Answer the following The next three questions go together. You cross two individuals with genotypes AaBbCcdd and AaBbccDd. What is the likelihood one of their offspring will show the recessive phenotype at exactly three of the four traits ? What are the full, four -locus target genotypes for an offspring with the recessive phenotype at exactly three of the four traits? (Feel free to use the shorthand of A - ,B - , etc. for dominant genotypes .) HINT : There are four target genotypes ; you should list all four What are the individual likelihoods of the four-locus target genotypes you identified in the last question? Make it clear what likelihood corresponds to what target genotype . What is overall likelihood of an offspring having exactly three recessive phenotypes ?
hello, please answer the following Biology correctly. I don't need an explanation, just the correct answer choices. Thank you. Bio Question: "In cats, yellow color is due to one allele, and black color is due to another allele. The heterozygous condition results in a color known as tortoise shell, with both alleles expressed. This gene is on the X chromosome. Which is an expected result of a cross between a yellow male and a tortoise-shell female? Mark all answers that apply." A - 25% of offspring will be black males B - 50% of the offspring will be yellow C- 25% of offspring will be black females D- 50% of the males will be tortoise-shell
