A diploid cell divides giving rise to two diploid daughter cells. What mechanism of division did this cell undergo?

T/F A female mammal that is heterozygous for a trait carried on the X chromosome will only ever demonstrate the dominant phenotype.

After correctly transcribing the DNA sequence above, another BIOL 190 student then translated the resulting mRNA and gave the following answer: phenylalanine, lysine, tryptophan, methionine, tyrosine, arginine, asparagine, alanine, leucine, threonine, isoleucine, leucine, tryptophan, arginine, glutamate Is this correct?

Which cell is in interphase?  

At what stage of meiosis is the independent assortment of chromosomes determined?

Legun’s blood type is AB and his sister’s blood type is O.  Their parents blood types must be:

Mendel’s work demonstrated that traits are inherited as:

A manifesting heterozygote…

The trait of medium-sized leaves in iris is determined by the genetic condition PP’. Plants with large leaves are PP, while plants with small leaves are P’P’. A cross is made between two plants each with medium-sized leaves. They produce 80 seedlings. How would you describe the genotype of the plants with medium-sized leaves?

The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by a recessive mutant gene that independently assorts with a recessive gene for hairy (h ) body. Assume that a cross is made between a fly with normal wings (homozygous) and a hairy body and a fly with vestigial wings and normal body hair (homozygous). The wild-type F1 flies were crossed among each other to produce 1024 offspring. How many of the flies would you expect to have both vestigial wings and a hairy body?
