Which genotypes and genotypic probabili3es would you expect from crossing the following pea plants. Homozygous dominant (PP) with a

heterozygote (Pp)? 1. PP, Pp, pp 2. PP, Pp 3. PP, Pp, pp 4. PP, pp 5. PP, pp

This cell is in anaphase of meiosis I. How many chromosomes does the cell have?

1. 3 2. 6 3. 12 4. 24

You are studying a pea plant for 2 genes the gene alleles for ower colour are (P=purple and p=red) and the gene alleles for pea shape are (L=long and

l=round). You have a heterozygote for both genes (PpLl) and you cross it with a red, long plant (ppLl). What are the phenotypic ra3os of the ospring

assuming that dominant alleles are completely dominant?

1. 1 purple long : 1 red long: 1: red round : 1 purple round 2. 2 purple long : 2 red long: 2: red round : 2 purple round: 3. 3 purple long : 3 red long : 1 red round : 1 purple round 4. None of the above

You are studying a pea plant for 2 genes the gene alleles for ower colour are (P=purple and p=red) and the gene alleles for pea shape are (L=long and

l=round). You have a heterozygote for both genes (PpLl) and you cross it with a red, long plant (ppLl). What is the probability that an ospring would have the genotype ppLl? Assume that dominant alleles are completely dominant?
