A flowering shrub has two possible flower color traits: red and white. The dominant allele (R) codes for red flowers, the recessive allele (r) codes for white flowers. A heterozygous red- flowered shrub is cross-pollinated by a white-flowered shrub.Which Punnett square would you use to predict the probability of shrub offspring having red or white flowers?

When 2 heterozygous parents are crossed, 75% of their offspring will have the dominant trait.

Gabriela has blue eyes and her parents have brown eyes. Based on this information, she develops the following Punnett square. How is it possible for her to have a different eye color than her parents?

The blue eye color trait skipped a generation.

She got her eye color from her mother’s DNA.

Her eye color was affected by the environment.

She received one blue allele from each parent.

Gregor Mendel was an Austrian monk who studied heredity by doing experiments breeding pea plants with different features. In one experiment he found that the offspring of round-seeded parents produced a mixture of round-seeded and wrinkle-seeded offspring. How did he know that they had reproduced sexually and not asexually?

The pea plants usually produced identical plants to the parents.

Peas cannot reproduce sexually.

The offspring were sometimes different than the parent plant.

The wrinkliness of the seeds is determined by the amount of water the plants receive.

Zoologists are scientists who study the physical characteristics, behaviors, and interactions of animals-including reproduction. A team of zoologists is studying Hydra and dolphins. Hydra reproduces asexually, and dolphins reproduce sexually. The team developed models to compare the reproduction of the two organisms. Observe the models and decide which statement best describes how offspring produced by asexual reproduction compare to those produced by sexual reproduction.

Sexual and asexual reproduction both produce offspring with genetic material identical to their parents.

In sexual reproduction, offspring receive genetic material from two parents. In asexual reproduction, offspring receive offspring receive genetic material from one parent.

In sexual reproduction, offspring receive genetic material from one parent. In asexual reproduction, offspring receive offspring receive genetic material from two parents.

Sexual and asexual reproduction both produce offspring with genetic material different from their parents.

22.

Select the word to complete the sentence. In sexual reproduction, offspring receive DNA from __________________

one parent

both parents

23.

Select the word to complete the sentence. In asexual reproduction, the offspring's genetic material comes from ___________

one parent

both parents

24.

A group of scientists is working to increase a population of black-footed ferrets. The model shows how the gene determining claw strength is passed from parents to offspring through sexual reproduction. Use the model to select the statement that best describe why sexual reproduction results in offspring with genetic variation.

The offspring receive both of the father's alleles, so the offspring will have all the same genes as the father.

The offspring receive one allele from each parent, so the offspring won't have genes that are identical to either parent.

The offspring can't have the same genetic information as either parent, so new genes are created.
