Answer:
25% unaffected child with two normal gene.25% affected child with two recessive gene but 50% unaffected child but is a carrier
Explanation:
To have an autosomal recessive pattern you inherit two mutated gene one from each parent. It usually passed by two carriers. One recessive and other dominant.
Answer:
B. Sexual reproduction
Explanation:
Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).
In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.
Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.
Each kernel of corn inherits traits independently.
Each kernel of corn receives one allele from each parent for the traits of color and texture.
Corn can have multiple kernel colors because each kernel is independently formed.
Answer:
100%
Explanation:
This is a cross involving two different genes; one coding for seed pod color and the other for height in a plant. The allele for green seed pods (G) is dominant over the allele for yellow seed pod (g) in the first gene while the allele for tallness (T) is dominant over the allele for shortness (t) in the second gene.
According to the question, the two crossed plants are homozygous for their green seed pods and are short. Being homozygous for the green pod means that the parent plant will have a GG genotype for the first gene. A short plant exhibits the recessive trait, hence, will possess an homozygous recessive genotype i.e. tt. Therefore, the genotype of both parents crossed is: GGtt.
Each parent will undergo meiosis to produce gametes with the following allelic combinations: Gt, Gt, Gt and Gt. Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced and all offsprings will have the genotype: GGtt.
A GGtt offspring will phenotypically possess green seed pods and short traits. Since all the offsprings possess this green seed pod trait, hence, 100% of the offsprings have green seed pods
