semster 2 final exam

The alleles present for a trait are the same describes homozygous.

Two parents think their baby was switched at the hospital. Its 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type “O,” the father has blood type “AB,” and the baby has blood type “B.”

The mothers genotype is :

The different forms of a gene is an allele.

Within a decade of the introduction of a new insecticide, nearly all of the descendants of the target pests were resistant to the usual sized dose. The most likely explanation for this is

see figure 2:
Which two animals in the table are most closely related?

Which of the following describes an organism that has the genotype Bb?

In chickens, rose comb (R) is dominant to single comb (r). A homozygous rose-combed rooster is mated with a single-combed hen. All of the chicks in the F1 generation were kept together as a group for several years. They were allowed to mate only within their own group. What is the expected phenotype of the F2 chicks?

The passing of characteristics from parents to offspring is heredity.

The exchange of genetic material between homologous chromosomes is described as crossing over.

In roses, the gene controlling flower color is controlled by Incomplete. Red (R ) is dominant to white (r) and is also dominant to pink ( Rr). What are the genotype/phenotypic ratios if a heterozygous flower and a heterozygous flower?

The type of cell division that produces gametes describes fertilization.

Cells that are 2n

Humans are primarily composed of:

A cell that contains one member of each chromosome pair describes homozygous.

Within a decade of the introduction of a new insecticide, nearly all of the descendants of the target pests were resistant to the usual-sized dose. The most likely explanation for this is

cells organized to perform a function:

See figure 1:
In which color of light did the algae grow best?

Two parents think their baby was switched at the hospital. Its 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type “O,” the father has blood type “AB,” and the baby has blood type “B.”

The baby’s blood type is:

Structures that have a similar embryological origin and structure but are adapted for different purposes, such as a bat wing and a human arm, are evidence for

During meiosis, gamete production results in:
