The allele for white hair in mice is autosomal recessive (b), while the allele for black hair is autosomal dominant (B). A white, female mouse mates with a black, male mouse. If the offspring are half black and half white, what are the possible genotypes for the black, male mouse?
Bb or BB, heterozygous or homozygous dominant
What type of data is analyzed using a chi-squared ( χ2 ) test?
Categorical Data
What is the difference between an allele and a gene (locus)?
an allele is an alternate form of a gene
the allele for white hair in mice is autosomal recessive (b), while the allele for black hair is autosomal dominant (B). A white, female mouse mates with a black, male mouse. What are the possible genotypes for the white, female mouse
bb, homozygous recessive
What does the law of segregation state?
that only one allele from each locus is present in a gamete
