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 correct answer is A. Athletes
That is because of all the training and exercises they do every day so they have to have much energy to consume.
The answer would be "<span>Cyclins are proteins that regulate when and how often a cell divides". Cyclins belong to a family of proteins that control the progression of a cell through its respective cell cycle. This is initiated by activating cyclin-dependent kinase (CDK) enzymes which regulate </span>transcription of RNA and process mRNA during mitosis.
