Answer:
1/4.
Explanation:
The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.
The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.
So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.
Answer:
As she is heterozygous, her genotype would be Aa. The eggs she produce would have one allele from her genotype, and thus she can produce A or a eggs.
<h2>
2nd statement is true.</h2>
Explanation:
Chromosomes are made up of genes and a gene is made up of two copies of alleles. If an organism has two different types of alleles on its chromosomes then it's a hybrid organism else we call it a pure organism/trait.
- Gene could be dominant or recessive.
- A phenotype is the expression of a trait.
- As 'tall' gene is considered to be dominant so so pea plant with even a single copy of 'tall' gene will have a tall phenotype.
I would say the second, third, fourth and fifth
It’s diffusion, net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.
