Two-Point Test Cross Problem

A test cross is a way to explore the relationship between genes and their respective alleles. It is a useful tool for genetic mapping and deciphering the inheritance of traits. Specifically, a two-point test cross examines two (2) genes at the same time to learn about their assortment in gamete formation.

A standard two-point test cross involves crossing a heterozygous organism for both genes with an organism that is homozygous recessive for both genes

For this problem, a test cross using a fruit fly (Drosophila melanogaster) heterozygous for two genes was conducted to understand their genetic interactions.

Characteristics of Recessive Phenotypes

Gene C is affiliated with the 'chummy' phenotype. A fruit fly that is homozygous recessive for Gene C shows behavior where it always maintains a close distance to other flies.
Gene J is associated with the 'jerky' phenotype. A fruit fly that is homozygous recessive for Gene J moves in rapid and sudden movements, displaying an unpredictable flight pattern.

Phenotype	Genotypes		Progeny Count
chummy, jerky	c	j	300
chummy	c	+	623
jerky	+	j	619
wildtype	+	+	258
TOTAL =			1,800

The resulting phenotypes are summarized in the table above.

Question

With the progeny data from the table, calculate the genetic distance between the two genes, expressing your answer in centimorgans (cM)

Important Tip 1: Your calculated distance between the genes should be a whole number. Finding a decimal in your answer, such as 5.5, indicates a mistake was made. Please provide your answer as a complete number without fractions or decimals.
Important Tip 2: Your answer should be written as a numerical value only, no spaces, commas, or units such as "cM" or "map units". For example, if the distance is fifty one centimorgans, simply write "51".

For this problem, a test cross using a fruit fly (Drosophila melanogaster) heterozygous for two genes was conducted to understand their genetic interactions.

Characteristics of Recessive Phenotypes

Gene A is linked with the 'artsy' phenotype. A fruit fly that is homozygous recessive for Gene A has wings that are colorful and distinctive patterns.
Gene F is connected with the 'fuzzy' phenotype. A fruit fly that is homozygous recessive for Gene F is covered in a dense layer of hairs, giving it a soft appearance.

Phenotype	Genotypes		Progeny Count
artsy, fuzzy	a	f	343
artsy	a	+	1,843
fuzzy	+	f	1,897
wildtype	+	+	317
TOTAL =			4,400

The resulting phenotypes are summarized in the table above.

Question

With the progeny data from the table, calculate the genetic distance between the two genes, expressing your answer in centimorgans (cM)

Important Tip 1: Your calculated distance between the genes should be a whole number. Finding a decimal in your answer, such as 5.5, indicates a mistake was made. Please provide your answer as a complete number without fractions or decimals.
Important Tip 2: Your answer should be written as a numerical value only, no spaces, commas, or units such as "cM" or "map units". For example, if the distance is fifty one centimorgans, simply write "51".

Two-Point Test Cross Problem

A standard two-point test cross involves crossing a heterozygous organism for both genes with an organism that is homozygous recessive for both genes

For this problem, a test cross using a fruit fly (Drosophila melanogaster) heterozygous for two genes was conducted to understand their genetic interactions.

Characteristics of Recessive Phenotypes

Gene A is affiliated with the 'artsy' phenotype. A fruit fly that is homozygous recessive for Gene A has wings that are colorful and distinctive patterns.
Gene P is correlated with the 'prickly' phenotype. A fruit fly that is homozygous recessive for Gene P is covered with sharp bristles, giving it a spiky texture.

Phenotype	Genotypes		Progeny Count
artsy, prickly	a	p	1,440
artsy	a	+	3,097
prickly	+	p	3,159
wildtype	+	+	1,504
TOTAL =			9,200

The resulting phenotypes are summarized in the table above.

For this problem, a test cross using a fruit fly (Drosophila melanogaster) heterozygous for two genes was conducted to understand their genetic interactions.

Characteristics of Recessive Phenotypes

Gene M is associated with the 'mushy' phenotype. A fruit fly that is homozygous recessive for Gene M feels soft to the touch and unusually squishy, unlike the usual firmness.
Gene W is associated with the 'waxy' phenotype. A fruit fly that is homozygous recessive for Gene W has a thick protective layer that is water resistant and opague.

Phenotype	Genotypes		Progeny Count
mushy, waxy	m	w	1,357
