Genetics

Front

What is the genotype of a horse with white hair if W represents white hair and w represents non-white hair?

Back

WW

Front

If a horse with genotype WW is crossed with a horse with genotype ww, what fraction of the offspring will have white hair?

Back

All (100%) of the offspring will have white hair.

Front

What percentage of chromosomes do puppies share with their mother?

Back

50%.

Front

What is the genotype for a yellow plant if G represents green and g represents yellow?

Back

gg.

Front

What does the term 'homozygous dominant' mean?

Back

An organism with two identical dominant alleles for a trait (e.g., AA).

Front

What is incomplete dominance in genetics?

Back

A situation in which neither allele is completely dominant, resulting in a phenotype that is a blend of the two alleles.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What is the expected phenotype ratio in a monohybrid cross?

Back

Typically 3:1 for dominant to recessive traits.

Front

What is the purpose of a Punnett square in genetics?

Back

To predict the genotypes and phenotypes of offspring from a genetic cross.

Front

Define the term 'allele'.

Back

An allele is a variant form of a gene that can produce different traits.
