Question 11 (1 point)

In yeast, mating aBD x Abd produces the following haploid spores:

aBD = 385; Abd = 386

ABD = 387; abd = 385

abD = 34; ABd = 35

aBd = 36; AbD = 37

What is the best conclusion that can be made from this data?

Question 11 options:

All 3 genes are unlinked

All 3 genes are linked

Genes A and B are linked, but gene D is unlinked

Genes B and D are linked, but gene A is unlinked

Genes A and D are linked, but gene B is unlinked

Question 12 (1 point)

From a three-point testcross mapping experiment, the following gamete data is obtained:

ABC 365; abc 367

aBc 110; AbC 105

aBC 4; Abc 3

ABc 25; abC 21

From the above data, what can be said of the genes?

Question 12 options:

All the genes are unlinked

The gene order is ABC

The gene order is ACB

The gene order is CAB

2 of the genes are linked, and one of the genes is independently assorting

Solution

11) In this data aBD x Abd the linked genes inherits the character of the other genes from the interpreted haploid data we can see that the gene A remains unchanged while other genes becomes inherited the linked gene so we can say that genes B and D are linked and gene A is unlinked so according to this data fourth statement is correct.

12) In the Three-point testcross considers the inheritance of three alleles. in this data all the characters are inherited so all the genes are unlinked as none of the characters are inherited in any of the genes. So the first statement is true.
