2. Cross a homozygous two horned zork with a heterozygous two horned

zork. What are the genotypes of the possible offspring? *

Answer 1

When crossing a homozygous two-horned zork (YY) with a heterozygous two-horned zork (Yy), the genotypes of the possible offspring are homozygous dominant (YY) or heterozygous (Yy), with a predicted genotypic ratio of 1:1.

Step-by-step explanation:

Crossing a Homozygous Two-Horned Zork with a Heterozygous Two-Horned Zork

When crossing a homozygous two-horned zork (let's assume the homozygous genotype is YY) with a heterozygous two-horned zork (Yy), we can predict the possible genotypes of their offspring using a Punnett square. The homozygous parent can only pass on the Y allele, while the heterozygous parent can pass on either the Y or y allele, giving us two possible combinations for the offspring's genotype: YY (homozygous dominant) or Yy (heterozygous).

Using a Punnett square:

The top row represents the alleles from the homozygous parent (YY).

The side column represents the alleles from the heterozygous parent (Yy).

The Punnett square would look like this:

Row 1: Y from homozygous parent, Y from heterozygous parent (YY)

Row 2: Y from homozygous parent, y from heterozygous parent (Yy)

There are two possible offspring genotypes:

YY (homozygous dominant)

Yy (heterozygous)

Thus, the offspring can either be homozygous dominant or heterozygous with a genotypic ratio of 1:1.

Answer 2

Heterozygous one horned zork.

Step-by-step explanation:

The Genotypes of the offspring include those listed, but is impossible to contain a B28-9 genotype in the substance. According to that, the one possible genotype would be a heterozygous one horned zork.
