Mendel Dominance Punnett

In Mendelian Genetics (Named after Gregor Mendel), what is a dominant trait?

• A trait or characteristic that will appear in the offspring if one or both of the parents contributes it.

• The trait or characteristic that takes charge and all other traits follow.

• The trait or characteristic that asserts itself in the group of traits.

• The trait or characteristic that appears to disappear in the offspring.

In Mendilian genetics, what is the recessive trait?

• A trait or characteristic that will appear in the offspring if one or both of the parents contributes it.

• The trait or characteristic that takes charge and other traits follow.

• The trait or characteristic that asserts itself in the group of traits.

• The trait or characteristic that appears to disappear in the offspring.

What is a phenotype?

• The type of pheno in the genes.

• The visible or physical trait resulting from the allele pair.

• The genetic combination of allele's in the allele pair.

• The length of the chromosome.

What is a genotype?

• The type of geno in the genes.

• The visible or physical trait resulting from the allele pair.

• The genetic combination of allele's in the allele pair.

• The width of the chromosome.

What is a Punnett Square used for in Mendelian Genetics?

• A tool used in genetics to draw squares.

• A mathematical equation used to identify whether offspring resulted from mitosis or meiosis.

• A Punnett Square allows the prediction of the percentages or probability of phenotypes in the offspring from known genotypes.

• A square used to organize all the genes in a numerical sequence from the lower number to the highest number.
