regulatory genes

Why is it important to use individuals from pure breeding lines to start crosses?

to ensure they are homozygous

control of gene expression

The production of a new structure, following the removal of an existing structure, in an adult animal is known as ___.

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
