Question

Interpret the Punnett square. A Punnett square with four rows and four columns. The first row is labeled big-A, big-B. The second row is labeled big-A, small-b. The third row is labeled small-a, big-B. The fourth row is labeled small-a, small-b. The first column is labeled big-A, big-B. The second column is labeled big-A. small-b. The third column is labeled small-a, big-B. The fourth column is labeled small-a, small-b. Drag "True" or "False" to the end of each statement. ResetHelp The genotypes shown represent gametes. False One of the possible offspring genotypes is AABB. True The parent genotypes are ABAbaBab×ABAbaBab. TrueThe parent genotypes are ABAbaBab×ABAbaBab. blank This cross shows two alleles for two traits. True The gametes are diploid and the offspring are diploid. True The genotypes shown are correct for a dihybrid cross. True

Answer 1

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.
