A= big apples,r= red apples,a= small apples, andr= yellow apples. you have one tree that produces big yellow apples and another
tree that produces small red apples. when the two are crossed, you find that half of the new trees produce big red apples and half produce big yellow apples. what are the genotypes of the parents?
<span>Answer:
....|.Ar.....|.ar.....|.Ar.....|.ar.......
aR|.AaRr.|.aaRr.|.AaRr.|.aaRr.|
ar.|.Aarr...|.aarr..|.Aarr...|.aarr..|
aR|.AaRr.|.aaRr.|.AaRr.|.aaRr.|
ar.|.Aarr..|.aarr...|.Aarr..|.aarr...|
this is wrong because not all the apples are big
....|.Ar.....|.Ar.....|.Ar.....|.Ar.......
aR|.AaRr.|.AaRr.|.AaRr.|.AaRr.|
ar.|.Aarr...|.Aarr..|.Aarr...|.Aarr..|
aR|.AaRr.|.AaRr.|.AaRr.|.AaRr..|
ar.|.Aarr...|.Aarr..|.Aarr..|.Aarr...|
This one is correct, because the offspring in the first and third line are big and red, while the second and fourth have big yellow apples
so A is correct the parents are AArr and aaRr.</span>
Alternation of generations in plants permits both mitosis and meiosis but at different stages.
The zygote will undergo many rounds of <u>mitosis</u> and give rise to a diploid multicellular plant called a sporophyte. Specialized cells of the sporophyte will undergo <u>meiosis</u> and produce haploid spores.
<span>The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes.</span>
