Explanation:
The identification is based primarily on the analysis of one or two regions of the ribosomal DNA: sequencing of the D1 / D2 domains of the 28S rRNA gene and / or of the ITS region (ITS1 and ITS2 intergenic spaces and that includes the 5.8S rRNA gene ). Its comparison with the sequences available in public databases allows the strains to be assigned to a specific species when the homology percentage of its sequences is greater than or equal to 99%.
Answer:
Proportion of the F2 male with red eyes and forked bristle will be 1/4
Explanation:
forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+).
Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b+)
A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes
X+X+b+b+ x Xfbb
the F1 gives 1/2X+Xf 1/2b+b
1/2X+Y 1/2b+b
intercross of F1
Proportion of the F2 male with red eyes and forked bristle will be
forked bristle= Xfy = 1/2 and for red eyes 2/4= 1/2 = 1/2x1/2 =1/4

The uterine horns are the points where the uterus and the fallopian tubes meet. They are one of the points of attachment for the round ligament of uterus (the other being the mons pubis). ... The spare egg, that cannot travel the fallopian tube, is absorbed into the body.
