Answer 2

Answer:

$\huge\boxed{\mathfrak{\red{\fcolorbox{red}{pink}{ Hiii:-}}}}$

Explanation:

Rather than giving a color allele and, separately, giving a shape allele to each gamete, the F1

dihybrid plant would simply give one “combo unit” to each gamete: a RR allele pair or a rr allele pair.

We can use a Punnett square to predict the results of self-fertilization in this case, as shown above. If the character 1and character 2 genes were in fact always inherited as a unit, or completely linked, a dihybrid cross should produce just two types of offspring, (first character) and (second character), in a 3:1ratio. Mendel's actual results were quite different from this (the 9:3:3:1ratio we saw earlier), telling him that the genes assorted independently.
