Answer:
The genotypes shown represent gametes. False
One of the possible offspring genotypes is AABB. True
The parent genotypes are ABAbaBab×ABAbaBab. True
The parent genotypes are ABAbaBab×ABAbaBab. True
This cross shows two alleles for two traits. True
The gametes are diploid and the offspring are diploid. False
The genotypes shown are correct for a dihybrid cross. True
Explanation:
║ AB ║ Ab ║ aB ║ ab
AB║ABAB ║ ABAb║ABaB║ABab
Ab║ AbAB║ AbAb ║AbaB║Abab
aB║aBAB ║ aBAb ║aBaB║aBab
ab║abAB ║ abAb ║abaB ║abab
Drawing the Punnett square we can deduce that the genotypes shown do not represent gametes because there are more than 2 pairs of chromosomes.
As shown in the second column second row of the Punnett square one of the possible genotypes is AABB, it is distributed different (ABAB) but it is the same possible genotype.
The parents' genotypes are the ones that are written in the first columns and first row, they coincide with the ones in the statement.
A dihybrid cross shows the cross between two genes that have different traits.
The gametes are always haploid and the offspring are diploid because the two gametes come together.
