The bones in the front limbs of many mammals are similar in their structure and arrangement. What term is used to describe physical similarities between related species that indicates a common ancestry?

Answers

Answer 1
Answer:

The bones in the front limbs of many mammals are similar in their structure and arrangement because they have common ancestors. The term used to describe the physical similarities between related species is Homologous organs. A very common example of homologous structure in mammals are forelimbs of human, whale and dogs. These structure perform different function such that the forearm of human is used for holding things, flippers of whale are used for swimming and forearm of dog is used for walking and running.
Answer 2
Answer: The answer is homologous structures.

Homologous structures are similar structures shared by different species. For example, the anatomy of the front limbs of amphibians, lizards, and mammals, support the idea that these groups have a common ancestor. But since these groups are different enough to be separated into different classes, it can be concluded that they evolved from the common ancestor.

For four o'clock flowers, flower color is a case of incomplete dominance. The gene for flower color has two alleles: red (R) and white (r). What is the percent probability that one offspring from a parent with the genotype RR and a second parent with the genotype rr will have red flowers?

Answers

Answer:

0%

Explanation:

According to the question, the inheritance pattern of flower colour in four o'clock plants follow incomplete dominance i.e. one allele is not completely dominant over the other, and instead they form a heterozygous plant with a third intermediate phenotype (flower colour).

In this case, a four o'clock plant with genotype RR will have red flowers while a plant with genotype rr will have white flowers, Hence, they cross to form an all Rr genotype offsprings with pink flowers (since the red allele is incompletely dominant). Therefore, the percentage chance of having a red flower offspring from this cross is 0%, as it cannot occur.
