Which genotypes and genotypic probabili3es would you expect from crossing the following pea plants. Homozygous dominant (PP) with a heterozygote (Pp)? 1. ½ PP, ¼ Pp, ¼ pp 2. ½ PP, ½ Pp 3. ¼ PP, ½ Pp, ¼ pp 4. ¾ PP, ¼ pp 5. ¼ PP, ¾ 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
