Quiz 4/3 Mendelian Genetics Block A

Which combination is Homozygous Dominant

• HH
• Hh
• hh
• hH

What do we call the result of the genotype (for example, the color of the peas)?

• Visible traits
• Physiotrait
• Genotype 2
• Phenotype

Which is the correct phenotype for this organism?

• BB
• blue
• green
• bb

Different variations of a gene are called?

• Alleles
• DNA
• Chromosome
• Gene

If the dominant phenotype is round petals and the recessive genotype of pointed petals, what is the possibility that the offspring will have pointed petals?

• 0%
• 25%
• 50%
• 75%
• 100%

Phenotype is

• what is on the chromosome pairs, like Ww
• what the organism looks like, like brown eyes

Imagine that in roses, there is an allele for the color that has a dominant allele and a recessive allele. The dominant allele, W, codes for white petals and the recessive allele w is black petals. A Ww rose is

• homozygous genotype and black phenotype
• heterozygous genotype and white phenotype
• black genotype and homozygous phenotype
• white genotype and homozygous phenotype

A heterozygous striped wild pig (Ss) is crossed with a black wild pig (ss). Perform a Punnett square cross and determine the genotype and %.

• 100% Ss
• 50% Ss, 50% ss
• 75%Ss, 25%ss
• 25%SS, 50%Ss, 25%ss

If long hair were dominant in guinea pigs, what is most likely true about this one?

• This guinea pig received two dominant traits. (HH)
• This guinea pig cannot have a recessive allele. (h)
• This guinea pig could be homozygous dominant (HH) or heterozygous (Hh)
• This guinea pig is homozygous recessive (hh)

Let's assume that the trait for a long ears vs. pointy ears is Mendelian in dogs, with a long ears being dominant (E). The female parent is EE and the male parent is ee. Is it possible for them to have puppies with pointy ears?

• Yes
• No
