(a)
To determine:
The probability of the off springs in the F2 generation if the F1 generation’s genotype is AaBbCcDd is, (a) aabbccdd (b) AaBbCcDd (c) AaBBccDd, (d) AaBBCCdd.
Introduction:
Tetrahybrid crosses involve e the use of 4 traits in consideration that produces 16 gametes in total. The possibilities can be 256. Each parent of the F1 generation will produce 16 gametes.
To determine:
The probability of the off springs in the F2 generation with genotype aabbccdd.
(b)
To determine:
The probability of the offsprings in the F2 generation with genotype AaBbCcDd.
(c)
To determine:
The probability of the offsprings in the F2 generation with genotype AaBBccDd.
(d)
To determine:
The probability of the offsprings in the F2 generation with genotype AaBBCCdd.

For keyboard navigation, use the up/down arrow keys to select an answer. a They are useful when the genotype of a dominant phenotype is unknown. b They are always done by crossing the dominant phenotype to a homozygous recessive individual for that trait. c This test is always done in humans. d A + B e A + C f B + Carrow_forwardUnder what conditions does one expect a 9:3:3:1 ratio? What may cause this ratio to vary? A. dihybrid cross with independent assortment; epistasis B trihybrid cross with linked chromosomes; Down syndrome C dihybrid cross with linked chromosomes; the 9:3:3:1 ratio will remain unchanged regardless of other conditions D. dihybrid cross with independent assortment; Turner syndrome E. monohybrid cross with independent assortment; epistasisarrow_forward
