HELP!! dihybrid crosses

Answer:

Predicting the genotype of offspring. Determine all possible combinations of alleles in the gametes for each parent. Half of the gametes get a dominant S and a dominant Y allele; the other half of the gametes get a recessive s and a recessive y allele. Both parents produce 25% each of SY, Sy, sY, and sy.

Explanation:

This is an example of how you complete the problem. I hope this helps! :)

Final answer:

A dihybrid cross is a breeding experiment that shows how two distinct traits are passed from parents to offspring. It's done using a Punnett square to determine the probability of offspring combinations.

Explanation:

A dihybrid cross is a breeding experiment that involves parents that differ in two distinct, genetically determined traits. In the study of genetics, The aim of a dihybrid cross is to determine the likelihood of offspring inheriting combinations of traits from their parents.

For instance, let's consider an example of crossing two pea plants. One possesses the traits for being tall with yellow seeds (TTYY) and the other being short with green seeds (ttyy). We can observe a dihybrid cross to predict the progeny's traits.

To do so, a Punnett square is used to visualize all the potential combinations of gametes resulting from meiosis. Later, these combinations can be analyzed to find out the probability of an offspring manifesting a certain combination of traits.

In short, dihybrid crosses provide a systematic method to study how traits are passed on to offspring generation. Its findings are fundamental to understanding the principles of genetics.
