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'


In a BB x bb cross?

In a BB x bb cross, all offspring will have the genotype Bb. The offspring will exhibit the dominant trait of the B allele.


What is the genotypes of offspring from the following cross AABB x aabb?

You make a box with 4 boxes in it and then you plug in the parents on the top and the side, which is the BBxBb, and match up the alleles (the letters) like coordinates in a graph. BBBBBBBBbBbb


In the cross BB x bb the percent of offspring in the F1 generation that will have the same genotype as their parents is?

In the cross BB x bb, all offspring in the F1 generation will have the genotype Bb, as they inherit one allele from each parent. None of the offspring will have the same genotype as either parent.


Whose chromosomes determine the sex of offspring in humans?

The males chromosomes determine the gender of the baby. Women have an XX chromosome and men have an XY chromosome. So women can only give an X chromosome, but men can give either/or.The chromosomes of the father make the final determination; the child either gets a X from the mother and either an X from the father which makes a girl, or an X from the mother and a Y from the father, which makes a boy.Jamiana:The Father's(it's Y though)

None - if the little boxes are taller than the big box!


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".
