Which of the eight parents are definitely heterozygous for Type O Allele?

A man and woman are both heterozygous for the recessive allele that causes cystic fibrosis. What is the probability that their first two offspring will have the disorder?

Is blood type an example of pleiotropy?

In humans, six fingers (F) is dominant to five fingers (f). Assume both parents are heterozygous for six fingers.b) What is the genotype of each parent?

Given the cross AaBbCc x Aabbcc, what is the probability of obtaining an offspring with the genotype aabbCc?

Can A+ father and B+ mother carries the recessive i allele (aka the o allele) and each parent is heterozyogous for the Rh allele, get a child with O+?

For individual lll-6, how do you get 2/3 for the probability of heterozygous? What are the three offspring you're talking about?

Are both incomplete dominance and codominance illustrated with two capital letters?

Explain the following features of the Mendelian traits and fill the Punnet Squares. a)The disappearance of recessive phenotype in the F1 generation. b)The genotype of an individual expressing dominant phenotype can be differentiated by the test cross.

Cystic fibrosis is a recessive human condition. A male with Cystic fibrosis and a woman with a dominant phenotype have sevral children, in which one displays Cystic fibrosis. What can you conclude about the genotype of the maternal parent and what is the probability that a child who does not display Cystic fibrosis is heterozygous?
