetic modification of agricultural plants is the possibility of cross-breeding between herbicide-resistant GMOs and weeds, creating “superweeds” that would be resistant to commonly used herbicides. EXPLAIN how PCR could be used to determine whether such cross-breeding had occurred.

A parental cross between homozygous cinnabar flies (cnbw+/cnbw+) and homozygous brown flies (cn+bw/cn+bw) is done. Use a Punnett square to show how the F1 cross will not produce homozygous double mutant flies in the F2 generation.
