Two pure-breeding lines of orange trees differ in the number of fruit segments they contain: One line produces fruit with 6 segments, and the other produces fruit with 10 segments. When these lines are crossed, the F1 produces fruit with 8 segments. When the F1 trees are crossed, the resulting F2 has nine phenotypic classes of trees, producing fruit with as few as 4 segments and as many as 12Assume that fruit segment number in orange trees is determined entirely by multiple unlinked, additive alleles.
Using the information above, complete the following statements by dragging one blue label to each blue target and one pink label to each pink target. Blue labels may be used once, more than once, or not at all.

Explanation:

from the data given...

n= 4

where n= # of genes

&, the extreme # of segments=  

Genes, which make up a genotype are instructions for encoding a phenotype, expressed as proteins in translation.

...one gene may have 2 alleles

An allele is an alternate form of a particular gene. Genes can have multiple alleles, but in this case...

∴4 genes= 4 × 2= 8 segments

Thus, each allele gives = 1 segment

one centimetre is equal to 0.01 metres

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
