Find probability that benjamin will be homozygous recessive/ Biology
Part 1 of 2: In beans yellow (Y) is dominant to green (y) and smooth (S) is dominant to wrinkled (s). What are the possible genotypes for the offspring of the following cross: YySS and YYSs.
A. Yy, SS, YY, Ss
B.YYSS, YySS, YYSs, YySs
C. YYSS, YYss, yySS, yyss
D. YS, yS, YS, yS
Part 2 of 2: In beans with yellow (Y) dominant to green (y) and smooth (S) dominant to wrinkled (s): What are the phenotypes for the offspring in the example in the previous question?
A. 50% yellow smooth and 50% yellow wrinkled
B. 50% yellow smooth and 50% green smooth
C. 100% green wrinkled
D. 100% yellow smooth
The next three questions are based on the following information.
In humans, the ability to roll the tongue (T) is dominant over the inability to do so (t). Suppose Mike, who can roll his tongue, and Jeannie, who cannot roll her tongue, have a child, Benjamin.
Part 1 of 3: If Mike’s mother was able to roll her tongue but his father was not able to roll his, then what is the probability that Benjamin will be able to roll his tongue?
A. 75%
B. 50%
C. 100%
D. 0%
Part 2 of 3: What is the probability that Benjamin will be homozygous recessive?
A. 100%
B. 50%
C. 75%
D. 0%
Part 3 of 3: What is the probability that Benjamin will be homozygous dominant?
A. 50%
B. 100%
C. 0%
D. 75%
