2. Sexual reproduction also occurs in virtually all fungi. This
involves mating between two haploid hyphae. During mating, two
haploid parent cells fuse, forming a diploid spore called a
zygospore. The zygospore germinates, then it undergoes meiosis
which forms the haploid cells that develop into new hyphae.
One fungus lacks enzyme A - so cannot metabolize the compound X, so
compound Y is not formed and do compound Z also is not
formed.
Other fungus lacks enzyme C, so, cannot metabolize the compound Z
even Z is formed from Y. So in both of the above fungi, arginine is
not formed.
So, their progeny also can't synthesise arginine. That makes none
of them to survive on compound Y.
Hence, option A is the correct answer.
4. XO Drosophila are sterile males. In flies, the Y chromosome
is not involved in determining sex.
Hence, option E is the correct answer.
6a. The dominant trait is "purple".
Hence, option D is the correct answer.

A mutant plant with white flowers exists that lacks red anthocyanin pigment, normally made by enzyme P. Indeed the petal tissue lacks all detectable activity for enzyme P. Despite the lack of enzyme activity, a study of homozygous mutant cells using antibodies against the wild-type enzyme demonstrated that the cells homozygous for the mutation still had the enzyme (i.e., the antibody showed the presence of the enzyme). Which statement below could most likely explain these results? A )The mutant had...

the fruit fly, Drosophila melanogaster, an allele (v) of the gene vermillion gives flies purple eyes and is recessive to the wildtype red eye color (v+). An allele y of the yellow gene, gives flies a yellow body color compared to the dominant brown body color (yt). A heterozygous females for the two different mutations is test-crossed with mutant (i.e., homozygous recessive) males. The phenotypes of the progeny of this cross and their corresponding numbers are given below Yellow body,...

Question 10 (1 point) In Drosophila, the mutant black (b) has a black body and the wild-type (b+) has a gray body; the mutant vestigial (v) has wings that are short and crumpled compared the long wild-type wings (V+). These genes are linked and are located on the X- chromosome. A cross between a female fly and a black, vestigial winged male fly produced the following progeny: gray (b+), normal (v+) 20 gray (b+), vestigial (v)...

1. In loppins (fictitious diploid invertebrates), ear shape is controlled by two genes with two alleles each; upright ears (F) is dominant to floppy ears (f), and double-pointed ears (P) is dominant to single-pointed ears (p). Moreover, due to genetic interactions, floppy ears are always single-pointed. A loppin with floppy ears is crossed to a loppin with upright single-pointed ears, and the phenotypic ratios in the offspring are 2 floppy : 1 double-pointed upright : 1 single-pointed upright. What are...
