11.2 Biology Worksheet Answers
Question: the principle of independent assortment states that __________ for different traits can segregate independently during the formation of gametes
Answer: genes
Question: what principle states that during gamete formation genes for different traits separate without influencing each other’s inheritance?
Answer: principle of independent assortment
Question: what is the probability that a cross between parents who are both homozygous recessive for a trait will have offspring that are homozygous recessive for that trait?
Answer: There is a probability that all the offspring will be homozygous with a recessive trait because those are the only traits given to them. 100%

Question: t or f: if mendel has found that an f2 cross of plants that were heterozygous for 2 traits had made an offspring with 2 phenotypes, this finding would have supported the theory of independent assortment
Answer: false
Question: t or f: the probability that a gamete produced by a pea plant heterozygous for stem height (Tt) will contain the recessive allele is 100%
Answer: false

Answer: 2
Question: A tall pea plant with yellow seeds is heterozygous for height and seed color (TtYy). This plant is crossed with a pea plant heterozygous for height but homozygous recessive for seed color (Ttyy). If 80 offspring are produced, how many are expected to be tall and have yellow seeds?
Answer: 30
