What alleles do the f1 offspring have and why?
The alleles of the f1 offspring will depend on the alleles of the parents. In theory all of the alleles in the parental genotypes could be present in the f1 generation.To work out which combinations of alleles will be present in the f1 generation/the proportion with one allele etc. you would need to draw some kind of cross.AA x AaA AA AA AAa aA aASo the f1 offspring have both the A and a alleles, because the two alleles from each parent are separated into the gametesAA gives two gametes both with 'A' alleleAa gives on gamete with 'A' and one with 'a'
How many characteristics does each gene contral?
2 genes control each characteristic of an offspring. x
What alleles would the offspring have if both parents are pure a or pure A?
If the parents are both AA, which results in the cross AA X AA, then the offspring will all be AA. If both parents are AA, resulting in the cross AA X AA, then all offspring will be AA. If BOTH parents are Aa, resulting in the cross Aa X Aa, then the offspring will be 25% AA, 50% Aa, and 25% AA. This is only true if the alleles are not sex-linked.
What the x and Y chromosomes affect?
They determine the sex of the offspring in Humans.
Whose chromosomes determine the sex of offspring in humans?
In humans, it is the father's chromosomes that determine the sex of offspring. The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome. If the combination is XX, the offspring is female, and if it's XY, the offspring is male.
Producing a homozygous offspring with AAA x AAA cross?
25%
The F1 offspring of the monohybrid cross AAA x AAA are?
F1 offspring obtained by monohybrid cross of AA and AA will be Aa.
How many boxes does a Dihybrid cross have?
A dihybrid cross results in 16 boxes for the offspring. For example, the cross RrDd X RrDd is shown below:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
What is the probability that the genotype AAA will be produced by the parents AAA x AAA?
offspring will be produced in following AA :Aa:aa and is in the ratio of 1:2:1 so the probabiltiy is 50%
What is the genotypic ratio of the offspring from a cross of AAA x AAA?
The genotypic ratio of a cross of Aa and Aa is: one AA, one aa, and two Aa. Or 1:2:1
How many boxes could a 52.5' x 102 x 94 trailer hold?
And the boxes are how big ????
How many boxes is there if you have a square that has 6 boxes in a row across and down?
6 x 6 = 36 boxes
How many boxes in a 3 x 3 grid?
There are 9 boxes in a 3x3 grid.
How many boxes measuring 3.0 x 5.0 cm can fit into a carton 30.0 x 40.0 cm?
80 eight boxes wide by ten boxes long
How many boxes can fit in a 7feetx7feetx8feet cube?
That depends on the size of the little boxes. If they're all 1-cubic-foot boxes, then you can fit (7 x 7 x 8) = 392 of them in there. And by the way ... 7 x 7 x 8 is not a "cube".
How many 8cm x 6cm boxes will fit into a 50cm x 35 cm box?
None - if the little boxes are taller than the big box!
How many boxes that covers 23.97 sq ft will it take to do a room 17' L x 13' W?
17 x 13 = 221 221/23.97 = 9.22 9.22 boxes or 10 whole boxes.
