Show the possible genotypes and phenotypes of the offspring from a cross between a heterozygous male with type A blood and a heterozygous female with type B blood.

here

Explanation:

Heterozygous male with type blood A has the genotype of IA IO. Heterozygous female with blood type B has the genotype of IB IO.

Crossing IA IO × IB IO;

25% IA IB - blood type AB

25% IA IO - blood type A

25% IB IO - blood type B

25% IO IO - blood type O

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
