Front

What are the proteins on the surface of red blood cells?

Back

Antigens are proteins on the surface of red blood cells that determine blood type.

Front

How many alleles does an offspring receive from each parent for a specific trait?

Back

An offspring receives one allele from each parent.

Front

What is the probability of offspring having short tusks when a heterozygous long-tusked elephant is crossed with a homozygous recessive short-tusked elephant?

Back

The probability is 50%.

Front

What is the genotypic ratio of the offspring from a heterozygous cross?

Back

The genotypic ratio is 1:2:1.

Front

What is codominance in genetics?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed.

Front

Define complete dominance.

Back

Complete dominance occurs when the phenotype of the heterozygote is the same as that of the homozygous dominant.

Front

What is Mendelian genetics?

Back

Mendelian genetics is the study of how traits are inherited through the actions of alleles.

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, specifically the alleles present.
