aaaaaaaaaa, help !!
so you're telling me its been almost 5 years with no answers
Honestly
I have a quick check that i have to do
1. right
2. wrong
3. right
4. right
5. wrong
6. right
7. right
1. The trait that is acquired is C) The ability of some gorillas to learn sign language. This trait is not determined by genetics, but rather by the individual's environment and learning experiences.
2. The height of a plant is dependent upon C) both genes and environment. While genes play a role in determining the potential height of a plant, environmental factors such as light, water, and nutrients also influence its actual growth.
3. A gene is to a chromosome as A) a pea is to its pod. A gene is a segment of DNA that contains the instructions for a specific trait, and it is located on a chromosome, similar to how a pea is enclosed within its pod.
4. Heredity is D) the passing of traits from parent to offspring. It refers to the transmission of genetic information from one generation to the next, resulting in the inheritance of certain traits or characteristics.
5. An offspring can inherit a recessive trait if A) one of its parents has the trait and the other is homozygous for the dominant trait. In order for a recessive trait to be expressed, an individual must inherit two copies of the recessive allele - one from each parent. If one parent carries the recessive trait and the other parent is homozygous for the dominant trait, there is a chance for the offspring to inherit the recessive trait.
6. In the case of incomplete dominance, the offspring of a curly-haired person and a straight-haired person will have C) wavy hair. In this scenario, neither allele is completely dominant over the other, resulting in an intermediate phenotype. Therefore, the offspring will exhibit a blend of the curly and straight hair traits, which is wavy hair.
7. If two people with wavy hair have offspring, you would expect C) 50% of their offspring to have wavy hair. In incomplete dominance, the heterozygous genotype (one allele for curly hair and one allele for straight hair) leads to an intermediate phenotype (wavy hair). Therefore, there is a 50% chance that each offspring will inherit the heterozygous genotype and exhibit wavy hair.
