Answer:

Question:

1. Determine the Genotypic and Phenotypic ratio.

2. What will be the sex of a child produced when an egg is fertilized by a sperm that has a Y chromosome?

3. What type of sperm must fertilize an egg to result in a female child?

4. Based on this Punnett Square, what percent of children would you expect to be male?

5. Which sex chromosome is present in both male and female?

6. Infer which sex chromosome determines a person's sex.

Answer:

1. The genotypic ratio describes the number of times a genotype would appear in the offspring after a test cross.

For example, a test cross between two organisms with same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr.

Phenotypic ratio pertains for the relative number of offspring manifesting a particular trait or combination of traits. ... in this case, the phenotypic ratio shall indicate how many of the offspring will be tall and how many will be short based on the genotype.

2. If the egg is fertilized with y chromosome then the child will be a male.

3. It's not about the type of sperm but, about the sex chromosome that emerge. An XX chromosome will produce a female while, a XY will produce male.

4. If a male and female organisms bred the chance of the offspring becoming a male will be always 50%.
